Booster recommendations for pregnant women, teens, and other groups explained
These recommendations have been widened because of the continued emergence of new variants of the virus and the wane of protection over time for both vaccinations and previous disease.
The new recommendations take away some of the questions surrounding eligibility for booster vaccinations while potentially leaving some additional questions. All in all, they provide flexibility for individuals to help protect themselves against the COVID-19 virus, as many are considering celebrating the holidays with friends and family.
The first item that has become clear is that all individuals over 18 are now not only eligible for a booster vaccination a certain time after they have completed their series, but have a recommendation for one.1
But what about a fourth dose? There is a possibility that some patients should be receiving one. For those who require a three-dose series due to a condition that makes them immunocompromised, they should receive their booster vaccination six months after completion of the three-dose series. This distinction may cause confusion for some, but is important for those immunocompromised.
Boosters in women who are pregnant
The recommendations also include specific comments about individuals who are pregnant. Although initial studies did not include pregnant individuals, there has been increasing real world data that vaccination against COVID, including booster vaccinations, is safe and recommended. As pregnancy increases the risk of severe disease if infected by COVID-19, both the CDC and the American College of Obstetricians and Gynecologists,2 along with other specialty organizations, such as the Royal College of Obstetricians and Gynaecologists, recommend vaccinations for pregnant individuals.
The CDC goes on to describe that there is no evidence of vaccination increasing the risk of infertility. The vaccine protects the pregnant individual and also provides protection to the baby once born. The same is true of breastfeeding individuals.3
I hope that this information allows physicians to feel comfortable recommending vaccinations and boosters to those who are pregnant and breast feeding.
Expanded recommendations for those aged 16-17 years
Recently, the CDC also expanded booster recommendations to include those aged 16-17 years, 6 months after completing their vaccine series.
Those under 18 are currently only able to receive the Pfizer-BioNtech vaccine. This new guidance has left some parents wondering if there will also be approval for booster vaccinations soon for those aged 12-16 who are approaching or have reached six months past the initial vaccine.1
Booster brand for those over 18 years?
Although the recommendation has been simplified for all over age 18 years, there is still a decision to be made about which vaccine to use as the booster.
The recommendations allow individuals to decide which brand of vaccine they would like to have as a booster. They may choose to be vaccinated with the same vaccine they originally received or with a different vaccine. This vaccine flexibility may cause confusion, but ultimately is a good thing as it allows individuals to receive whatever vaccine is available and most convenient. This also allows individuals who have been vaccinated outside of the United States by a different brand of vaccine to also receive a booster vaccination with one of the options available here.
Take home message
Overall, the expansion of booster recommendations will help everyone avoid severe disease from COVID-19 infections. Physicians now have more clarity on who should be receiving these vaccines. Along with testing, masking, and appropriate distancing, these recommendations should help prevent severe disease and death from COVID-19.

IUDs may increase background enhancement on breast MRI
Intrauterine contraceptive devices (IUDs) have been linked to increased background enhancement on breast MRI, according to research presented at the Radiological Society of North America 2021 annual meeting.
About 10.4% of women 15-49 years of age who use contraception have an IUD or contraceptive implant, according to the Centers for Disease Control and Prevention. Unlike oral or transdermal hormonal contraceptives and hormone replacement therapy, levonorgestrel-releasing IUDs release a small amount of the hormone directly into the uterus and are thought to have a much more localized effect, Luisa Huck, MD, the lead author of the study, said in an interview.
But women with IUDs have long reported adverse effects associated with other hormonal medication. “In the past, some women reported depression, headaches, sleep disorders, and panic attacks,” noted Dr. Huck, a radiology resident at RWTH Aachen University in Germany.
Christiane Kuhl, MD, chief of the department of radiology at RWTH Aachen University and senior author of the research, had also observed that women with hormonal IUDs often have increased background parenchymal enhancement (BPE) on contrast-enhanced MRI. BPE “has been established as a sensitive marker of hormonal stimulation of breast,” the study authors wrote, and previous studies have shown that women using hormonal medications have higher BPE on breast MRIs.
To better understand whether IUDs can increase BPE, Dr. Huck and colleagues used the hospital database to search for premenopausal women who had undergone breast MRIs for screening between January 2014 and July 2020. To be included, women had to have had at least two scans: one with and one without an IUD in place, with the scan conducted at least 4 weeks after IUD placement or removal. All women in the study had no history of breast cancer or hormone or antihormone intake.
The study involved 48 women with an average age of 45 years and a median of 27 months between the two scans. Forty-six of the women had the Mirena levonorgestrel-releasing IUD and two had the Jaydess IUD. To account for hormone variations between patients, the researchers used each patient as their own reference point. To control for age-related effects, 25 women had their first MRI without an IUD and their second scan with an IUD in place. The second group of 23 women underwent their first MRI with an IUD and had it removed before the second scan.
Hormonal effects on breast enhancement are very complex, and hormonal stimulation is not always predictably correlated with changes on MRI imaging.
For 23 women in the study, background enhancement was higher on scans with the IUD than without (P < .001). For 24 women, there was no change in BPE with or without an IUD, and one woman had lower BPE with an IUD than without.
“It is very interesting and relevant to practice to consider that the presence of an intrauterine device would have potential impact on the enhancement we see in the breast on MRI imaging,” Samantha Heller, MD, PhD, associate professor of radiology at New York University, said in an interview.
However, the study used BPE as a measure for hormonal shifts, and “hormonal effects on breast enhancement are very complex, and hormonal stimulation is not always predictably correlated with changes on MRI imaging,” she noted. BPE on MRI can fluctuate, so testing actual hormone levels in patients with elevated BPE could be helpful to identify hormonal shifts, she added. It is also important to understand why half of the women in the study showed no variation in BPE, she said.
The study findings are not very surprising, considering that it is known that low levels of progesterone from IUDs circulate in the blood stream, Frances Casey, MD, MPH, associate professor in the department of obstetrics and gynecology at Virginia Commonwealth University in Richmond, said in an interview. They do not suggest that there should be any changes to IUD guidelines, she added.
However, “the study findings raise the question as to whether IUD status should be documented as a matter of course prior to performing breast MRI,” said Dr. Heller. “It is standard to document the timing of a woman’s menstrual cycle, as well as to note any hormone suppression or replacement therapy. This is in part so that the radiologist may understand the etiology of any observed variation in background enhancement,” she explained.
Although increased enhancement on MRI has sometimes been linked to higher chances of recommendations for additional imaging or biopsies, she noted, “more work would be needed to understand the impact – if any – of an IUD on breast MRI recommendations due to enhancement changes.”
Dr. Huck, Dr. Heller, and Dr. Casey disclosed no relevant financial relationships.

Treating unexplained infertility – avoiding trial and error
Physicians who care for women having difficulty conceiving must understand the devastation their patients feel while knowing how to define infertility, when (and when not) to advise an evaluation, and offer evidence-based treatment options. Analogous to a mother desiring an antibiotic prescription for her child’s common cold, infertility patients can be desperate for an evaluation and treatment, despite the lack of an indication. This month’s article addresses the diagnosis and management of unexplained infertility.
The chronological age of a woman is the leading prognostic factor for successful reproduction. The definition of infertility remains 1 year of an inability to conceive in a couple who have no demonstrable risk factors, such as ovulation dysfunction, prior infertility, or known male factor. In women less than age 30, monthly fecundity rates are between 20% and 37% during the first 3 months of trying to conceive. The chance of success increases to 80% after 1 year and 90% after 2 years of trying to conceive, according to the American Society of Reproductive Medicine. Nevertheless, following unsuccessful attempts at conception by a couple, the physician should offer an evaluation based on the woman’s age – 1 year for women less than age 35, 6 months for women aged 35-39, and 3 months for women aged 40 and older. Testing can be initiated earlier if there are predisposing factors impairing fertility.
The basic infertility evaluation consists of a thorough history of the couple, a review of medical records, and an assessment of ovulation, fallopian tube patency, and sperm parameters on analysis. In the interest of efficiency, given that couples are typically anxious, these three areas can be evaluated within 1 month. In years past, a diagnostic laparoscopy was considered the gold standard of necessity to provide the diagnosis of exclusion, that is, unexplained infertility. This surgical procedure has fallen out of favor given the low diagnostic yield in a woman with a normal hysterosalpingogram, pelvic ultrasound, and no risk for a pelvic factor; for example, prior abdominal myomectomy, bowel surgery, or strong suspicion for endometriosis based on symptoms including significant pelvic pain affecting activities of daily living.
Initial laboratory testing should be judiciously ordered by recommending only those that will affect management, that is, prenatal labs to assess immunity to rubella and varicella along with a baseline thyroid-stimulating hormone, CBC, blood type, and Rh and antibody screen. In a woman with monthly ovulatory menstrual cycles and no signs of hirsutism or galactorrhea, the clinical utility of obtaining follicle-stimulating hormone, luteinizing hormone (LH), estradiol, prolactin, total and free testosterone, and dehydroepiandrosterone lack evidence. Further, a random anti-Müllerian hormone (without prior chemotherapy, radiation, or ovarian surgery) lacks value as the natural pregnancy rate does not appear to be affected, although low AMH has been associated with an increased risk for miscarriage.
Although not typically screened, measles can cause significant complications in pregnancy including an increased risk of maternal hospitalization and pneumonia, as well as miscarriage, stillbirth, low birth weight, and increased risk of preterm delivery.
Education is an important tool to guide patients and begins with an explanation of urine LH timed intercourse. From the onset of the LH surge, the oocyte is released in 24-36 hours, i.e., the actual day of ovulation is estimated to be the day after the urine LH surge. The “fertile window” appears to be the 5 days before plus the day of ovulation but the highest chance of conception occurs within the 2 days before and including the day of ovulation.
Empiric treatment may be offered when no demonstrable etiology has been identified, lifestyle factors have been addressed (for example, elevated female body mass index, tobacco use by the couple), and medical conditions have been optimized. Reproductive capability declines with continued attempts at conception such that, by 2 years, the approximate monthly fecundity rate is 3%-4%.
The first-line treatment of unexplained infertility is clomiphene citrate (CC) with intrauterine insemination. Letrozole, while not Food and Drug Administration approved for infertility treatment, has been shown in multiple studies to be equally effective as CC and to have a good safety profile. In a recent study, the cumulative live-birth rate over three cycles with CC and IUI, compared with expectant management was 31% versus 9%, respectively. Further, multiple studies failed to show a difference in pregnancy outcomes when comparing CC and IUI with letrozole and IUI.
It is vital to note that, for women who ovulate, studies do not support the use of CC without the addition of intrauterine insemination (IUI). The monthly fecundity rate of a cycle of CC without IUI is similar to natural conception attempts with urine LH timed intercourse, that is, without ovarian stimulation.
Recommendations (along with the level of evidence) from ASRM guidelines
- 1. Natural cycle, that is, without ovarian stimulation, timed with IUI is equivalent to expectant management (strong)
- 2. CC or letrozole with timed intercourse is no more effective than a natural cycle (good)
- 3. Pregnancy rates using gonadotropins with timed intercourse have not been shown to be superior to oral ovarian stimulating medications but risks multiple gestation (insufficient)
- 4. CC plus standard-dose gonadotropins results in higher pregnancy rates, there is good evidence for an increased risk of multiple gestation (fair)
- 5. Treatment with gonadotropins alone with IUI is superior to CC or letrozole with IUI; the risk of a multiple gestation rate remains significant (insufficient)
- 6. IUI can be performed between 0 and 36 hours following human chorionic gonadotropin trigger and performing one IUI in a cycle has equivalent success as two (fair)
- 7. Immediate IVF in women older than 38 years may be associated with a higher pregnancy rate and shorter time to pregnancy, compared with ovarian stimulation/IUI cycles before IVF (good)
Conclusion
It is recommended that couples with unexplained infertility initially undergo a course (typically three or four cycles) of ovarian stimulation with IUI using oral agents (CC or letrozole). For those unsuccessful with ovarian stimulation and IUI treatments with oral agents, in vitro fertilization is recommended rather than ovarian stimulation and IUI with gonadotropins to reduce the risk of a multiple gestation.

Reproductive capability declines with continued attempts at conception such that, by 2 years, the approximate monthly fecundity rate is 3%-4%.
The first-line treatment of unexplained infertility is clomiphene citrate (CC) with intrauterine insemination. Letrozole, while not Food and Drug Administration approved for infertility treatment, has been shown in multiple studies to be equally effective as CC and to have a good safety profile. In a recent study, the cumulative live-birth rate over three cycles with CC and IUI, compared with expectant management was 31% versus 9%, respectively. Further, multiple studies failed to show a difference in pregnancy outcomes when comparing CC and IUI with letrozole and IUI.
It is vital to note that, for women who ovulate, studies do not support the use of CC without the addition of intrauterine insemination (IUI). The monthly fecundity rate of a cycle of CC without IUI is similar to natural conception attempts with urine LH timed intercourse, that is, without ovarian stimulation.
Recommendations (along with the level of evidence) from ASRM guidelines
- 1. Natural cycle, that is, without ovarian stimulation, timed with IUI is equivalent to expectant management (strong)
- 2. CC or letrozole with timed intercourse is no more effective than a natural cycle (good)
- 3. Pregnancy rates using gonadotropins with timed intercourse have not been shown to be superior to oral ovarian stimulating medications but risks multiple gestation (insufficient)
- 4. CC plus standard-dose gonadotropins results in higher pregnancy rates, there is good evidence for an increased risk of multiple gestation (fair)
- 5. Treatment with gonadotropins alone with IUI is superior to CC or letrozole with IUI; the risk of a multiple gestation rate remains significant (insufficient)
- 6. IUI can be performed between 0 and 36 hours following human chorionic gonadotropin trigger and performing one IUI in a cycle has equivalent success as two (fair)
- 7. Immediate IVF in women older than 38 years may be associated with a higher pregnancy rate and shorter time to pregnancy, compared with ovarian stimulation/IUI cycles before IVF (good)
Conclusion
It is recommended that couples with unexplained infertility initially undergo a course (typically three or four cycles) of ovarian stimulation with IUI using oral agents (CC or letrozole). For those unsuccessful with ovarian stimulation and IUI treatments with oral agents, in vitro fertilization is recommended rather than ovarian stimulation and IUI with gonadotropins to reduce the risk of a multiple gestation.

Physicians who care for women having difficulty conceiving must understand the devastation their patients feel while knowing how to define infertility, when (and when not) to advise an evaluation, and offer evidence-based treatment options. Analogous to a mother desiring an antibiotic prescription for her child’s common cold, infertility patients can be desperate for an evaluation and treatment, despite the lack of an indication. This month’s article addresses the diagnosis and management of unexplained infertility.
The chronological age of a woman is the leading prognostic factor for successful reproduction. The definition of infertility remains 1 year of an inability to conceive in a couple who have no demonstrable risk factors, such as ovulation dysfunction, prior infertility, or known male factor. In women less than age 30, monthly fecundity rates are between 20% and 37% during the first 3 months of trying to conceive. The chance of success increases to 80% after 1 year and 90% after 2 years of trying to conceive, according to the American Society of Reproductive Medicine. Nevertheless, following unsuccessful attempts at conception by a couple, the physician should offer an evaluation based on the woman’s age – 1 year for women less than age 35, 6 months for women aged 35-39, and 3 months for women aged 40 and older. Testing can be initiated earlier if there are predisposing factors impairing fertility.
The basic infertility evaluation consists of a thorough history of the couple, a review of medical records, and an assessment of ovulation, fallopian tube patency, and sperm parameters on analysis. In the interest of efficiency, given that couples are typically anxious, these three areas can be evaluated within 1 month. In years past, a diagnostic laparoscopy was considered the gold standard of necessity to provide the diagnosis of exclusion, that is, unexplained infertility. This surgical procedure has fallen out of favor given the low diagnostic yield in a woman with a normal hysterosalpingogram, pelvic ultrasound, and no risk for a pelvic factor; for example, prior abdominal myomectomy, bowel surgery, or strong suspicion for endometriosis based on symptoms including significant pelvic pain affecting activities of daily living.
Initial laboratory testing should be judiciously ordered by recommending only those that will affect management, that is, prenatal labs to assess immunity to rubella and varicella along with a baseline thyroid-stimulating hormone, CBC, blood type, and Rh and antibody screen. In a woman with monthly ovulatory menstrual cycles and no signs of hirsutism or galactorrhea, the clinical utility of obtaining follicle-stimulating hormone, luteinizing hormone (LH), estradiol, prolactin, total and free testosterone, and dehydroepiandrosterone lack evidence. Further, a random anti-Müllerian hormone (without prior chemotherapy, radiation, or ovarian surgery) lacks value as the natural pregnancy rate does not appear to be affected, although low AMH has been associated with an increased risk for miscarriage.
Although not typically screened, measles can cause significant complications in pregnancy including an increased risk of maternal hospitalization and pneumonia, as well as miscarriage, stillbirth, low birth weight, and increased risk of preterm delivery.
Education is an important tool to guide patients and begins with an explanation of urine LH timed intercourse. From the onset of the LH surge, the oocyte is released in 24-36 hours, i.e., the actual day of ovulation is estimated to be the day after the urine LH surge. The “fertile window” appears to be the 5 days before plus the day of ovulation but the highest chance of conception occurs within the 2 days before and including the day of ovulation.
Empiric treatment may be offered when no demonstrable etiology has been identified, lifestyle factors have been addressed (for example, elevated female body mass index, tobacco use by the couple), and medical conditions have been optimized.

Fast foods contain endocrine-disrupting chemicals
, such as chicken nuggets, hamburgers, and cheese pizza, new research suggests.
The first-of-its-kind study, which measured concentrations of chemicals such as phthalates in foods and gloves from U.S. fast food chains, is also the first to detect the plasticizer DEHT in fast foods.
“We knew from prior research that fast food consumption is linked to higher levels of phthalates in people’s bodies, but our study was novel because we actually collected these food items from fast food places and measured them,” said study author Lariah Edwards, PhD, a postdoctoral research scientist at the Milken Institute School of Public Health, George Washington University, Washington.
“Our research added an additional piece of information to the puzzle,” Dr. Edwards said in an interview.
A class of chemicals used in food packaging and food processing equipment, phthalates such as DEHP and DnBP, can leach out of these items and interfere with hormone production, Dr. Edwards said. They are linked with a wide variety of reproductive, developmental, brain, and immune effects, as well as with childhood obesity, asthma, cancer, and cardiovascular problems.
Meanwhile, nonphthalate or replacement plasticizers have been used in place of phthalates, some of which have been banned in certain products. But these plasticizers aren’t well studied, Dr. Edwards said, making the detection of DEHT in fast foods particularly concerning.
“There’s very limited research out there to understand the human health effects” of DEHT in food, she said, “so we’re being exposed before we understand what it’s doing to our health. It’s almost like we’re setting ourselves up for a big experiment.”
The study was recently published in the Journal of Exposure Science & Environmental Epidemiology .
Fast foods containing meat had highest concentrations of chemicals
Dr. Edwards and colleagues obtained 64 food samples, including hamburgers, fries, chicken nuggets, chicken burritos, and cheese pizza, as well as three pairs of unused gloves from six different fast food restaurants in San Antonio.
Using gas chromatography–mass spectrometry, they analyzed the samples for 11 chemicals, including eight phthalates and three replacement plasticizers.
The researchers detected 10 of the 11 chemicals in fast food samples: 81% of foods contained DnBP (di-n-butyl phthalate), and 70% contained DEHP (di(2-ethylhexyl phthalate)). Meanwhile 86% of samples contained replacement plasticizer DEHT (di(2-ethylhexyl terephthalate)).
Overall, fast food samples containing meat — including chicken nuggets, chicken burritos, and hamburgers — contained higher levels of these chemicals, Dr. Edwards noted.
“We know fast food is not the most nutritious, and now we’re seeing these chemicals in it we shouldn’t be exposed to,” she said.
The results also create implications for health equity, Dr. Edwards said, as Black people in the United States report eating more fast foods than other racial and ethnic groups for many reasons, such as longstanding residential segregation.
Many advocacy groups are pushing for stronger regulations on phthalates in foods, she said, and the study can be used to fuel those efforts.
“We’re hoping our findings help people understand what they’re eating and what’s in food,” Dr. Edwards said. “If they want to reduce exposure to phthalates in fast food, they can choose foods without meat in them. But not everyone has the option of reducing fast food consumption — personal choice is important, but policy is what’s going to protect us.”
Dr. Edwards noted that the research was limited by small sample sizes gathered in one U.S. city. Limitations in extraction methods also meant the researchers were able to detect chemicals in gloves only at high concentrations.
“That being said, I do think our results are fairly generalizable,” she added, “because the way fast foods are prepared at these restaurants is fairly consistent.”
The study was funded by the Passport Foundation, Forsythia Foundation, and Marisla Foundation. Dr. Edwards has reported no relevant financial relationships.

Evaluating phantom hCG and low-level hCG elevations in the nonpregnant patient
A human chorionic gonadotropin (hCG) test is commonly ordered by gynecologists prior to surgical procedures, in the workup of bleeding abnormalities, and in the follow-up of ectopic and molar pregnancies, to name a few indications. In doing so, occasionally clinicians will find themselves in the diagnostic dilemma of discovering an inexplicable low-level elevation in hCG, such as in a postmenopausal patient. This clinical picture can be confusing and can be concerning for conditions such as postmolar gestational trophoblastic neoplasia (GTN). However, there can be benign causes of this phenomenon.1 To prevent unnecessary worry, investigation of treatments is important. In fact, misdiagnosis and inappropriate treatment of benign, low-level hCG levels with unnecessary chemotherapy is problematic mismanagement of gestational trophoblastic disease (GTD), and a major cause of litigation.
Human chorionic gonadotropin is a glycoprotein hormone with two subunits (alpha and beta). It can come from multiple sources, including trophoblastic cells, malignant trophoblastic cells, the pituitary gland, and exogenous sources.1 Its alpha-subunit is identical to that of follicle stimulating hormone (FSH), luteinizing hormone (LH), and thyroid-stimulating hormone (TSH). Its beta-subunit is unique, though very similar to that of LH. The free hCG beta subunit can be produced by nontrophoblastic neoplasms. The gene for the beta subunit of hCG is in close proximity to the beta subunit of LH and increases in gonadotropin-releasing hormone (GnRH) in menopause can result in the stimulation of both genes. Understanding the sources of hCG-like glycoproteins and mechanisms for testing is important when considering possible causes for falsely elevated hCG.
Most commercially available serum hCG assays detect normal intact hCG and free beta subunits. They are typically sandwich assays utilizing antibody binding sites in which a solid-phase anti-hCG antibody to a specific hCG target is then mixed with the patient’s serum, trapping or binding the hCG, which is then treated with an indicator antibody. After being washed with the indicator or “capture” antibody, its relative (quantitative) levels can be measured.1
Urine hCG testing (such as urine pregnancy tests) work through capillary action, drawing the patient’s urine across absorbent pads before reaching a pad which contains anti-hCG antibodies (the detection zone) in the test line. These tests are less sensitive than serum tests, but many can detect hCG levels <15-20 mIU/mL.1
When ob.gyns. are asked to consult on or evaluate persistently low-level elevations of hCG in nonpregnant patients they should consider both malignant and nonmalignant etiologies. Malignant causes include GTN or quiescent GTD (e.g., after treatment of a molar pregnancy or GTN), choriocarcinoma (e.g., ovarian germ cell tumors), and nonchoriocarcinoma malignancies (such as cervical, pancreatic, breast, renal). Nonmalignant causes of hCG elevations in nonpregnant patients include pituitary hCG (in postmenopausal patients), exogenous hCG, and phantom hCG.
The first step in diagnostic workup is to perform a urine pregnancy test. Provided that the serum hCG level is > 20 mIU/mL, the urine HCG should be positive unless the cause of elevated levels is “phantom hCG” from heterophilic antibodies. When patients are exposed to animal antigens (such as in vaccines) they can develop antibodies such as human anti-mouse antibody. These antibodies have affinity to the binding antibodies used in many hCG sandwich assays and form a linkage between the solid phase antibody and the detection antibody creating a false-positive result. This false-positive test is only present in serum testing but not urine tests because the patient’s heterophilic antibodies are not excreted by the kidney and thus not available to create a false-positive result. An alternative method to make the diagnosis of phantom hCG is to request that the hCG testing be run at a different lab with a different assay (which may not react with the same affinity to the patient’s anti-animal heterophile antibodies), or to request that the lab perform serial dilutions. If phantom hCG from heterophile antibodies is at play, serial dilutions will result in a nonlinear dilution response.
If the patient’s urine hCG test is positive, then pregnancy should be ruled out with a transvaginal ultrasound. If negative, an ectopic pregnancy should still be considered (unless not medically plausible, such as in postmenopausal women or women who have undergone hysterectomy). In the absence of an intrauterine or ectopic pregnancy, a positive serum and urine pregnancy test could be from exogenous hCG, from malignancy or pituitary hCG. Use of exogenous hCG can be ruled out by taking a thorough history, with particular focus on asking about weight loss medications and muscle building therapies.
If pregnancy and exogenous hCG are ruled out, clinicians should assess for an occult hCG-secreting malignancy. The lab should be asked to measure the proportion of the free beta subunit of hCG, as this is typically what is secreted by malignancies. CT imaging of the chest, abdomen, and pelvis to search for an occult primary tumor should take place. If the patient has been recently treated for molar pregnancy or GTN, and serum hCG levels reside between 100 and 300 mIU/mL, quiescent GTD should be considered the diagnosis. Determination of the proportion of hyperglycosylated hCG to total hCG can help differentiate active choriocarcinoma from quiescent GTD. After restaging imaging has been done to confirm no measurable metastatic foci, observation can follow with monthly hCG measurements. The majority of these cases will eventually resolve without intervention within a year. Quiescent GTD and persistent low-level HCG in the absence of measurable GTN on imaging or symptoms does not require treatment with chemotherapy or hysterectomy, particularly in women who desire future fertility.2
Once occult malignancy has been ruled out, the remaining potential source of hCG is the pituitary gland. As mentioned earlier, hCG shares its morphology with TSH, LH, and FSH. This can result in cross reactivity and false positives. In the menopausal state, GnRH levels increase and thus so do pituitary LH and hCG levels. To confirm that the pituitary is the source of the low-level hCG levels, the provider should prescribe a course of hormonal treatment such as an oral contraceptive pill for a 2- to 3-month period. This should result in suppression of pituitary hCG, and serum hCG levels, as part of a negative feedback loop. Pituitary source of hCG is a benign condition, and, like quiescent GTD, phantom hCG or exogenous hCG does not require intervention.
Getting to the bottom of persistent low-level hCG elevations can be challenging. By following the step-wise algorithm listed here, clinicians can sequentially test for urine hCG, heterophilic antibodies, elevated free beta-subunit, occult malignancy, and pituitary hCG.

A human chorionic gonadotropin (hCG) test is commonly ordered by gynecologists prior to surgical procedures, in the workup of bleeding abnormalities, and in the follow-up of ectopic and molar pregnancies, to name a few indications. In doing so, occasionally clinicians will find themselves in the diagnostic dilemma of discovering an inexplicable low-level elevation in hCG, such as in a postmenopausal patient. This clinical picture can be confusing and can be concerning for conditions such as postmolar gestational trophoblastic neoplasia (GTN). However, there can be benign causes of this phenomenon.1 To prevent unnecessary worry, investigation of treatments is important. In fact, misdiagnosis and inappropriate treatment of benign, low-level hCG levels with unnecessary chemotherapy is problematic mismanagement of gestational trophoblastic disease (GTD), and a major cause of litigation.
Human chorionic gonadotropin is a glycoprotein hormone with two subunits (alpha and beta). It can come from multiple sources, including trophoblastic cells, malignant trophoblastic cells, the pituitary gland, and exogenous sources.1 Its alpha-subunit is identical to that of follicle stimulating hormone (FSH), luteinizing hormone (LH), and thyroid-stimulating hormone (TSH). Its beta-subunit is unique, though very similar to that of LH. The free hCG beta subunit can be produced by nontrophoblastic neoplasms. The gene for the beta subunit of hCG is in close proximity to the beta subunit of LH and increases in gonadotropin-releasing hormone (GnRH) in menopause can result in the stimulation of both genes. Understanding the sources of hCG-like glycoproteins and mechanisms for testing is important when considering possible causes for falsely elevated hCG.
Most commercially available serum hCG assays detect normal intact hCG and free beta subunits. They are typically sandwich assays utilizing antibody binding sites in which a solid-phase anti-hCG antibody to a specific hCG target is then mixed with the patient’s serum, trapping or binding the hCG, which is then treated with an indicator antibody. After being washed with the indicator or “capture” antibody, its relative (quantitative) levels can be measured.1
Urine hCG testing (such as urine pregnancy tests) work through capillary action, drawing the patient’s urine across absorbent pads before reaching a pad which contains anti-hCG antibodies (the detection zone) in the test line. These tests are less sensitive than serum tests, but many can detect hCG levels <15-20 mIU/mL.1
When ob.gyns. are asked to consult on or evaluate persistently low-level elevations of hCG in nonpregnant patients they should consider both malignant and nonmalignant etiologies. Malignant causes include GTN or quiescent GTD (e.g., after treatment of a molar pregnancy or GTN), choriocarcinoma (e.g., ovarian germ cell tumors), and nonchoriocarcinoma malignancies (such as cervical, pancreatic, breast, renal). Nonmalignant causes of hCG elevations in nonpregnant patients include pituitary hCG (in postmenopausal patients), exogenous hCG, and phantom hCG.
The first step in diagnostic workup is to perform a urine pregnancy test. Provided that the serum hCG level is > 20 mIU/mL, the urine HCG should be positive unless the cause of elevated levels is “phantom hCG” from heterophilic antibodies. When patients are exposed to animal antigens (such as in vaccines) they can develop antibodies such as human anti-mouse antibody. These antibodies have affinity to the binding antibodies used in many hCG sandwich assays and form a linkage between the solid phase antibody and the detection antibody creating a false-positive result. This false-positive test is only present in serum testing but not urine tests because the patient’s heterophilic antibodies are not excreted by the kidney and thus not available to create a false-positive result. An alternative method to make the diagnosis of phantom hCG is to request that the hCG testing be run at a different lab with a different assay (which may not react with the same affinity to the patient’s anti-animal heterophile antibodies), or to request that the lab perform serial dilutions. If phantom hCG from heterophile antibodies is at play, serial dilutions will result in a nonlinear dilution response.
If the patient’s urine hCG test is positive, then pregnancy should be ruled out with a transvaginal ultrasound. If negative, an ectopic pregnancy should still be considered (unless not medically plausible, such as in postmenopausal women or women who have undergone hysterectomy). In the absence of an intrauterine or ectopic pregnancy, a positive serum and urine pregnancy test could be from exogenous hCG, from malignancy or pituitary hCG. Use of exogenous hCG can be ruled out by taking a thorough history, with particular focus on asking about weight loss medications and muscle building therapies.
If pregnancy and exogenous hCG are ruled out, clinicians should assess for an occult hCG-secreting malignancy. The lab should be asked to measure the proportion of the free beta subunit of hCG, as this is typically what is secreted by malignancies. CT imaging of the chest, abdomen, and pelvis to search for an occult primary tumor should take place. If the patient has been recently treated for molar pregnancy or GTN, and serum hCG levels reside between 100 and 300 mIU/mL, quiescent GTD should be considered the diagnosis. Determination of the proportion of hyperglycosylated hCG to total hCG can help differentiate active choriocarcinoma from quiescent GTD. After restaging imaging has been done to confirm no measurable metastatic foci, observation can follow with monthly hCG measurements. The majority of these cases will eventually resolve without intervention within a year. Quiescent GTD and persistent low-level HCG in the absence of measurable GTN on imaging or symptoms does not require treatment with chemotherapy or hysterectomy, particularly in women who desire future fertility.2
Once occult malignancy has been ruled out, the remaining potential source of hCG is the pituitary gland. As mentioned earlier, hCG shares its morphology with TSH, LH, and FSH. This can result in cross reactivity and false positives. In the menopausal state, GnRH levels increase and thus so do pituitary LH and hCG levels. To confirm that the pituitary is the source of the low-level hCG levels, the provider should prescribe a course of hormonal treatment such as an oral contraceptive pill for a 2- to 3-month period. This should result in suppression of pituitary hCG, and serum hCG levels, as part of a negative feedback loop. Pituitary source of hCG is a benign condition, and, like quiescent GTD, phantom hCG or exogenous hCG does not require intervention.
Getting to the bottom of persistent low-level hCG elevations can be challenging. By following the step-wise algorithm listed here, clinicians can sequentially test for urine hCG, heterophilic antibodies, elevated free beta-subunit, occult malignancy, and pituitary hCG.

The male biological clock – How to tell the time
For decades, we have recognized the age-related natural decline in female fecundity (the ability to reproduce) after the age of 30 (Maturitas 1988;[Suppl]1:15-22). Advanced maternal age (AMA) has also been demonstrated to increase miscarriage and pregnancies with chromosomal abnormalities, presumably from the increased rate of oocyte aneuploidy. There has been a sixfold increase in the rate of first birth in women aged 35-39 years (NCHS Data Brief 2014;152:1-8). Consequently, over the last decade, women, often before they reach AMA, have turned to elective oocyte cryopreservation for fertility preservation.
Ovarian aging
Ovarian aging occurs through the decline in quality and quantity of oocytes. The former is a reflection of the woman’s chronologic age. Markers of female ovarian aging have been utilized, for the past 3 decades, most commonly by basal follicle stimulating hormone. Currently, to assess the quantity of ovarian follicles, antimüllerian hormone (AMH) and transvaginal ultrasound for ovarian antral follicle count (AFC) are the most accurate indicators (J Clin Endocrinol Metab 2004:89:2977-81). While ovarian age testing, particularly AMH, has been widely used to assess a woman’s “fertility potential,” it does not reflect her natural fecundity. In a prospective cohort study, AMH levels (ng/mL) divided into < 0.7, 0.7-8.4, and > 8.4, did not affect natural conception in women aged 30-44 who were divided into the categories of <35, 35-37, or 38-44 years (JAMA 2017;318:1367-76). Although AMH does reduce success with IVF, its main value is the inverse correlation when prescribing gonadotropin dosage for controlled ovarian stimulation.
Despite the familiarity with ovarian aging effects on fertility, the male biological clock remains less studied and understood. Over the last 4 decades, paternal age has increased an average of 3.5 years presumably due to delayed child rearing from professional or personal reasons, improved contraception as well as increased divorce, remarriage, and life expectancy (Hum Reprod. 2017;32:2110-6). Nevertheless, we have little data to definitively counsel men on the effects of advanced paternal age (APA) and no consensus on an actual defined age of designation. This month’s article will summarize the current literature on male age and its impact on fertility.
Testicular aging
Men older than 45 years require approximately five times longer to achieve a pregnancy as men less than 25 after adjustment for female age (Fertil Steril. 2003;79:1520-7). The most likely parameter to assess male fertility, other than pregnancy rates, would be the sperm. Sperm counts, beginning at age 41, may decline but concentrations have been shown to increase in older men apparently because of declining semen volume (Ageing Res Rev. 2015;19:22-33). Sperm motility, but not morphology, also declines while genetic alterations of sperm increase with age. The issue of chromosomal abnormalities in sperm from men of advanced age appears to be similar to that in the oocytes of women with AMA. Consequently, both sexes may contribute to embryo aneuploidy resulting in declining fertility and increasing miscarriage.
For all ages, studies have suggested that elevated male body mass index as well as alcohol consumption and cigarette smoking, including e-cigarettes, can lead to impaired sperm production (Hum Reprod Update 2013;19:221-31).
Fertility treatment outcomes
A mainstay of fertility treatment, particularly in men with mild to moderate impairments in semen parameters, is ovulation induction with intrauterine insemination. Male age has been shown to be a significant indicator for pregnancy rates, including those with normal semen parameters (J Obstet Gynaecol. 2011;31:420-3). Men above age 45 contributed to lower pregnancy rates and higher miscarriages during IUI treatment cycles (Reprod BioMed Online 2008;17:392-7).
During IVF cycles, the sperm of men with APA often undergo ICSI (intracytoplasmic sperm injection) due to higher fertilization rates compared with standard insemination. However, APA sperm appear to have lower fertilization rates and decreased embryo development to the blastocyst stage during cycles using donor oocytes, although pregnancy outcomes are inconsistent (Trans Androl Urol. 2019;8[Suppl 1]:S22-S30; Fertil Steril. 2008;90:97-103).
Perinatal and children’s health
The offspring from APA men appear to have higher rates of stillbirth, low birth weight, and preterm birth, as well as birth defects. Men older than 40-45 years have twice the risk of an autistic child and three times the risk of schizophrenia in their offspring (Transl Psychiatry 2017;7:e1019; Am J Psychiatry 2002;159:1528-33).
Conclusions
Most of the literature supports negative effects on sperm and reproduction from men with APA. The challenge in deciphering the true role of APA on fertility is that the partner is often of AMA. A consideration to avoid this effect would be sperm cryopreservation at a younger age, similar to the common trend among women. Preimplantation genetic testing of embryos from men with APA is also a potential option to reduce miscarriage and avoid a chromosomally abnormal pregnancy. Ethicists have pondered the impact of APA on parenthood and the detrimental effect of early paternal death on the child. Nevertheless, the effect of APA in reproduction is a vital area to study with the same fervor as AMA (Fertil Steril 2009;92:1772-5).

Low androgen in kidney recipients tied to diabetes
Low androgen levels appear to be linked to the development of posttransplantation diabetes mellitus (PTDM) in male kidney transplant recipients, new research suggests.
Among 243 men who did not have diabetes prior to undergoing kidney transplantation, levels of both dihydrotestosterone (DHT) and testosterone were inversely related to the risk for developing diabetes the next 5 years.
“These results suggest that androgen insufficiency could play a role in the frequent deterioration of the glucose metabolism after kidney transplantation,” Suzanne P. Stam and colleagues wrote in Diabetes Care.
However, “our study has unfortunately no direct clinical findings as it was of an observational nature,” Ms. Stam told this news organization. “As a result, we can say that we have observed an association and have not established a causal relationship. So based on our study alone there is not a reason to start screening for low androgen values.”
Previous data have suggested that failure of pancreatic beta cell secretion of insulin plays a role in PTDM. In addition, DHT appears to act on the androgen receptor in pancreatic beta cells to enhance insulin secretion, while testosterone deficiency has been shown to play a role in the development of type 2 diabetes in aging males and in men receiving androgen-deprivation therapy. And, randomized clinical trials have found favorable metabolic effects of testosterone replacement therapy in hypogonadal men with type 2 diabetes.
The current post hoc analysis of a prospective single-center cohort study is the first longitudinal epidemiological investigation of the role of androgens in PTDM in kidney transplant recipients. The subjects, all men, had functioning grafts for at least a year posttransplantation. Androgen levels were assessed by liquid chromatography–tandem mass spectrometry.
At a median follow-up duration of 5.3 years, 28 (11.5%) of the men had developed PTDM. By DHT tertile, the proportions developing diabetes were 19% (15) for the lowest, 12% (10) for the middle, and 4% (3) for men with the highest DHT tertile (P = .008). A similar relationship was seen with tertiles of testosterone, with 17% (14), 14% (11), and 4% (3) developing diabetes in the lowest, middle, and highest tertiles, respectively (P = .01).
In unadjusted analysis, every doubling of DHT was linked to a 27% increased risk for PTDM (P < .001). The association remained significant after adjustments for age, estimated glomerular filtration rate, time between transplantation and baseline, body mass index, high sensitivity C-reactive protein, medication use, and baseline hemoglobin A1c (all P < .001). Similar results were found with total testosterone.
Ms. Stam, of the division of nephrology at the University Medical Center Groningen, the Netherlands, noted in an interview that, in the Netherlands, about 15% of those with kidney failure have preexisting diabetes, compared with about 50% in other western countries, including the United States.
She said that her team is currently working on a study to investigate the association between androgens and the development of PTDM in female kidney transplant recipients.
The study was funded by the TransplantLines Food and Nutrition Biobank and Cohort Study, Top Institute Food and Nutrition, and partly by the European Union’s Horizon 2020 research and innovation program. Ms. Stam and the other authors have no further disclosures.

The association remained significant after adjustments for age, estimated glomerular filtration rate, time between transplantation and baseline, body mass index, high sensitivity C-reactive protein, medication use, and baseline hemoglobin A1c (all P < .001). Similar results were found with total testosterone.
Ms. Stam, of the division of nephrology at the University Medical Center Groningen, the Netherlands, noted in an interview that, in the Netherlands, about 15% of those with kidney failure have preexisting diabetes, compared with about 50% in other western countries, including the United States.
She said that her team is currently working on a study to investigate the association between androgens and the development of PTDM in female kidney transplant recipients.
The study was funded by the TransplantLines Food and Nutrition Biobank and Cohort Study, Top Institute Food and Nutrition, and partly by the European Union’s Horizon 2020 research and innovation program. Ms. Stam and the other authors have no further disclosures.

COVID-19 pandemic affects menstrual cycles, presenting challenges for conception
A survey of more than 12,000 women of reproductive age found that one in three had experienced changes to their menstrual cycles and symptoms during the COVID-19 pandemic. Noticeably higher stress levels than prepandemic benchmarks could be affecting menstruation.
This has implications for women trying to conceive or struggling with infertility, said Shannon M. Malloy, a research and data associate with Ovia Health, a women’s and family health technology company in Boston. Ms. Malloy presented this study at the American Society of Reproductive Medicine’s 2021 meeting.
COVID-19 has introduced new psychosocial, interpersonal, and environmental stressors. The pandemic is “one of the most stressful, collectively experienced disasters modern society has ever seen,” said Ms. Malloy. Once imagined as an explicit event in time, COVID-19 has ingrained itself into daily life for the foreseeable future.
Research has shown that chronic, long-term stress produces high cortisol levels, which can alter endocrinology and regulation of menstrual cycles. This can make family building even more challenging, said Ms. Malloy. Physicians and other providers have always taken stress into account when managing patients, but never at this level of chronic, episodic stress, she said.
Survey examines impact on ART
Ovia Health decided to investigate the relationship between perceived stress and menstrual cycle and symptom changes during the COVID-19 pandemic, to see how it might affect assisted reproductive technology (ART).
From March 2020 to April 2021, users of Ovia Health’s Fertility mobile application in the United States took part in a survey. Items captured changes in menstruation pattern and symptomatology and included the Perceived Stress Scale 4-item version (PSS-4). A paired t-test evaluated differences between groups (menstrual changes versus no menstrual changes). The survey asked participants what changes they noticed in their menstrual cycle and why they thought cycle patterns or symptoms changed.
One-third report changes in cycle, symptoms
Among 12,302 respondents, 1 in 3 (36%) reported changes in cycle or symptoms. Eighty-seven percent said that their cycle started early or late. Twenty-nine percent reported stronger symptoms during menstruation such as low back pain, cramping, or discharge changes, and 27% said bleeding was heavier during periods.
These results are similar to other studies investigating the affect of episodic stress on menstruation, said Ms. Malloy.
Those who reported menstrual cycle or symptom changes scored higher on average on the PSS-4 compared with those who didn’t report any changes (8.5 v. 8.3, respectively, P < .05). PSS-4 scores across the board were notably higher in all respondents, regardless of cycle/symptom irregularity, compared with prepandemic benchmarking in similar populations.
Slightly more than half (55%) thought stress contributed to their menstrual cycle pattern and/or symptom changes, whereas 33% pointed to changes in mental health, such as depression or anxiety. “Interestingly, many users believed the COVID-19 vaccine impacted their menstrual cycle symptom changes,” said Ms. Malloy.
No definitive link between vaccine, menstruation
While known side effects of the vaccine include sore arm, fever, fatigue, and myalgia, some women have reported changes in their menstrual cycle, Mark P. Trolice, MD, professor of obstetrics and gynecology at the University of Central Florida and director of the IVF Center in Orlando, said in an interview.
“Vaccination reaction from the immune response rather than the vaccine may be the implicating factor,” said Dr. Trolice, who was not involved in the study.
Currently, there’s no direct link between the vaccine and subsequent effects on menstruation, he continued. “Most women experience resumption of normal intervals 1 month following vaccination. Further, there is no credible evidence that links the vaccine to infertility.
“Nevertheless, research in this area is vital and underway,” he added.
Physicians can help with stress
Menstrual cycle disruption is especially frustrating for women trying to build a family, said Ms. Malloy. Providers may be observing more menstrual irregularity in their patient populations, and seeing more patients struggle to conceive on their own, turning to ART.
Providers can’t make COVID-19 go away, but they could help patients by doing a better job of integrating mental health screening, connecting patients to treatments that optimize conception and fertility treatment outcomes, said Ms. Malloy.
The survey was limited in that its questions didn’t consider proper diagnostic criteria for irregularity, versus self-reported changes. But it does highlight the need for more research on the pandemic’s affect on menstruation and the vaccine on menstruation, said Ms. Malloy. “The National Institutes of Health in August committed $1.6 million to explore this connection. We’re looking forward to seeing what their results are.”

Patients seeking infertility care report infrequent counseling on weight loss
Physicians could be doing a better job of counseling patients with obesity and overweight on weight loss and fertility. A study of 48 women seeking infertility care at a large academic center found that less than half received advice on weight loss from their primary ob.gyn. prior to referral for infertility treatment.
Patients are thinking about this – many attempt to lose weight independently of support from their health care providers, said lead study author Margaret R. O’Neill, MD, a resident at the University of Massachusetts Medical Center in Worcester. Dr. O’Neill discussed these results at the American Society of Reproductive Medicine’s 2021 meeting.
Nearly half of all U.S. women of reproductive age have overweight or obesity, with a body mass index of >25 kg/m2. Menstrual irregularity, ovulatory dysfunction, reduced fecundity, and lower efficacy of infertility treatment are some of the consequences of obesity on fertility, said Dr. O’Neill. Obesity also affects the health of expectant mothers and fetuses, increasing the likelihood of gestational diabetes, preterm delivery, and preeclampsia, and increased incidence of fetal anomalies.
“Unfortunately, even though the prevalence of obesity has been increasing substantially in our country, there’s not excellent rates of this being addressed by physicians,” said Dr. O’Neill. BMI is often left out of documentation and rates of referrals to weight loss specialists are also low.
Conversations have been taking place about IVF centers instituting different BMI cutoffs for certain types of assisted reproductive technology, she noted.
Dr. O’Neill and her colleagues undertook a survey to see what advice community providers were dispensing about weight management on fertility.
Infertility specialists offer the most guidance
The prospective study included 48 nonpregnant women of reproductive age women presenting for IVF who needed an anesthesia consultation because of elevated BMI (> 35) prior to initiation of IVF. Mean age was 36 years and mean BMI was 38.5. More than 70% of the patients were White and they were predominantly English speakers.
All participants had attempted weight loss, including an attempt in the last year, and 93.8% reported trying to lose weight in the last year. On average, patients weighed about 20 pounds less than their heaviest adult weight. Nineteen percent of the participants were at their heaviest adult weight.
While 60% said they’d received weight loss/infertility counseling by any health care provider, just 41.7% reported that their primary ob.gyn. counseled them about weight loss before referring them for treatment. Infertility specialists seem to provide the most assistance: Nearly 70% of the respondents said they’ve been counseled by these providers.
Women with a higher-than-average BMI (39) were more likely to report a referral to weight loss counseling compared with women not referred (37.9, P = .2).
Investigators also asked patients about their knowledge of obesity and its relationship to other health conditions. About 90% understood that infertility and excess weight were related. Overall, they were less sure about the link between obesity and still birth, breast cancer, and birth defects. Only 37% were able to identify a normal BMI range.
Avoiding a touchy subject
BMI is a highly sensitive area for many women, despite its detrimental effect on fertility, Mark P. Trolice, MD, professor of obstetrics and gynecology at the University of Central Florida and director of the IVF Center in Orlando, said in an interview.
“By the time their journey has led them to an infertility specialist, most women are very anxious to begin treatment,” said Dr. Trolice, who was not involved in the survey. These patients, however, could interpret any medical advice to achieve a more optimal BMI and healthier lifestyle as a negative judgment that could delay their goal of having a healthy child, he said.
Physicians in turn may avoid these conversations because they don’t want to encourage the ire of patients and/or risk a negative online rating review, he added.
Don’t say ‘just lose weight’
When asked what type of counseling works best, many said that nonspecific recommendations such as “you need to lose weight” or “exercise more” were the least helpful. Targeted advice such as “avoid eating at night and take walks every day,” works more effectively. “Any kind of referral to a bariatrics team or weight loss program was seen as helpful by patients,” said Dr. O’Neill.
Suggestions that considered the difficulty of this process, such as seeking therapy, were also helpful. “Patients appreciated empathy, compassion, and encouragement” from their physicians, she said.
The role of physicians in weight loss
Physicians can make a difference. Studies show that patients who received weight loss counseling were more likely to attempt weight loss and report clinically significant weight loss.
The American College of Obstetricians and Gynecologists and ASRM recommend counseling patients with overweight and obesity to lose weight before getting pregnant. A modest weight loss of 10% is associated with improved ovulatory function and higher pregnancy rates, said Dr. O’Neill.
“Appropriately, the infertility specialist should strongly recommend [that women who are obese] obtain a more optimal BMI prior to fertility treatment. While there is no guarantee of decreased infertility and decreased pregnancy complications following weight loss, a lower BMI improves outcomes,” said Dr. Trolice.
Future research should address the fertility outcomes of women who have been counseled by their providers to lose weight and the most effective method of counseling, noted Dr. O’Neill. “We have to find the best ways to address this at each fertility institution.”
The study had limited generalizability because of its narrow patient population and regional differences in access to insurance and weight loss specialists. COVID-19 also reduced the sample size, said Dr. O’Neill. She noted that patient perceptions might not equate with actual counseling delivered.

Bone risk: Is time since menopause a better predictor than age?
Although early menopause is linked to increased risks in bone loss and fracture, new research indicates that, even among the majority of women who have menopause after age 45, the time since the final menstrual period can be a stronger predictor than chronological age for key risks in bone health and fracture.
In a large longitudinal cohort, the number of years since a woman’s final menstrual period specifically showed a stronger association with femoral neck bone mineral density (BMD) than chronological age, while an earlier age at menopause – even among those over 45 years, was linked to an increased risk of fracture.
“Most of our clinical tools to predict osteoporosis-related outcomes use chronological age,” first author Albert Shieh, MD, told this news organization.
“Our findings suggest that more research should be done to examine whether ovarian age (time since final menstrual period) should be used in these tools as well.”
An increased focus on the significance of age at the time of the final menstrual period, compared with chronological age, has gained interest in risk assessment because of the known acceleration in the decline of BMD that occurs 1 year prior to the final menstrual period and continues at a rapid pace for 3 years afterwards before slowing.
To further investigate the association with BMD, Dr. Shieh, an endocrinologist specializing in osteoporosis at the University of California, Los Angeles, and his colleagues turned to data from the Study of Women’s Health Across the Nation (SWAN), a longitudinal cohort study of ambulatory women with pre- or early perimenopausal baseline data and 15 annual follow-up assessments.
Outcomes regarding postmenopausal lumbar spine (LS) or femoral neck (FN) BMD were evaluated in 1,038 women, while the time to fracture in relation to the final menstrual period was separately evaluated in 1,554 women.
In both cohorts, the women had a known final menstrual period at age 45 or older, and on average, their final menstrual period occurred at age 52.
After a multivariate adjustment for age, body mass index, and various other factors, they found that each additional year after a woman’s final menstrual period was associated with a significant (0.006 g/cm2) reduction in postmenopausal lumbar spine BMD and a 0.004 g/cm2 reduction femoral neck BMD (both P < .0001).
Conversely, chronological age was not associated with a change in femoral neck BMD when evaluated independently of years since the final menstrual period, the researchers reported in the Journal of Clinical Endocrinology and Metabolism.
Regarding lumbar spine BMD, chronological age was unexpectedly associated not just with change, but in fact with increases in lumbar spine BMD (P < .0001 per year). However, the authors speculate the change “is likely a reflection of age-associated degenerative changes causing false elevations in BMD measured by dual-energy x-ray absorptiometry.”
Fracture risk with earlier menopause
In terms of the fracture risk analysis, despite the women all being aged 45 or older, earlier age at menopause was still tied to an increased risk of incident fracture, with a 5% increase in risk for each earlier year in age at the time of the final menstrual period (P = .02).
Compared with women who had their final menstrual period at age 55, for instance, those who finished menstruating at age 47 had a 6.3% greater 20-year cumulative fracture risk, the authors note.
While previous findings from the Malmo Perimenopausal Study showed menopause prior to the age of 47 to be associated with an 83% and 59% greater risk of densitometric osteoporosis and fracture, respectively, by age 77, the authors note that the new study is unique in including only women who had a final menstrual period over the age of 45, therefore reducing the potential confounding of data on women under 45.
The new results “add to a growing body of literature suggesting that the endocrine changes that occur during the menopause transition trigger a pathophysiologic cascade that leads to organ dysfunction,” the authors note.
In terms of implications in risk assessment, “future studies should examine whether years since the final menstrual period predicts major osteoporotic fractures and hip fractures, specifically, and, if so, whether replacing chronological age with years since the final menstrual period improves the performance of clinical prediction tools, such as FRAX [Fracture Risk Assessment Tool],” they add.
Addition to guidelines?
Commenting on the findings, Peter Ebeling, MD, the current president of the American Society of Bone and Mineral Research, noted that the study importantly “confirms what we had previously anticipated, that in women with menopause who are 45 years of age or older a lower age of final menstrual period is associated with lower spine and hip BMD and more fractures.”
“We had already known this for women with premature ovarian insufficiency or an early menopause, and this extends the observation to the vast majority of women – more than 90% – with a normal menopause age,” said Dr. Ebeling, professor of medicine at Monash Health, Monash University, in Melbourne.
Despite the known importance of the time since final menstrual period, guidelines still focus on age in terms of chronology, rather than biology, emphasizing the risk among women over 50, in general, rather than the time since the last menstrual period, he noted.
“There is an important difference [between those two], as shown by this study,” he said. “Guidelines could be easily adapted to reflect this.”
Specifically, the association between lower age of final menstrual period and lower spine and hip BMD and more fractures requires “more formal assessment to determine whether adding age of final menstrual period to existing fracture risk calculator tools, like FRAX, can improve absolute fracture risk prediction,” Dr. Ebeling noted.

Although early menopause is linked to increased risks in bone loss and fracture, new research indicates that, even among the majority of women who have menopause after age 45, the time since the final menstrual period can be a stronger predictor than chronological age for key risks in bone health and fracture.
In a large longitudinal cohort, the number of years since a woman’s final menstrual period specifically showed a stronger association with femoral neck bone mineral density (BMD) than chronological age, while an earlier age at menopause – even among those over 45 years, was linked to an increased risk of fracture.
“Most of our clinical tools to predict osteoporosis-related outcomes use chronological age,” first author Albert Shieh, MD, told this news organization.
“Our findings suggest that more research should be done to examine whether ovarian age (time since final menstrual period) should be used in these tools as well.”
An increased focus on the significance of age at the time of the final menstrual period, compared with chronological age, has gained interest in risk assessment because of the known acceleration in the decline of BMD that occurs 1 year prior to the final menstrual period and continues at a rapid pace for 3 years afterwards before slowing.
To further investigate the association with BMD, Dr. Shieh, an endocrinologist specializing in osteoporosis at the University of California, Los Angeles, and his colleagues turned to data from the Study of Women’s Health Across the Nation (SWAN), a longitudinal cohort study of ambulatory women with pre- or early perimenopausal baseline data and 15 annual follow-up assessments.
Outcomes regarding postmenopausal lumbar spine (LS) or femoral neck (FN) BMD were evaluated in 1,038 women, while the time to fracture in relation to the final menstrual period was separately evaluated in 1,554 women.
In both cohorts, the women had a known final menstrual period at age 45 or older, and on average, their final menstrual period occurred at age 52.
After a multivariate adjustment for age, body mass index, and various other factors, they found that each additional year after a woman’s final menstrual period was associated with a significant (0.006 g/cm2) reduction in postmenopausal lumbar spine BMD and a 0.004 g/cm2 reduction femoral neck BMD (both P < .0001).
Conversely, chronological age was not associated with a change in femoral neck BMD when evaluated independently of years since the final menstrual period, the researchers reported in the Journal of Clinical Endocrinology and Metabolism.
Regarding lumbar spine BMD, chronological age was unexpectedly associated not just with change, but in fact with increases in lumbar spine BMD (P < .0001 per year). However, the authors speculate the change “is likely a reflection of age-associated degenerative changes causing false elevations in BMD measured by dual-energy x-ray absorptiometry.”
