Evaluation the Effect of Metformin on Hormones Serum Levels in Women With Polycystic Ovary Syndrome

Abstract

Background: Polycystic ovary syndrome [PCOS] is a common disease that affected the reproductive problem. Aim: the study tried to determine the association between PCOS with the body mass index (BMI) and the effect of metformin as treatment for PCOS.
 Patients and Methods: This case control prospective experimental study was carried out in Kirkuk General Hospital from January 2014 to July 2014. The recruited cases divided into three groups; Group I, 68 women with normal menstrual cycle as control group; Group II, 61 cases diagnosed as a PCOS; and Group III :- 30 cases selected from group two to receive treatment with Metformin to determine the effect of the treatment on different variables. Results: The highest percentage of PCOS (36.1%) was found in those with age group between (20-25) years. Most (65.6%) of PCOS subjects were with overweight or obese. BMI mean value was (28.92±6.68) in women with PCOS, while in control the corresponding value was (25.09±4.35). FSH, and testosterone were significantly higher in women with PCOS than in control. Metformin reduced serum FSH, LH, prolactin and testosterone, with non-significant difference. Conclusion: PCOS is independently associated with elevated BMI. Metformin treatment of PCOS induced t reduction in serum testosterone and FSH, LH and serum prolactin but not reach significant level. This warranted performance a large scale clinical trial to evaluate the therapeutic effect of metformin alone or in combination with diet control approach for treatment of PCOS. These findings have implications for the pathophysiology of obesity development and management in PCOS.
