Autophagy 2021 Jun 23:1-28. Epub 2021 Jun 23.

Pharmaceutics & Pharmacokinetics Division, CSIR-Central Drug Research Institute CSIR-Central Drug Research Institute, Lucknow, India.

Polycystic ovary syndrome (PCOS) is a unification of endocrine and metabolic disorders and has become immensely prevalent among women of fertile age. The prime organ affected in PCOS is the ovary and its distressed functioning elicits disturbed reproductive outcomes. In the ovary, macroautophagy/autophagy performs a pivotal role in directing the chain of events starting from oocytes origin until its fertilization. Read More

Natural Molecules in the Management of Polycystic Ovary Syndrome (PCOS): An Analytical Review.

Nutrients 2021 May 15;13(5). Epub 2021 May 15.

The Experts Group on Inositol in Basic and Clinical Research (EGOI), 00156 Rome, Italy.

Polycystic ovary syndrome (PCOS) is a heterogenous disorder characterized by chronic ovulation dysfunction and hyperandrogenism. It is considered the most common endocrinological disorder, affecting up to 25% of women of reproductive age, and associated with long-term metabolic abnormalities predisposing to cardiovascular risk, such as insulin resistance (IR), dyslipidemia, endothelial dysfunction, and systemic inflammation. PCOS is also characterized by elevated serum levels of luteinizing hormone (LH), causing a condition of hyperandrogenism and a consequent altered ratio between LH and the follicle stimulating hormone (FSH).
