Abstract

The present study was planned to evaluate the benefit of synergetic effect of Metformin plus Myo-inositol versus Metformin alone in infertile polycystic ovarian syndrome (PCOS) women undergoing ovulation induction. One hundred and twenty infertile PCOS women were randomized: Group I (n = 60) received Metformin (500 mg) plus Myoinositol(600 mg) three times a day; Group II received Metformin 500 mg three times a day. Subjects were advised to try for spontaneous conception. Those who did not conceive after 3 months, were given three cycles of ovulation induction + intrauterine insemination. Hormonal and biochemical profile parameters were done at baseline and after 3 months of therapy. Primary outcome measure was live birth rate. Secondary outcomes were improvement in menstrual cycle, hormonal and biochemical parameters, spontaneous conception, abortions, multiple pregnancy, and ovarian hyperstimulation syndrome. Baseline demographic, hormonal and biochemical parameters were comparable in two groups. There was a significant improvement in menstrual cycles (cycle length and bleeding days) in Group I as compared to Group II. The improvement in biochemical and hormonal parameters were comparable in the two groups after 3 months. Live birth rate was significantly higher in the Group I as compared to Group II [55% (33/60); 26.67% (16/60); p = .002]. The study concluded significantly higher live birth rate in women receiving the combination as compared to metformin alone.
