Is Reducing Ovarian Volume in Polycystic Ovarian Syndrome Patients after Administration of Metformin Associated with Improving Cardiovascular Risk Factors?

Background: Women with polycystic ovary syndrome (PCOS) are at increased risk for cardiovascular (CV) and metabolic disorders. There is a close relationship between elevated androgen plasma levels and the ultrasound findings of stromal hypertrophy. In randomized trials, the administration of metformin has been shown to be followed by an improvement in insulin sensitivity and decrease in androgen levels in most women. In the present study, we investigate the association between reduced ovarian volume in PCOS patients after administration of metformin with improvement in CV risk factors. Materials and Methods: This was a randomized clinical trial study. A total of 28 women diagnosed with PCOS who referred to the infertility clinic were selected. Anthropometric characteristics of the patients, mean ovarian volume and plasma levels of fasting blood sugar (FBS), lipid profile, luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol, testosterone, 17-α-OH progesterone (17OHP), dehydroepiandrosterone sulfate (DHEAS), C-reactive protein (CRP) and homocysteine (Hcy) were evaluated before and after treatment with 500 mg metformin, three times daily for three months. Statistics were calculated wit
