Abstract
A multicenter trial was carried out by 13 independent German investigators to evaluate a new oral contraceptive combination containing 0.150 mg desogestrel+0.020 mg ethinylestradiol, paying particular attention to cycle control and efficacy. This German trial, being part of a larger European open multicenter study in 12 countries, comprised 235 women and a total of 5758 cycles. Despite the very low estrogen dose, this combination showed a good cycle control. The frequencies of absence of withdrawal bleeding and the occurrence of irregular bleeding, which were already low during the initial treatment cycles, gradually decreased over the subsequent cycles. In most women the amount and duration of withdrawal bleeding were similar to or slightly less than those of the menstrual bleeding before treatment. The combination showed a good contraceptive efficacy. 3 pregnancies (all 3 patient failures) occurred (in the larger European study comprising 1684 women and 25970 cycles, no other patient failures than these 3 German cases occurred; in addition there was one tablet failure). The preparation was well tolerated. There were no serious side effects and the frequency of minor subjective complaints was very low.Keywords
