Because of their extensive use as contraceptives and replacement therapy, many synthetic estrogens and progestins have been produced. Related agents include synthesis inhibitors, receptor antagonists, and some drugs with mixed effects (ie, agonist effects in some tissues and antagonist effects in other tissues). Mixed agonists with estrogenic effects are called selective estrogen receptor modulators (SERMs). Synthetic androgens, including those with anabolic activity, are also available for clinical use. A diverse group of drugs with antiandrogenic effects is used in the treatment of prostate cancer and benign prostatic hyperplasia in men and androgen excess in women. Some gonadal hormones are also produced in the adrenal cortex.
