PURPOSE OF REVIEW: Polycystic ovary syndrome (PCOS) is a common heterogeneous disorder that appears to have its origins during the peripubertal years. The diagnostic conundrum is that the typical clinical features, irregular menses and acne, occur during normal female puberty. Understanding the physiologic origins and molecular basis of the dysregulated hypothalamic-pituitary-gonadal axis in PCOS is fundamental to interrupting the distinctive vicious cycle of hyperandrogenism and chronic anovulation...

BACKGROUND: Dairy food intake has been associated with infertility; however, little is known with regard to associations with reproductive hormones or anovulation. OBJECTIVE: We investigated whether intakes of dairy foods and specific nutrients were associated with reproductive hormone concentrations across the cycle and the risk of sporadic anovulation among healthy women. METHODS: We prospectively measured serum reproductive hormones ≤8 times/menstrual cycle for 2 cycles from 259 regularly menstruating women (mean age: 27...

INTRODUCTION: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women. PCOS comprises a broad spectrum of anomalies, including hyperandrogenism, chronic anovulation, obesity, and infertility. Insulin resistance and its compensatory hyperinsulinemia play a key role in the pathogenicity of PCOS. This study compares the effects of 2 types of insulin sensitizer drugs, metformin and pioglitazone, on clinical, metabolic, and endocrine characteristics of women with PCOS...

BACKGROUND: Polycystic ovarian syndrome (PCOS), one of the leading causes of infertility seen in women, is characterized by anovulation and hyperandrogenism, resulting in ovarian dysfunction. In addition, associations of several metabolic complications like insulin resistance, obesity, dyslipidemia and psychological co-morbidities are well known in PCOS. One of the major factors influencing mood and the emotional state of mind is neurotransmitters. Also, these neurotransmitters are very crucial for GnRH release...

Polycystic ovary syndrome (PCOS) is a common cause of ovulatory dysfunction impacting women of reproductive age. Obesity and insulin resistance are thought to potentiate disruptions in antral follicle development that result in chronic anovulation, and as such, have become important therapeutic targets of dietary interventions aimed at weight loss. Caloric restriction has been shown to promote sporadic ovulation in obese women with PCOS, but improvements have occurred across a wide range of patients and little has been garnered about the factors that distinguish responders from non-responders...

AIM: Abnormal Uterine Bleeding (AUB) is a frequent reason for concern between adolescents. The most common cause of AUB in these girls, when other pathologies have been excluded, is Dysfunctional Uterine Bleeding (DUB). The aim of this review is to assess the role of DUB as an early symptom of Polycystic Ovarian Syndrome (PCOS) diagnosis later in life. METHODS: Review of the literature, using Pubmed and Medline as primary databases, regarding the correlation between DUB cases early after menarche and PCOS diagnosis in the future...

Infertility is common in the United States, with up to 15% of heterosexual couples experiencing difficulty in achieving conception. Family physicians often are the first physicians to evaluate couples attempting to conceive. Evaluation begins with assessment of ovulation, evaluation of anatomic abnormalities, and semen analysis. Many etiologies of anovulation can be managed by family physicians, and clinicians can offer counseling on timing of intercourse and assist patients with lifestyle changes to promote fertility...

Polycystic ovary syndrome (PCOS) is characterized by chronical anovulation and hyperandrogenism which may be present in a different degree of severity. Insulin-resistance and hyperinsulinemia are the main physiopathological basis of this syndrome and the failure of inositol-mediated signaling may concur to them. Myo (MI) and D-chiro-inositol (DCI), the most studied inositol isoforms, are classified as insulin sensitizers. In form of glycans, DCI-phosphoglycan and MI-phosphoglycan control key enzymes were involved in glucose and lipid metabolism...

Polycystic ovary syndrome (PCOS) is a syndrome associated with insulin resistance (IR), obesity, infertility, and increased cardiometabolic risk. This is a descriptive review of several mechanisms that can explain the IR among women with PCOS, other risk factors for the development of diabetes, and the screening methods used for the detection of glucose intolerance in women with PCOS. Few mechanisms can explain IR in women with PCOS such as obesity, insulin receptor signaling defects, and inhibition of insulin-mediated glucose uptake in adipocytes...
