Danazol is a derivative of the synthetic steroid ethisterone, a modified testosterone. Although effective for endometriosis, its use is limited by its masculinizing side-effects. Its role as a treatment for endometriosis has been largely replaced by the GnRH agonists. The agent is fat-soluble. It is an isoxazole of testosterone with isolated weak androgenic activity and no estrogenic or progestagenic effects. Danazol is contraindicated in pregnancy because it could masculinize a female fetus.
