Growth Hormone and Insulin-like Growth Factors

A longitudinal prospective study was conducted in 21 women with polycistic ovary syndrome (PCOS), aged 27.20 +/- 5.02 years and treated with metformin (1500 mg/day)for 8 weeks. The patients were assessed for spontaneous menstruation, weight, body mass index (BMI), waist circumference, waist/hip ratio (WHR), glucose and insulin concentrations under fasting conditions and after a 75-g glucose tolerance test, lipid profile, testosterone, androstenedione, dehydroepiandrosterone sulfate, sex-hormone binding globulin (SHBG), and insulin-like growth factor (IGF)-I. Spontaneous menstruation was observed in 81% of the women treated with metformin, with no changes in weight or BMI. Waist measurement and the WHR were reduced. The quantitative insulin sensitivity check index (QUICKI) improved from 0.33 +/- 0.03 to 0.35 +/- 0.04 (p < 0.005), and serum total cholesterol and low-density lipoprotein-cholesterol were reduced, while high-density lipoprotein-cholesterol was increased. Serum testosterone concentrations were also reduced. There were no differences in serum triglycerides, SHBG or IGF-I. The occurrence of spontaneous menstruation and changes in the pattern of body fat distribution, the reduction in serum testosterone concentrations, the improvement in lipid profile and the reduction of insulinemia with the use of metformin permit us to conclude that treatment with this drug is of benefit to women with PCOS.
