[Effects of metformin on insulin resistance and on ovarian steroidogenesis in women with polycystic ovary syndrome].

Background: Polycystic ovary syndrome is considered the most frequent endocrine abnormality during the fertile age. Hyperinsuli-nemia, typical of this syndrome, alters the functionality of the cytochrome P450 c 17 alfa and this causes an exaggerated secretion of male hormones produced by the female gonad. Objective of this study was to verify if the reduction of the circulating insulin levels, obtained through therapy with metformin, caused the reduction of LH levels, LH:FSH ratio, of testosterone and androstenedione levels, but also of cholesterolemia, triglyceridemia, BMI, and naturally of insulinemia, glycemia, as well as an increase in HDLC (high density lipoprotein cholesterol).
