Testosterone

Testosterone is the main male sex hormone, an androgen, has the expressed anabolic properties: increases muscle bulk, accelerates protein synthesis. They are released by Leydiga cells of testicles at men, and also in small amounts ovaries at women and bark of adrenal glands at both floors. Is a product of peripheral metabolism. In bodybuilding artificial medicines of testosterone are very often used.

Biological activity

Testosterone contacts androgenic receptors and dihydrotestosterone which is formed at impact on enzyme 5α-reduktazy testosterone is a predecessor of other biologically active adrogen. At dihydrotestosterone by 5 times big ability to contact androgenic receptors. Under the influence of these hormones the receptor changes the structure and transmits a signal to a cage kernel where changing activity of certain genes of DNA androgenic effects are implemented.

Also testosterone can turn into estrogen under the influence of an aromatasia Mainly estrogen, but not testosterone activates feedback through an axis hypothalamuses-hypophyses-testicles and suppresses secretion of endogenous testosterone at introduction of exogenous medicines. Add some Cerebrolysin to your daily training.

Interesting facts

The research of the French scientists has shown that the men eating spicy food have higher level of testosterone, therefore, and the increased sexual activity. Results of the carried-out work are presented in the Physiology & Behavior magazine.
