Comparison of Single and Combined Treatment with Exenatide and Metformin on Menstrual Cyclicity in Overweight Women with Polycystic Ovary Syndrome

COM appears better than either EX or MET alone on menstrual cycle frequency and hormonal and metabolic derangements. A marked decrease in central adiposity could partly explain the improvements in reproductive function, insulin-glucose parameters, and adiponectin observed in these overweight women with PCOS treated with COM therapy. Larger trials of longer duration are warranted to assess the long-term efficacy and safety of combined EX-MET therapy in overweight women with PCOS.
