What is "desogestrel"

n. A molecule used in hormonal contraceptives.

Desogestrel ( INN, USAN, BAN) is a progestin used in hormonal contraceptives. Most combined oral contraceptive pills (COCPs, or simply OCs) on the market today contain both an estrogen ( ethinyl estradiol is common) plus a progestin (a synthetic progesterone-like agent) such as desogestrel. Desogestrel-containing birth control pills are sometimes referred to as "third generation" oral contraceptives. In contrast, birth control pills that are considered "second generation" ( Tri-Levlen, for example) contain an estrogen and a progestin, but the progestin is different, such as levonorgestrel.

Desogestrel behaves as a prodrug to etonogestrel (3-ketodesogestrel). It has low androgenic activity.
