Description

A male sex hormone that causes male sex characteristics to develop (such as deep voice and facial hair) and stimulates the development of the male reproductive system and sexual activity.

Testosterone is made mainly by the testicles. Small amounts of testosterone are also made in the adrenal glands. It may also be produced in the lab to treat certain conditions.
