Oxidative Stress and Polycystic Ovary Syndrome: A Brief Review

Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders, occurring in 5–10% women in reproductive ages. Despite a long history of studies on PCOS, its etiology is still unknown. Oxidative stress is now recognized to play a central role in the pathophysiology of many different disorders, including PCOS. Although intracellular reactive oxygen species (ROS) production and propagation are controlled by highly complex antioxidant enzymatic and non‑enzymatic systems, understanding of mechanisms that oxidative stress is important to develop strategies for prevention and therapy of PCOS. This article reviews the literature data related to the mechanisms of oxidative stress in PCOS.
