OBJECTIVE: The Anti- Muellerian Hormone (AMH) has been reported as surrogate marker of antral follicles, which are the origins of hyperandrogenism in polycystic ovarian syndrome (PCOS). Therefore, AMH may be useful for the diagnosis of PCOS. The objective was to study the longitudinal changes in AMH concentrations in girls with and without PCOS. DESIGN: This is a longitudinal study of obese girls participating in a 1-year lifestyle intervention. PATIENTS: Forty obese girls aged 13-16 years (50% with PCOS) were included in the study...

The presence of virilizing signs associated with high serum androgen levels in postmenopausal women is rare. Virilizing ovarian tumors (VOTs) and ovarian stromal hyperthecosis (OH) are the most common etiologies in virilized postmenopausal women. The differential diagnosis between these two conditions is often difficult. OBJECTIVE: To evaluate the contribution of clinical features, hormonal profiles and radiological studies to the differential diagnosis of VOT and OH. DESIGN: A retrospective study...

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder and the most common cause of female infertility. However, the etiology of the disease and the mechanisms by which this disorder progress remain unclear. Here we report that a transgenic obese mouse (Mito-Ob) developed by overexpressing prohibitin in adipocytes develops polycystic ovaries. Initially, the female Mito-Ob mice were equally fertile to their wild-type littermates. Mito-Ob mice begin to gain weight after puberty, become significantly obese between 3-6 months of age, and roughly 25% of them become infertile by 9 months of age...

We investigated the association between the apolipoprotein B (ApoB)/apolipoprotein A1 (ApoA1) ratio and insulin resistance (IR), metabolic syndrome (MS) and its components in Chinese polycystic ovary syndrome (PCOS) adults. We also examined whether hyperandrogenism is involved in obesity-related metabolic abnormalities in a cohort of patients. A clinical cross-sectional study consisting of 532 Chinese PCOS adults aged 20-38 years was designed. Each subject underwent a physical examination and laboratory evaluation...

Polycystic ovary syndrome (PCOS), affecting more than 5-10% of woman at reproductive childbearing age, is characterized by anovulation and hyperandrogenism. Frozen-thawed embryo transfer (ET) has been widely used for PCOS women to minimize the risk of ovarian hyperstimulation syndrome. However, the hyperandrogenic status of PCOS women deteriorates endometrial function, which has subsequently increased miscarriage rates in PCOS women. Therefore, we conducted this retrospective study to compare the pregnancy outcomes of hyperandrogenic PCOS women with (n = 29) and without (n = 31, controls) pretreatment of gonadotropin-releasing hormone (GnRH) agonist before frozen-thawed ET...

BACKGROUND/AIMS: Gonadotropin-releasing hormone analogues (GnRHa) represent the gold standard treatment for central precocious puberty (CPP). We aimed to assess the effects of GnRHa treatment on metabolic outcomes, bone status, and polycystic ovary syndrome (PCOS) prevalence in young girls with idiopathic CPP (ICPP). METHODS: We enrolled 94 ICPP girls who were at least 2 years after menarche and had already attained adult height at the time of the study: 56 previously treated with depot triptorelin (3...

Because animal and human studies indicate that androgen exposure can influence neurodevelopment, it has been hypothesized that prenatal exposure to excess androgens may predispose to disorders with male-skewed ratio such as autism spectrum disorders (ASD). Therefore, maternal conditions characterized by hyperandrogenism such as polycystic ovary syndrome (PCOS) or hirsutism may be relevant to child ASD. We previously found in a large Swedish case-control study of 23,748 ASD cases and 208,796 matched controls that PCOS in mothers is associated with increased offspring risk of ASD...

Hyperandrogenic women have various grades of ovulatory dysfunction, which lead to infertility. The purpose of this study was to determine whether chronic exposure to androgen affects expression of kisspeptin (ovulation and follicle development regulator) or release of luteinizing hormone (LH) in female rats. Weaned females were subcutaneously implanted with 90-day continuous-release pellets of 5α-dihydrotestosterone (DHT) and studied after 10 weeks of age. Number of Kiss1-expressing cells in both the anteroventral periventricular nucleus (AVPV) and arcuate nucleus (ARC) was significantly decreased in ovary-intact DHT rats...

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders that can lead to irregular menstrual cycles and hyperandrogenism. Reduced levels of progesterone and increased estrogen in these women can perpetually stimulate the endometrial tissue of the uterus. In this study, we assess the effect of PCOS induction by estradiol valerate (EV) in a rat model. MATERIALS AND METHODS: In this experimental study, adult female Wistar rats that weighed approximately 200 g were divided into control, sham, and experimental groups (n=6 per group)...

Polycystic ovary syndrome (PCOS) is generally considered a complex disorder caused by interactions between genetic and environmental factors. In a sub-cohort of women with PCOS visiting the preconception outpatient clinic of a tertiary hospital with follow-up in a periconception cohort, we identified specific dietary patterns and adherence in patients with PCOS with and without hyperandrogenism and the chance of ongoing pregnancy. Food frequency questionnaires were available from 55 patients diagnosed with PCOS during follow-up in routine clinical practice, including 25 with hyperandrogenism and 30 without hyperandrogenism...

BACKGROUND: Polycystic ovarian syndrome (PCOS) is a common cause of reproductive and metabolic dysfunction. We hypothesized that serum prostate-specific antigen (PSA) may constitute a new biomarker for hyperandrogenism in PCOS. METHODS: We conducted a cross-sectional study of 45 women with PCOS and 40 controls. Serum from these women was analyzed for androgenic steroids and for complexed PSA (cPSA) and free PSA (fPSA) with a novel fifth- generation assay with a sensitivity of ~10 fg/mL for cPSA and 140 fg/mL for fPSA...

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder of women of reproductive age characterized by polycystic ovarian morphology, anovulation or oligomenorrhea, and hyperandrogenism. It is shown that disruption in the steroidogenesis pathway caused by excess androgen in PCOS is a critical element of abnormal folliculogenesis and failure in dominant follicle selection. Vitamin D plays an important role in the regulation of ovulatory dysfunction and can influence genes involved in steroidogenesis in granulosa cells...

BACKGROUND: Hyperandrogenism and reduced skin autophagy have been implicated in the pathogenesis of adult female acne (AFA). Here, we tested whether a ready-to-use peel-off facial mask containing myoinositol (an androgen inhibitor) and trehalose-loaded liposomes (as activators of cutaneous autophagy) applied overnight every other day for 60 days can improve AFA. We also sought to investigate the molecular mechanisms underlying the clinical effects. OBJECTIVES: We conducted an uncontrolled, open-label clinical study in 40 cases of AFA to investigate the effect of the facial mask on lesion count, sebum production (measured with the Sebutape® technique), and Global Acne Grading System (GAGS) scale...

Adult rats treated concomitantly with insulin and human chorionic gonadotropin exhibit endocrine, metabolic, and reproductive abnormalities that are very similar to those observed in polycystic ovary syndrome (PCOS) patients. In this study, we used this rat model to assess the effects of metformin on PCOS-related uterine dysfunction. In addition to reducing androgen levels, improving insulin sensitivity, and correcting the reproductive cycle, metformin treatment induced morphological changes in the PCOS-like uterus...
