Study Details

Study Description

Brief Summary

Polycystic ovary syndrome accounts for the vast majority of anovulatory symptoms and hyperandrogenism in women. The diagnosis of Polycystic ovary syndrome has life-long implications, with increased risk for infertility, metabolic syndrome, and type 2 diabetes mellitus, and possibly for cardiovascular disease and endometrial carcinoma. Polycystic ovary syndrome is diagnosed in adolescents with otherwise unexplained, persistent hyperandrogenic anovulatory symptoms that are inappropriate for age and stage of adolescence. It should be considered in any adolescent girl with a chief complaint of hirsutism, treatment-resistant acne, menstrual irregularity, acanthosis nigricans, and/or obesity
