PCOS in adolescents

Polycystic ovary syndrome (PCOS), a heterogeneous syndrome of unknown aetiology, is the leading cause of anovulation, hirsutism and infertility in women. This multifactorial syndrome emerges at puberty and has cardiovascular and metabolic sequelae through menopause. The common features of normal puberty, namely menstrual irregularities and insulin resistance, obscure the diagnosis of adolescent PCOS, while there are no established diagnostic criteria for PCOS in this age group. The clinical implications of PCOS diagnosis in adolescents remain unclear. Experts in the field still ponder whether PCOS should be managed at such a young age with a view to hindering the long-term sequelae of the syndrome.
