Testosterone

Testosterone is a steroid hormone from the androgen group. In mammals, testosterone is primarily secreted in the testes of males and the ovaries of females. Small amounts are also secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid. In men, testosterone plays a key role in health and well being as well as in osteoporosis. On average, an adult human male body produces about forty to sixty times more testosterone than an adult female body, but females are from a behavioral perspective more sensitive to the hormone.
