Incidence of elevated LH/FSH ratio in polycystic ovary syndrome women with normo- and hyperinsulinemia.

Abstract

LH/FSH ratio is not a characteristic attribute of all PCOS women: in the present study this abnormality was detected in a subpopulation smaller than 50%. Most of the PCOS women with normal gonadotropin ratio belong to a group of patients suffering from hyperinsulinemia and obesity. Patients with hyperinsulinemia and excess of LH constitute a selected and distinct subgroup with increased adrenal androgenic activity.
