Definition, Diagnosis, and Epidemiology of the Polycystic Ovary Syndrome
The Polycystic Ovary Syndrome (PCOS) is a heterogeneous disorder, whose principal features include androgen excess, ovulatory dysfunction, and/or polycystic ovaries, and is recognized as one of the most common endocrine/metabolic disorders of women. This syndrome was first described by Stein and Leventhal in 1935 , although the presence of sclerocystic ovaries had been recognized for at least 90 years before the publication of that seminal work. Following, we review the definition, diagnostic scheme, and epidemiology of PCOS as it currently stands.
