title: Carbohydrate studies in women using a norethindrone triphasic oral contraceptive for eighteen months.
abstract: Twenty women were tested before and after eighteen months of use of triphasic oral contraceptive (TOC) containing norethindrone and ethinyl estradiol (7-7-7). The evaluation was with an oral glucose tolerance test and plasma glucose and insulin levels were measured. The results showed a lower fasting glucose and elevated one-hour insulin values after TOC use. These results suggest improved safety with these contraceptives.
