Testosterone is a word that is derived from testis (testicle) and steroid. It was created by Ernst Laqueur, who first isolated it from bull testicles. Through the discovery of Ernst laqueurs, the distinction has been set between maskolin and feminine. In women, the ovaries and the adrenal cortex produce low amounts of testosterone.

In men, testosterone for the most part under the influence of LH (luteinizing hormone) in the Leydigschen between cells in the testicles is produced. Testosterone has a direct effect on the testicles. It carried bound to a protein blood too many other target organs, have receptors for this hormone. The transport protein called sex hormone binding globulin. Credit: DriWay-2011. In the body is a part of testosterone through the 5a-reductase enzyme to biologically more active dihydrotestosterone metabolized. A negative feedback, testosterone in the pituitary inhibits the secretion of luteinizing hormone and in the hypothalamus that of GnRH, which is called also gonadotropin releasing hormone. Not only the science interested in testosterone, it is widely used in the scene of bodybuilders and athletes very known as doping substances.

Androgens are anabolic effect, which means that they promote the bone and muscle growth. The goal is as fast as possible to get by one injected testosterone before training to muscle mass. The property of this method includes visible results after just a few days, making it a medium that speeds up the muscle, as well as the mass building. There are many different forms of taking testosterone. Some bodybuilders and endurance athletes or famous actor testosterone as doping substances, use their muscle to accelerate or to overcome the natural limits.
