[Polycystic ovary syndrome in obese or type 1 diabetic (T1D) adolescent girls].

Polycystic ovary syndrome (PCOS) is frequent during adolescence (prevalence ≈ 6 %), and the prevalence increases in obese or type 1 diabetic (T1D) adolescent girls. During puberty, PCOS diagnosis is difficult because of the overlap with some pubertal physiologic signs. The 2017 international consortium suggests two required diagnostic criteria: persistent menstrual disturbances and hyperandrogenism.
