The androgenic polycystic ovary
American Journal of Obstetrics and Gynecology, 1976The polycystic ovary has the capacity to produce excessive androgens (delta4-androstenedione, dehydroepiandrosterone, and testosterone). Whether this disorder is caused by constant pituitary priming of the ovaries due to hypothalamic-pituitary derangement or an ovarian enzyme defect, the end result is the same, i.e., abnormal androgen production. In an

Polycystic ovary syndrome (PCOS) is a complex and still poorly understood process. This review examines current theories regarding the development of PCOS and focuses on the physiologic processes involved in the pubertal and adolescent period and their relationship with pathogenesis of PCOS.

Polycystic ovary syndrome, characterized by hyperandrogenism and menstrual irregularities, is a heterogeneous group of disorders that can disrupt normal hypothalamic-pituitary-ovarian function. Ovarian physiology is reviewed with regard to possible etiologies for excessive androgen secretion. Similar features may be present in errors in steroidogenesis,

Polycystic ovaries and obesity
Best Practice & Research Clinical Obstetrics & Gynaecology, 2015Almost 50% of the women with polycystic ovary syndrome (PCOS) are obese. Obesity in PCOS affects reproduction via various mechanisms. Hyperandrogenism, increased luteinizing hormone (LH) and insulin resistance play a pivotal role. Several substances produced by the adipose tissue including leptin, adiponectin, resistin and visfatin may play a role in ...

Women with polycystic ovarian syndrome have chronic anovulation and androgen excess not attributable to another cause. This condition occurs in approximately 4% of women. The fundamental pathophysiologic defect is unknown, but important characteristics include insulin resistance, hyperandrogenism, and altered gonadotropin dynamics.

POLYCYSTIC OVARY SYNDROME [PDF]
Endocrinology and Metabolism Clinics of North America, 1998 Polycystic ovary syndrome is a syndrome and not a disease. It reflects multiple potential etiologies and variable clinical presentations that are reviewed in this article. In addition to menstrual dysfunction and hyperandrogenism, women with polycystic ovary syndrome also may have hypothalamic-pituitary abnormalities, polycystic ovaries on pelvic ...

Function of the polycystic ovary
Human Fertility, 2000The mechanism of the increase in the number of follicles in polycystic ovaries (PCO) is still not understood, but most data indicate that folliculogenesis is abnormal at all stages. This increase is probably due to prolonged follicle growth in both ovulatory (ov) and anovulatory PCO (anovPCO) rather than over-recruitment from the primordial stage ...

Polycystic ovary syndrome (PCOS), a heterogeneous and chronic condition, today affects about 5% of women of reproductive age. PCOS is strongly associated with states of insulin resistance and hyperinsulinemia. Risk factors include genetics, metabolic profiles, and the in utero environment.

A New Approach to Polycystic Ovary Syndrome: The Gut Microbiota
Journal of the American College of Nutrition, 2019Polycystic ovary syndrome (PCOS) is a widespread endocrine disease that affects 6% to 20% of women of reproductive age and is associated with high risk of infertility, obesity, and insulin resistance.
