Effect of combined metformin and oral contraceptive therapy on metabolic factors and endothelial function in overweight and obese women with polycystic ovary syndrome.


PMID 21733508

Abstract

In this randomized, double-blind, placebo-controlled study, 19 overweight women with polycystic ovary syndrome were randomized to a 3-month course of either metformin plus combined hormonal oral contraceptive (OC) (n = 9) or OC plus matched placebo (n = 10). After 3 months, both treatments had similar effects on androgen levels, lipid profile, insulin sensitivity, and serum inflammatory markers, but flow-mediated dilatation increased by 69.0% in the metformin plus OC group while it remained unchanged in the OC group. CLINICAL TRIAL REGISTRATION NO: NCT00682890.
