Polycystic Ovarian Syndrome (PCOS) in Adolescence

Follicles of the ovary are the basic unit of female reproductive biology. They are usually round and contain a single egg or ovum. Normal ovarian volume in the menstruating females is 5-15 mL, with an approximate mean of 10 ml. Polycystic ovary syndrome (PCOS) is the leading cause of menstrual irregularities and hyperandrogenism in adolescents. In addition, it is the most common hormonal disorder in obesity and one of the most common causes of infertility in women. Although it was traditionally thought to be a problem of adulthood, it is now known that its onset takes place in childhood. It should be considered in any adolescent with hirsutism, persistent acne, dysfunctional uterine bleeding and/or obesity.
