Infertility care of the PCOS patient

When approaching the management of infertility in the polycystic ovarian syndrome (PCOS) patient, there are several important considerations for maximizing favorable reproductive outcomes. Prior to conception, healthy lifestyle habits should be prioritized, with a focus on healthy body mass, optimal blood glucoses, and balanced diet and exercise regimens. Pharmacologic fertility strategies include aromatase inhibitors and selective estrogen receptor modulators (SERMs) as first-line agents. Gonadotropins can be considered when these agents fail. Alternatively, laparoscopic ovarian drilling can be utilized as a second-line approach when surgical management is indicated or desired. In vitro fertilization (IVF) is generally considered third-line unless there is an absolute indication for its use. A variant of traditional IVF known as in vitro maturation (IVM) may prove useful in this patient population to reduce the risk of …

Antimüllerian hormone level predicts ovulation in women with polycystic ovary syndrome treated with clomiphene and metformin

ObjectiveTo describe the serum anti-Müllerian hormone (AMH) concentrations in a large, well-phenotyped cohort of women with polycystic ovary syndrome (PCOS) and evaluate whether AMH predicts successful ovulation induction in women treated with clomiphene and metformin.DesignSecondary analysis of randomized controlled trial.SettingNot applicable.Patient(s)A total of 333 women with anovulatory infertility attributed to PCOS who participated in the double-blind randomized trial entitled the Pregnancy in Polycystic Ovary Syndrome I (PPCOS I) study (registration number, NCT00068861) who had serum samples from baseline laboratory testing available for further serum analysis were studied.Intervention(s)Not applicable.Main Outcome Measure(s)The association between the baseline AMH levels in each of the 3 treatment groups and ovulation, pregnancy, and live birth rates were assessed.Result(s)A …

Best Methods in Reproductive Medicine Clinical Trials

This introduction is to a Views and Reviews series of article outlining best practices in the design and analysis of reproductive medicine articles. The authors are experienced researchers and biostatisticians who highlight keypoints with illustrative examples from both published and theoretical clinical studies. This series is meant not only to educate readers in the interpretation of clinical research studies but inspire better designed studies in the future.

Ovarian Morphology in Non-Hirsute, Normo-Androgenic, Eumenorrheic Premenopausal Women from a Multi-Ethnic Unselected Siberian Population

Polycystic ovary syndrome (PCOS) is a highly prevalent disorder in women, and its diagnosis rests on three principal features: ovulatory/menstrual dysfunction, clinical and/or biochemical hyperandrogenism, and polycystic ovarian morphology (PCOM). Currently, data on age- and ethnicity-dependent features of PCOM remain insufficient. We aimed to estimate ethnicity- and age-dependent differences in ovarian volume (OV) and follicle number per ovary (FNPO) in a healthy, medically unbiased population of Caucasian and Asian premenopausal women, who participated in the cross-sectional Eastern Siberia PCOS epidemiology and phenotype (ESPEP) study (ClinicalTrials.gov ID: NCT05194384) in 2016–2019. The study population consisted of 408 non-hirsute, normo-androgenic, eumenorrheic premenopausal women aged 18–44 years. All participants underwent a uniform evaluation including a review of their medical history and a physical examination, blood sampling, and pelvic ultrasonography. The statistical analysis included non-parametric tests and the estimation of the upper normal limits (UNLs) by 98th percentiles for OV and FNPO. In the total study population, the upper OV percentiles did not differ by ethnicity or age group. By contrast, the UNL of FNPO was higher in Caucasian women than in Asian women, and women aged <35 years demonstrated a higher UNL of FNPO compared to older women. In summary, these data suggest that the estimation of FNPO, but not OV, should take into account the ethnicity and age of the individual in estimating the presence of PCOM.

Total and bioavailable 25-hydroxyvitamin D is not associated with improved sexual dysfunction following vitamin D supplementation in women with polycystic ovarian syndrome: a …

Background Vitamin D (Vit D) deficiency has been linked to symptoms of polycystic ovary syndrome (PCOS), yet little is known about Vit D supplementation as a treatment for sexual dysfunction (SDy) in women with PCOS. Aim To explore the implications of serum total 25-hydroxyvitamin D (25[OH]D) and bioavailable 25[OH]D (bio-25[OH]D) status and replacement on women with PCOS and SDy. Methods Reproductive-age women with PCOS who were not desiring fertility were eligible provided that they also had SDy, as assessed by the Female Sexual Function Index (FSFI), and were without severe depression, as evaluated by the Beck Depression Inventory II (BDI-II). Participants were given the recommended dietary allowance of Vit D (600 IU daily) plus hormonal contraception (HC; cyclic ethinyl estradiol/drospirenone) or no HC for 6 months …

Polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) affects 5–20% of women of reproductive age worldwide. The condition is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology (PCOM)—with excessive androgen production by the ovaries being a key feature of PCOS. Metabolic dysfunction characterized by insulin resistance and compensatory hyperinsulinaemia is evident in the vast majority of affected individuals. PCOS increases the risk for type 2 diabetes mellitus, gestational diabetes and other pregnancy-related complications, venous thromboembolism, cerebrovascular and cardiovascular events and endometrial cancer. PCOS is a diagnosis of exclusion, based primarily on the presence of hyperandrogenism, ovulatory dysfunction and PCOM. Treatment should be tailored to the complaints and needs of the patient and involves targeting metabolic abnormalities through lifestyle …

Genomic and proteomic evidence for hormonal and metabolic foundations of polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) and its underlying features remain poorly understood. In this genetic and proteomic study, we expand the number of genetic loci from 19 to 29, and identify 31 associated plasma proteins. Many risk-increasing loci were associated with later age at menopause, underscoring the reproductive longevity related to a larger functional ovarian reserve. Hormonal regulation in the aetiology of this condition, through metabolic and reproductive features, was emphasised. The proteomic analysis highlighted perturbations of metabolically-related biology that are typical in women with PCOS. A PCOS polygenic risk score was associated with adverse cardio-metabolic outcomes, with differing contributions of testosterone and BMI in women and men. Finally, while oligo- and anovulatory infertility are characteristic features of PCOS, we observed no impact of PCOS susceptibility on childlessness. We suggest that PCOS susceptibility confers balanced pleiotropic influences on fertility in women, and life-long adverse metabolic consequences in both sexes.
