Testosterone Definition
What Is Testosterone?

Male sex hormone (androgen) secreted by the interstitial cells of the testis of mammals and responsible for triggering the development of sperm and of many secondary sexual characteristics. These are the hormones responsible for increased size and hard, lean muscle. Testosterone is the most potent of the male steroid sex hormones, which are collectively known as androgens. It is produced by the interstitial (Leydig) cells of the testis, and acts locally to stimulate development of sperm. Rapid weight loss may also lead to lower testosterone levels. To offset this decline and in the hope of retaining youthful virility, some people intake testosterone preparations. Testosterone enhance libido, energy, immune function, and protection against osteoporosis. These hormones are administered to some anorexics to help them build muscle mass and aid their recovery. Low levels may also reduce a person's energy capacity by affecting the body's ability to store energy in the form of creatine phosphate and glycogen.
