Androgens


 * Testosterone (T) is the major androgen contributing to pubertal development in people with functional testes.
 * Dihydrotestosterone (DHT) is a metabolite of testosterone, and binds much more strongly to the androgen receptors. In adults it is known to cause balding and an enlarged prostate.
 * Dehydroepiandrosterone (DHEA) is a steroid hormone produced in the adrenal cortex from cholesterol. It is the primary precursor of natural estrogens. DHEA is also called dehydroisoandrosterone or dehydroandrosterone.
 * Androstenedione (A4) is an androgenic steroid produced by the testes, adrenal cortex, and ovaries. While androstenediones are converted metabolically to testosterone and other androgens, they are also the parent structure of estrone.
 * Androstenediol (A5) is a weak androgen produced as a metabolite of DHEA. Thought to act as the main regulator of gonadotropin secretion.
 * Androsterone is a chemical byproduct created during the breakdown of androgens, or derived from progesterone, that also exerts minor masculinising effects, but with one-seventh the intensity of testosterone. It is found in approximately equal amounts in the plasma and urine of both males and females.
