Gonadal Hormones & Inhibitors T2 Katzung & Trevor's Pharmacology: Examination & Board Review, 10e YR 2013 FD 2013 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-178923-3 LK accesspharmacy.mhmedical.com/content.aspx?aid=56983327 RD 2024/04/19 AB The gonadal hormones include the steroids of the ovary (estrogens and progestins) and testis (chiefly testosterone). Because of their importance as contraceptives, many synthetic estrogens and progestins have been produced. These 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 hyper-androgenism in women.
