    Abstract:
    Ovarian hyperandrogenism can be associated with insulin resistance, hyperinsulinemia, glucose intolerance, and obesity. High levels of the lipostatic hormone, leptin, have also been reported in this condition. The purpose of the present study was to examine the effect of an oral contraceptive (OC) of low androgenicity containing desogestrel on glucose tolerance in hyperandrogenic women and the impact of changes in androgenic/estrogenic status on leptin concentrations. Sixteen nondiabetic hyperandrogenic women, aged 29 +/- 1 yr with a body mass index (BMI) of 36.8 +/- 1.8 kg/m2, underwent an oral glucose tolerance test before and after 6 months of therapy with the OC. Free testosterone decreased and sex hormone-binding globulin increased after therapy (P < 0.001). Glucose tolerance deteriorated significantly, and two women developed diabetes. Body weight, BMI, and leptin did not change significantly. Leptin correlated with BMI before (r = 0.56; P = 0.02) and after (r = 0.51; P = 0.04) treatment, but not with glucose, insulin, total and free testosterone, or sex hormone-binding globulin before or after treatment. In conclusion, 1) glucose tolerance should be monitored in hyperandrogenic women using OC, even those of low androgenicity; and 2) changes in androgenic/estrogenic status had no effect on the leptin concentration, suggesting that its sexual dimorphism is not related to sex steroids. Ovarian hyperandrogenism can be associated with insulin resistance, hyperinsulinemia, and glucose intolerance--all of which, in turn, have been linked to high levels of the lipostatic hormone, leptin. This study investigated the effect of an oral contraceptive (OC) containing a progestin of low androgenicity on glucose tolerance and insulinemia in hyperandrogenic women and the impact of changes in androgenic/estrogenic status on plasma leptin levels. 16 nondiabetic hyperandrogenic US women (mean age, 29 years) with a mean body mass index of 36.8 kg/sq. m underwent oral glucose tolerance testing before and after 6 months of treatment with an OC containing 30 mcg of ethinyl estradiol and 150 mcg of desogestrel. Treatment was associated with significant decreases in free testosterone and increased sex hormone-binding globulin (p 0.001). Glucose tolerance deteriorated moderately but significantly. After 6 months of treatment, 5 women had normal glucose tolerance, 9 had impaired glucose tolerance, and 2 developed non-insulin-dependent diabetes mellitus. There were no significant changes in serum insulin concentrations, body weight, body mass index, or leptin, but leptin levels were highly correlated with body mass index both before and after treatment. The data suggest that the sexual dimorphism of leptin is not caused by differences in sex hormones. Even when OCs containing low androgenic progestins are prescribed, women at high risk for diabetes should receive regular glucose tolerance tests.
