testosterone

testosterone
n.
the principal male sex hormone (see androgen). Formed from androstenedione within the interstitial cells of the testis, it is converted in target cells to dihydrotestosterone, which mediates most of its actions. Preparations of testosterone are used for replacement therapy in males with testosterone deficiency; they can be administered orally, by intramuscular depot injection, or topically (in the form of skin patches or gels).
