Testosterone is a steroid hormone that is present in the bodies of both men and women, although men have higher concentrations of it. Testosterone is made in the testes, ovaries, and adrenal glands and is derived from cholesterol. It is primarily responsible for the development of the male reproductive system and also plays a role in body hair growth, muscle mass, fat distribution, voice depth, and libido. In the body, some testosterone is converted into dihydrotestosterone, which plays a role in prostate enlargement and baldness, and estradiol, which is a type of estrogen.
