RESUMO
PURPOSE: To evaluate whether the type of frozen embryo transfer (FET) regimen - ovulation-induced regimens vs. hormone replacement therapy regimens (HRT) - is associated with live birth rates and the risk of hypertensive diseases of pregnancy (HDP) in women with polycystic ovary syndrome (PCOS). METHODS: All studies in PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov were searched using a combination of MeSH terms and keywords. Inclusion criteria included studies on women with a diagnosis of PCOS, utilization of FET, and reporting of pregnancy and/or obstetric outcomes. Studies were excluded if they were case series or conference abstracts or used other FET regimens. A random effects meta-analysis was performed. Primary outcomes include relative risk (RR) of live birth and HDP. RESULTS: Eleven studies were included in the meta-analysis for the final review. Ovulation-induced regimens were associated with a higher live birth rate (8 studies, RR 1.14 [95% CI 1.08, 1.21]) compared to HRT regimens. The risk of HDP (3 studies RR 0.78 [95% CI 0.53, 1.15]) was not significantly different. Ovulation-induced regimens were associated with a lower miscarriage rate (9 studies, RR 0.67 [95% CI 0.59-0.76]). Rates of clinical pregnancy (10 studies, RR 1.05 [95% CI 0.99, 1.11]) and ectopic pregnancy (7 studies, RR 1.40 [95% CI 0.84, 2.33]), were not significantly different. CONCLUSION: This SR/MA demonstrates that for women with PCOS, ovulation-induced FET regimens are associated with higher rates of live birth and lower rates of miscarriage compared to HRT regimens.
RESUMO
PURPOSE: To determine the recurrence risk and risk factors for monozygotic splitting after elective single-embryo transfers (eSET). METHODS: A retrospective cohort study was performed investigating 65,664 eSET cycles that resulted in a clinical pregnancy as reported in the Society for Assisted Reproductive Technology (SART) Clinical Outcomes Reporting System (CORS) between 2004 and 2017. Monozygosity was defined as more than one fetal heart tone by the first-trimester ultrasound and concordant sex at live birth. The primary outcome was recurrence risk, with recurrence defined as one patient having two or more cycles of eSET resulting in monozygotic multiples. The secondary objective was to identify factors associated with smonozygotic splitting, using a multivariable logistic regression model and a stepwise purposeful model selection. RESULTS: There were 1355 (2.05%) pregnancies that resulted in two or more fetal heart tones after SET, including 840 monozygotic twins and triplets at birth. Recurrence occurred in two cases-0.0001% of patients with multiple eSET cycles. One case resulted from embryos created from a single cohort with intracytoplasmic sperm injection (ICSI), assisted hatching (AH), and blastocyst transfers. The second case resulted from donor egg embryos with ICSI and blastocyst transfers. Risk factors associated with monozygotic live birth were blastocyst transfer (OR 1.23, 95% CI 1.04-1.47, P = 0.0176) and AH (OR 1.23, 95% CI 1.05-1.44, P = 0.0081). CONCLUSION: Recurrence of monozygotic live births in eSET was very rare. Blastocyst transfer and AH were confirmed to be risk factors for monozygotic live births, while ICSI, PGT, and FET do not appear to be associated.

BACKGROUND: Antimüllerian hormone is produced by small antral follicles and reflects ovarian reserve. Obesity is associated with lower serum antimüllerian hormone, but it is unclear whether lower levels of antimüllerian hormone in women with obesity reflect lower ovarian reserve. OBJECTIVE: To determine whether lower antimüllerian hormone in women with obesity undergoing in vitro fertilization is associated with oocyte yield and live-birth rate. MATERIALS AND METHODS: Retrospective cohort from the Society for Assisted Reproductive Technology Clinic Outcome Reporting System database of 13,316 women with obesity and 16,579 women with normal body mass index undergoing their first autologous in vitro fertilization with fresh transfers between 2012 and 2014. Normal body mass index was defined as body mass index 18.5-24.9 kg/m2, and obesity was defined as body mass index ≥30 kg/m2. Subjects with obesity were stratified as those with class 1 obesity (body mass index, 30.0-34.9 kg/m2), class 2 obesity (body mass index, 35.0-39.9 kg/m2), and class 3 obesity (body mass index, ≥40 kg/m2) based on the World Health Organization body mass index guidelines. Antimüllerian hormone levels were stratified as normal (>1.1 ng/mL), low (0.16-1-1 ng/mL), and undetectable (≤0.16 ng/mL). Multivariable modeling was used to assess oocyte yield using linear regression with a logarithmic transformation and odds of live birth using logistic regression. RESULTS: Women with obesity were older (36.0 ± 4.8 vs 35.5 ± 4.8, P < .001), had lower antimüllerian hormone (1.8 ± 2.0 ng/mL vs 2.1 ± 2.0 ng/mL, P < .001), and had fewer oocytes retrieved (11.9 ± 7.3 vs 12.8 ± 7.7, P < .001) than women with normal body mass index. Lower oocyte yield was observed among women with obesity and normal antimüllerian hormone levels compared to women with normal body mass index and normal antimüllerian hormone levels (13.6 ± 7.3 vs 15.8 ± 8.1, P < .001). No difference in oocyte yield was observed among women with obesity and low antimüllerian hormone levels (P = .58) and undetectabl antimüllerian hormone (P = .11) compared to women with normal BMI and similar antimüllerian hormone levels. Among women with a body mass index ≥30 kg/m2, antimüllerian hormone levels were associated with the number of oocytes retrieved (ß = 0.069; standard error, 0.005; P < .001) but not live-birth rate (odds ratio, 0.98; 95% confidence interval, 0.93-1.04, P = .57). CONCLUSION: Lower antimüllerian hormone in infertile women with obesity appears to reflect lower ovarian reserve, as antimüllerian hormone is associated with lower oocyte yield. Despite lower oocyte yield, lower antimüllerian hormone was not associated with lower live-birth rate among women with obesity.

STUDY QUESTION: Among infertile women undergoing ovarian stimulation, is allostatic load (AL), a measure of chronic physiological stress, associated with subsequent fertility and pregnancy outcomes? SUMMARY ANSWER: AL at baseline was not associated with conception, spontaneous abortion or live birth, however, it was significantly associated with increased odds of pre-eclampsia and preterm birth among women who had a live birth in the study. WHAT IS KNOWN ALREADY: Several studies have linked AL during pregnancy to adverse outcomes including preterm birth and pre-eclampsia, hypothesizing that it may contribute to well-documented disparities in pregnancy and birth outcomes. However, AL biomarkers change over the course of pregnancy, raising questions as to whether gestational AL assessment is a valid measure of cumulative physiologic stress starting long before pregnancy. To better understand how AL may impact reproductive outcomes, AL measurement in the non-pregnant state (i.e. prior to conception) is needed. STUDY DESIGN, SIZE, DURATION: A secondary data analysis based on data from 836 women who participated in Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS), a multi-center, randomized clinical trial of ovarian stimulation conducted from 2011 to 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS: Ovulatory women with unexplained infertility (ages 18-40) were enrolled and at baseline, biological and anthropometric measures were collected. AL scores were calculated as a composite of the following baseline variables determined a priori: BMI, waist-to-hip ratio, systolic blood pressure, diastolic blood pressure, dehydroepiandrosterone sulfate, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, C-reactive protein and HOMA score. Participants received ovarian stimulation for up to four cycles and if they conceived, were followed throughout pregnancy. We fit multi-variable logistic regression models examining AL (one-tailed and two-tailed) in relation to the following reproductive outcomes: conception, spontaneous abortion, live birth, pre-eclampsia, preterm birth and low birthweight. MAIN RESULTS AND THE ROLE OF CHANCE: Adjusting for covariates, a unit increase in two-tailed AL score was associated with 62% increased odds of pre-eclampsia (OR: 1.62, 95% CI: 1.14, 2.38) 44% increased odds of preterm birth (OR: 1.44, 95% CI: 1.02, 2.08), and 39% increased odds of low birthweight (OR: 1.39, 95% CI: 0.99, 1.97). The relationship between AL and preterm birth was mediated by pre-eclampsia (P = 0.0003). In one-tailed AL analyses, associations were similar, but slightly attenuated. AL was not associated with fertility outcomes (conception, spontaneous abortion, live birth). LIMITATIONS, REASONS FOR CAUTION: Results may not be generalizable to fertile women who conceive naturally or women with other types of infertility. Comparisons to previous, related work are difficult because variables included in AL composite measures vary across studies. AL may be indicative of overall poor health, rather than being specific to chronic physiological stress. WIDER IMPLICATIONS OF THE FINDINGS: Our results suggest that chronic physiological stress may not impact success of ovarian stimulation, however, they confirm and extend previous work suggesting that AL is associated with adverse pregnancy outcomes. Physiological dysregulation due to chronic stress has been proposed as a possible mechanism underlying disparities in birth outcomes, which are currently poorly understood. Assessing biomarkers of physiological dysregulation pre-conception or in early pregnancy, may help to identify women at risk of adverse pregnancy outcomes, particularly pre-eclampsia.

Once unimaginable, fertility management is now a nationally established part of cancer care in institutions, from academic centers to community hospitals to private practices. Over the last two decades, advances in medicine and reproductive science have made it possible for men, women and children to be connected with an oncofertility specialist or offered fertility preservation soon after a cancer diagnosis. The Oncofertility Consortium's National Physicians Cooperative is a large-scale effort to engage physicians across disciplines - oncology, urology, obstetrics and gynecology, reproductive endocrinology, and behavioral health - in clinical and research activities to enable significant progress in providing fertility preservation options to children and adults. Here, we review the structure and function of the National Physicians Cooperative and identify next steps.

PURPOSE: To compare saline infusion sonohysterography (SIS) versus hysterosalpingogram (HSG) for confirmation of tubal patency. METHODS: Secondary analysis of a randomized controlled trial, Pregnancy in Polycystic Ovary Syndrome II (PPCOS II). Seven hundred fifty infertile women (18-40 years old) with polycystic ovary syndrome (PCOS) were randomized to up to 5 cycles of letrozole or clomiphene citrate. Prior to enrollment, tubal patency was determined by HSG, the presence of free fluid in the pelvis on SIS, laparoscopy, or recent intrauterine pregnancy. Logistic regression was conducted in patients who ovulated with clinical pregnancy as the outcome and HSG or SIS as the key independent variable. RESULTS: Among women who ovulated, 414 (66.9%) had tubal patency confirmed by SIS and 187 (30.2%) had at least one tube patent on HSG. Multivariable analysis indicated that choice of HSG versus SIS did not have a significant relationship on likelihood of clinical pregnancy, after adjustment for treatment arm, BMI, duration of infertility, smoking, and education (OR 1.14, 95% CI 0.77, 1.67, P = 0.52). Ectopic pregnancy occurred more often in women who had tubal patency confirmed by HSG compared to SIS (2.8% versus 0.6%, P = 0.02). CONCLUSIONS: In this large cohort of women with PCOS, there was no significant difference in clinical pregnancy rate between women who had tubal patency confirmed by HSG versus SIS. SIS is an acceptable imaging modality for assessment of tubal patency in this population.

BACKGROUND: Human epididymis protein 4 is a serum biomarker to aid in differentiating benign and malignant disease in women with a pelvic mass. Interpretation of human epididymis protein 4 results relies on robust normative data. OBJECTIVE: The purpose of this study was to evaluate whether human epididymis protein 4 levels are variable in women during the normal menstrual cycle. STUDY DESIGN: Healthy women, 18-45 years old, with regular menstrual cycles were recruited from community gynecologic practices in Rhode Island. Women consented to enroll and to participate by the donation of blood and urine samples at 5 specific times over the course of each cycle. Levels of reproductive hormones and human epididymis protein 4 were determined. Data were analyzed with the use of linear regression after log transformation. RESULTS: Among 74 enrolled cycles, 53 women had confirmed ovulation during the menstrual cycle and completed all 5 sample collections. Levels of estradiol, progesterone, and luteinizing hormone displayed the expected menstrual cycle patterns. Levels of human epididymis protein 4 in serum were relatively stable across the menstrual cycle, except for a small ovulatory (median, 37.0 pM) increase. Levels of human epididymis protein 4 in urine, after correction for creatinine, displayed the same pattern of secretion observed in serum. CONCLUSION: Serum human epididymis protein 4 levels are relatively stable across the menstrual cycle of reproductive-aged women and can be determined on any day to evaluate risk of ovarian malignancy. A slight increase is expected at ovulation; but even with this higher human epididymis protein 4 level, results are well within the healthy reference range for women (<120 pM). Levels of human epididymis protein 4 in urine warrant further investigation for use in clinical practice as a simple and convenient sample.

Chronic pelvic pain can result from noncommunicating uterine cavities in patients with müllerian anomalies. Traditional management has been to resect the noncommunicating uterine horn. Two cases are described. One had a unicornuate uterus with noncommunicating left uterine horn (American Fertility Society [AFS] classification IIb) and the other had a normal external uterine contour with noncommunicating left uterine cavity that did not fit any category of the AFS classification of müllerian anomalies. Attempts at connecting the noncommunicating cavities hysteroscopically failed in both cases. Successful unification of the cavities was subsequently achieved in the first case using the classic Strassman metroplasty with the assistance of the robot. The unification of uterine cavities was achieved using a modified Strassman metroplasty in the second patient, as there was no uterine horn for landmark. Robot assistance was utilized in this case as well. Both patients are symptom free after surgery. We conclude that laparoscopic Strassman metroplasty, with or without robot assistance, is a viable alternative to resection of uterine horns in patients with hematometra, chronic pelvic pain, and noncommunicating uterine cavities.

The prevalence of obesity has doubled among reproductive-age adults in the US over the past 40 years and is projected to impact half of the population by 2030. Obesity is associated with a twofold to threefold increase in infertility, largely because of anovulation, and is associated with a lower rate of pregnancy with ovulation induction among anovulatory women. As a result of these trends and associations, in vitro fertilization (IVF) care will need to be adapted to provide safe, effective, and equitable access for patients with obesity. Research over the past 10 years has demonstrated safe sedation practices and effective procedure modifications for oocyte retrievals and embryo transfers in patients with obesity undergoing IVF treatment. We encourage IVF medical directors to revisit body mass index restrictions for IVF treatment in favor of individualized patient risk assessments to minimize weight bias and provide timely access to safe and effective IVF care for patients with obesity and infertility.

OBJECTIVE: To estimate patients' perceptions of the need, safety and acceptability of vaccination during pregnancy. STUDY DESIGN: An office-based survey was offered to patients presenting for obstetric and gynecologic care from December 2007 to July 2008 at an academic women's hospital. The anonymous questionnaire assessed demographics, medical and vaccination history, interest in receiving vaccines, and beliefs about vaccination safety. Data were evaluated using descriptive statistics and chi2 analyses. RESULTS: A total of 1,436 completed surveys were available for analysis, including 573 from pregnant women. Pregnant women were less likely than non-pregnant women to report perceived risks from vaccine-preventable illness (22.8% vs. 34.5%, p < 0.001) and to believe that their doctor thinks they should get vaccines (42.6% vs. 49.7%, p < 0.027). Nearly two-thirds (61%) reported concern about possible vaccine effects on their pregnancy. However, the overwhelming majority (89%) of pregnant women surveyed reported willingness to accept vaccination during pregnancy if recommended by their obstetrician. CONCLUSION: Despite concerns about vaccine safety and a low perceived need for immunization, most pregnant respondents endorse acceptance of vaccination when recommended by their obstetrician. These findings suggest that obstetric providers should maximize opportunities for uptake of appropriate immunizations during pregnancy.

Obesity has been associated with a multitude of medical comorbidities, infertility, and adverse obstetric outcomes. Weight stigma and weight bias pervade not only the medical field but also education, employment, and activities of daily living. The experience of weight stigma has been shown to adversely impact not only the mental health of individuals with overweight or obesity but also worsen obesogenic behaviors, and medical comorbidities. This review frames the rise of weight stigma and weight bias within the context of the "obesity epidemic" and explores its associations with infertility and decreased access to health care and its subsequent impact on the lives of individuals. Furthermore, it explores the concepts of intrinsic and extrinsic weight stigma/bias and highlights the need for further examination and research into the impact of these factors on access to reproductive medicine and subsequent outcomes.

Hyperandrogenism, insulin resistance, and acanthosis nigricans (HAIR-AN) is a severe subphenotype of polycystic ovary syndrome (PCOS). A 32-year-old woman with HAIR-AN and class 3 obesity presented to an endocrinology clinic after she failed sequential trials of treatment with metformin, estrogen-progestin OCP, spironolactone, leuprolide, and a levonorgestrel intrauterine device. She complained of hirsutism and acanthosis nigricans severely affecting her quality of life and had secondary amenorrhea. Laboratory evaluation showed extremely elevated testosterone and insulin levels and elevated glycated hemoglobin A1c (HbA1c). She underwent laparoscopic sleeve gastrectomy. One year after the surgery, she lost 32% of her body weight and reported normalization of menses, dramatic improvement in hirsutism, and near-resolution of acanthosis nigricans. Her testosterone, insulin, and HbA1c normalized. This case demonstrates the central role of hyperinsulinemia in HAIR-AN and suggests that aggressive measures to normalize insulin resistance and reduce excess weight can effectively treat the reproductive abnormalities in this syndrome. We suggest that bariatric surgery can be an effective cure for HAIR-AN syndrome and that PCOS, including HAIR-AN, should be considered a comorbidity of obesity during evaluation of bariatric surgery candidates.
RESUMO
Objective: To determine if moderate physical activity is associated with live birth rates in women with unexplained infertility and obesity. Design: Secondary analysis of the Improving Reproductive Fitness through Pretreatment with Lifestyle Modification in Obese Women with Unexplained Infertility trial. Setting: US fertility centers, 2015-2019. Patients: A total of 379 women participated in Improving Reproductive Fitness through Pretreatment with Lifestyle Modification in Obese Women with Unexplained Infertility trial, a lifestyle modification program with increased physical activity (phase I, 16 weeks) and up to three cycles of clomiphene citrate treatment and intrauterine insemination (phase II). Interventions: Participants were instructed to add 500 steps/day weekly until a maximum of 10,000 steps/day was reached and maintained. Participants were stratified as active (top third, N = 125) and less active (lower third, N = 125) on the basis of the average number of steps per day recorded using a FitBit activity tracker. Main Outcome Measures: Live birth rate. Results: Active participants were more physically active at the time of enrollment than less active participants (average baseline steps per day, 8,708 [7,079-10,000] vs. 4,695 [3,844-5,811]; P ≤ 0.001) and were more likely to reach 10,000 steps/day than less active participants (average steps per day, 10,526 [9,481-11,810] vs. 6,442 [4,644-7,747]; P ≤ 0.001), although both groups increased their average steps per day by a similar amount (1,818 vs.1,747; P = 0.57). There was no difference in live birth rates (24/125 [19.2%] vs. 25/125 [20%]; P = 0.87) between active and less active participants nor were there differences in clinical pregnancy rates (P = 0.45) or miscarriage rates (P = 0.49) between the two groups. Conclusions: Active participants were more likely to achieve the physical activity goal, although this was not associated with benefit or harm with respect to live birth. Clinical Trial Registration Number: ClinicalTrials.gov (NCT02432209), first posted: May 4, 2015.
RESUMO
Obesity, dieting, and weight cycling are common among reproductive-age women. Weight cycling refers to intentional weight loss followed by unintentional weight regain. Weight loss is accompanied by changes in gut peptides, adipose hormones, and energy expenditure that promote weight regain to a tightly regulated set point. While weight loss can improve body composition and surrogate markers of cardiometabolic health, it is hypothesized that the weight regain can result in an overshoot effect, resulting in excess weight gain, altered body composition, and negative effects on surrogate markers of cardiometabolic health. Numerous observational studies have examined the association of weight cycling and health outcomes. There appears to be modest association between weight cycling with type 2 diabetes mellitus and dyslipidemia in women, but no association with hypertension, cardiovascular events, and overall cancer risk. Interestingly, mild weight cycling may be associated with a decreased risk of overall and cardiovascular mortality. Little is known about the effects of weight cycling in the preconception period. Although obesity and weight gain are associated with pregnancy complications, preconception weight loss does not appear to mitigate the risk of most pregnancy complications related to obesity. Research on preconception weight cycling may provide insight into this paradox.

Adolescence is a period of flux for many body systems. While fertility potential typically increases after menarche, there are diseases where the opposite occurs and fertility preservation options need to be considered early. In cases of cancer, options vary by pubertal status and can include ovarian tissue cryopreservation, oocyte cryopreservation, sperm cryopreservation, and testicular tissue cryopreservation. Much remains to be learned about fertility and preservation options in those with differences in sexual development (DSDs); however, depending on the form of DSD, fertility preservation may not be necessary. Similarly, traditional fertility counseling in children with galactosemia may need to be changed, as data suggest that fertility rates attributed to other causes of premature ovarian insufficiency may not be as applicable to this disease. Adolescents with Turner's syndrome are at high risk for premature ovarian failure; therefore, it is important to consider options as early as possible since ovarian reserves are depleted quickly. On the other hand, transgender and gender diverse adolescents may even be able to undergo fertility preservation after starting hormone therapy. In all cases, there are additional ethical components including technical/surgical risks in childhood, offering experimental therapies without creating false hope and evaluating children's consent and assent capabilities that must be considered.

Objective: To report a case of a healthy, live birth resulting from a "chaotic" embryo (at least 6 chromosomal aneuploidies) after preimplantation genetic testing for aneuploidy (PGT-A). Design: Case report. Setting: University-affiliated fertility clinic. Patients: A same-sex couple with infertility due to failed donor intrauterine insemination and past implantation failure with in vitro fertilization (IVF)/intracytoplasmic sperm injection using donor sperm. Interventions: Frozen single embryo transfer of a "chaotic" embryo after genetic counseling and informed consent. Main Outcome Measures: Live birth of a healthy infant. Results: Controlled ovarian hyperstimulation and transvaginal oocyte retrieval in a 35-year-old female yielded 10 mature oocytes that underwent intracytoplasmic sperm injection with anonymous donor sperm and in vitro culture for 6 days. A single embryo underwent trophectoderm (TE) biopsy at the blastocyst stage and was cryopreserved. PGT-A revealed a "chaotic" test result. After genetic counseling and proper informed consent, a frozen single embryo transfer of this "chaotic" embryo resulted in a successful pregnancy and live birth of a healthy male infant. Conclusions: The reproductive potential of embryos with a "chaotic" TE biopsy result is unknown, but herein, we report a healthy, live birth from a "chaotic" embryo. We recommend that patients and providers faced with disposition decisions regarding "chaotic" embryos seek genetic counseling, consider rebiopsy, or consider transfer with informed consent.
RESUMO
PURPOSE OF REVIEW: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among reproductive-age women, the most common cause of infertility among women and a major contributor to pregnancy complications. RECENT FINDINGS: Diagnostic and associated features of PCOS, including hyperandrogenism, insulin resistance, and obesity, contribute to the 2-4-fold increased risk of pregnancy-induced hypertension and preeclampsia, gestational diabetes and preterm birth observed among pregnant women with PCOS. PCOS should be diagnosed according to the 2018 International Guideline. Screening for and optimizing management of hypertension, impaired glucose tolerance and obesity in the preconception window in women with PCOS provides an opportunity to increase the odds of a spontaneous pregnancy, live birth with fertility treatment and possibly reduce the risk of pregnancy complications. SUMMARY: Providers should prioritize individualizing recommendations for preconception health optimization in women with PCOS in order to maximize the chance of conception, a healthy pregnancy and the health of future generations.

Short and long-term weight reduction interventions are considered in the preconception period for women and men with obesity and infertility as obesity is associated with poorer reproductive outcomes. Short-term weight loss achieved with diet, exercise, and medications does not improve per cycle conception or live birth rates in women undergoing ovulation induction, intrauterine insemination, or in vitro fertilization (IVF), but may increase the rate of natural conception. Long-term weight loss achieved through surgical interventions may increase spontaneous conceptions, particularly among women with polycystic ovary syndrome, and may increase the live birth rate from IVF, though these findings are limited by recent evidence. There is a clear need for additional treatment options and well-designed weight loss intervention trials that address the heterogeneous causes of obesity among women and men with infertility and include fertility outcomes and perinatal morbidity as outcome measures.

RESEARCH QUESTION: Are preconception ovarian reserve markers, such as Anti-Mullerian hormone and antral follicle count, associated with preeclampsia and placenta mediated pregnancy complications among women with unexplained infertility who conceive with superovulation? DESIGN: This is a secondary analysis of women with unexplained infertility who had a singleton live birth after enrollment in the Analysis of Multiple Intrauterine Gestations after Ovarian Stimulation (AMIGOS) trial that randomized couples to superovulation with letrozole, clomiphene, or gonadotropins with insemination for up to 4 cycles. RESULTS: Compared to controls (N = 156), women who developed preeclampsia (N = 17) had lower Anti-Mullerian hormone levels (2.24 ± 1.20 vs. 2.89 ± 2.32, p = 0.07) and lower antral follicle count (18 ± 7.67 vs. 21 ± 11.43, p = 0.16); though these differences were not statistically significant. There was no relationship between Anti-Mullerian hormone (OR: 1.00, 95% CI: 0.76-1.25) or antral follicle count (OR: 0.98, 95% CI 0.93-1.04) with preeclampsia and between Anti-Mullerian hormone (OR: 1.00, 95% CI: 0.83-1.17) and antral follicle count (OR: 1.00, 95% CI: 0.97-1.04) with placenta medicated pregnancy complications after adjusting for age, BMI and race. CONCLUSIONS: Preconception ovarian reserve markers are not associated with preeclampsia and placenta mediated pregnancy complications among women with unexplained infertility who conceive with superovulation with insemination.
