title: Danazol and fetal masculinization: a warning.
abstract: Masculinization of a female fetus occurred during a pregnancy in which the mother received danazol for infertility due to endometriosis. The biochemical theories and the necessary treatment are outlined. Conception may occur before or during a course of danazol, and patients should be made aware of the need for concomitant contraception.
