Purpose: Treatment of Asherman syndrome (AS) presents a significant clinical challenge. Based on our in vitro data showing that PRP could activate endometrial cell proliferation and migration, we hypothesized that intrauterine infusion of autologous platelet-rich plasma (PRP) may improve endometrial regeneration and fertility outcomes in patients with moderate-severe AS.

Materials And Methods: Subjects with moderate-severe AS were randomized to PRP or saline control administered following hysteroscopic adhesiolysis.

Background: Physical activity is a cornerstone for treatment of women with polycystic ovary syndrome (PCOS), but there are limited data on their exercise behaviors. A previous study identified PCOS patients of non-White ethnicity to be at higher risk for inadequate physical activity. Further data is needed to identify groups that would benefit from additional counseling in achieving adequate physical activity (APA).

Objective: To report on the semen quality parameters in transgender women who pursued semen cryopreservation either in the presence or absence of gender-affirming hormonal medication.

Materials And Methods: This retrospective cohort study was conducted as a chart review of consecutive transgender women presenting for semen cryopreservation between January 1, 2012 and March 31, 2018. Demographic data and semen parameters were assessed.

Objective: To compare age-associated changes in cardiovascular risk markers in lean and obese reproductive-aged women with polycystic ovary syndrome (PCOS) with community controls.

Design: Longitudinal study at an academic medical centre PATIENTS: Patients diagnosed with PCOS by 2004 Rotterdam criteria in a multidisciplinary clinic were systematically enrolled from 2006-2014 in a PCOS cohort study and subsequently agreed to participate in a longitudinal study. The comparison controls were from the prospective, longitudinal Ovarian Aging (OVA) study, which consists of healthy women with regular menstrual cycles recruited from 2006 to 2011.

Objective: Due to its consistent elevation in polycystic ovary syndrome (PCOS) and correlation with polycystic ovarian morphology (PCOM), anti-Mullerian hormone (AMH) has been proposed as a marker of the syndrome. However, prior studies reporting thresholds of AMH for a PCOS diagnosis have been limited by small sample size, inappropriate controls, and heterogeneous AMH assays. We sought to evaluate the suitability of a standardized AMH assay as a biomarker of PCOS.

Background: Polycystic ovary syndrome (PCOS) is a very common disorder well known to be associated with insulin resistance and metabolic disease. Insulin resistance is likely involved in the promotion of the PCOS reproductive phenotype and may mediate some of the ovarian morphology seen in the disorder. The phenotype of each individual woman with PCOS can vary widely as can her metabolic risk.

Objective: To characterize the population of patients excluded from a diagnosis of polycystic ovary syndrome (PCOS) when follicle number criteria are increased to 25 per ovary as suggested by the Androgen Excess and Polycystic Ovary Syndrome Society's recent task force.

Design: Cross-sectional study.

Setting: Tertiary academic center.

The impact of long-term tamoxifen therapy on ovarian function is not known. Understanding these effects will help reproductive-aged patients who desire future pregnancy make more informed decisions regarding their treatment. This is a retrospective cohort study in patients identified through the UCSF Cancer Registry and SPORE database.

Preimplantation culture of mouse embryos has been suggested to result in reduced anxiety-like behavior in adulthood. Here, we investigated the effects of in vitro fertilization (IVF), embryo culture, and different diets on anxiety-like behavior using the elevated plus maze (EPM). We hypothesized that exposure to suboptimal conditions during the preimplantation stage would interact with the suboptimal diet to alter behavior.

Menstrual irregularity has been associated with insulin resistance, type 2 diabetes mellitus and markers of metabolic dysfunction. This study aimed to determine whether irregular menstrual cycles (MCs) in reproductive-age women are associated with the weight of their daughters at birth and growth up to age five. We studied 4863 pregnant women with menstrual history data in a prospective cohort, recruited from the Kaiser Health Plan (1959-1966).
