Background:
Progesterone is a steroid secreted by the corpus luteum and placenta. It is responsible for preparing the uterine lining for implantation of a fertilized ovum and to maintain pregnancy. Norgestrel is a synthetic progestin and a racemic mixture of dextronorgestrel and levonorgestrel , of which levonorgestrel is the biologically active component. In vivo, norgestrel administered via intrauterine device (IUD) prevents pregnancy in rats. Formulations containing nogestrel have been used as contraceptives.
