Polycystic ovary syndrome and estroprogestins

Introduction: Clinical characteristics of polycystic ovary syndrome (PCOS) (menstrual irregularities, obesity, anovulation, etc.), occur together with a series of conditions at skin level like seborrhea, acne, hirsutism, and androgenetic alopecia. Estroprogestins (EPs) are recognized as the most powerful therapy to treat hyperandrogenism and/or hyperandrogenemia and regularize menstrual cycle. Evidence acquisition: This review includes the most relevant publications about the effects of EPs in PCOS women published between 1995 and 2025. Evidence synthesis: According to the available data, EPs composed by an anti-androgenic progestin appear the most suitable to reduce the hyperandrogenic manifestations of PCOS. More specifically, cyproterone acetate (CPA), drospirenone (DRSP) and dienogest (DNG) associated with 20-30 μg of ethinylestradiol (EE) seem to be the most effective compounds for the management of androgen excess. As the benefit risk/ratio of the association EE/CPA is less favorable, the use of EPs with other antiandrogenic progestins could be more appropriate to treat PCOS patients, also from a metabolic point of view. Conclusions: In conclusion, an aware choice of the most adequate and tolerable EP formulation according to the pharmacological profile and individual characteristics of PCOS patient is essential to opportunely customize the treatment of androgen excess.
