testosterone male sex hormone
Testosterone is a steroid hormone from the androgen group and is found in mammals, reptiles, birds, and other vertebrates. In mammals, testosterone is primarily secreted in the testes of males and the ovaries of females, although 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 the development of male reproductive tissues such as the testis and prostate as well as promoting secondary sexual characteristics such as increased muscle, bone mass and the growth of body-hair. In addition, testosterone is essential for health and well-being as well as the prevention of osteoporosis. On average, an adult human male body produces about ten times more testosterone than an adult human female body, but females are more sensitive to the hormone. (Wikipedia) For men only.
