Desogen products are effective oral contraceptives (birth control pills or "the pill"). These products combine natural or synthetic estrogens and progestins, similar to the natural sex hormones (estrogen and progesterone) produced in a woman's body. Ethinyl estradiol is an estrogen and desogestrel is a progestin. These products can prevent ovulation and pregnancy. In general, a combination of estrogen and progestin works better than a single-ingredient product. Ethinyl estradiol/desogestrel tablets can also help to regulate menstrual flow, treat acne or may be used for the other hormone related problems among females. The type and amount of estrogen and/or progestin may be different from one product to another.
