Picture credit: Wikipedia Any of a group of male sex hormones that stimulate development of the testes and male secondary sexual characteristics, such as growth of facial hair. The primary and best-known androgen is testosterone. Androgens are produced principally by the testes when stimulated by luteinizing hormone but they are also secreted in smaller amounts by the adrenal glands and (in women ) the ovaries. Androgen is the generic term for any natural or synthetic compound, usually a steroid hormone, that stimulates or controls the development and maintenance of masculine characteristics in vertebrates by binding to androgen receptors. Androgens, which were first discovered in 1936, are also called androgenic hormones or testoids. They are the original anabolic steroids. They are also the precursor of all estrogens, the female sex hormones.
