title: Glucose and insulin levels after six months of treatment with a triphasic oral contraceptive containing ethinyl estradiol and norethindrone.
abstract: A prospective study of carbohydrate metabolism was done on 33 women who used a triphasic oral contraceptive (OC) containing ethinyl estradiol and norethindrone for six months. A three-hour oral glucose tolerance test was administered before and after the OC usage, and both the blood glucose and insulin levels were determined. A significant decrease in the fasting glucose level was found with treatment. All other glucose values and insulin levels were unchanged.
