Desogestrel and ethinyl estradiol combination is used to prevent pregnancy. It is a birth control pill that contains two types of hormones, desogestrel and ethinyl estradiol, and when taken properly, prevents pregnancy. It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization (pregnancy) is prevented.
