dttore, dottore .... che cos'è il testosterone ?

è quella cosa che tu maschietto hai in abbondanza e che ti fa cadere i capelli e crescere il pelo ! che palle direte, ma cercando tra le pagine web ... ho trovato questo:

Testosterone is a steroid hormone from the androgen group. Testosterone is secreted in the testes of men and the ovaries of women. It is the principal male sex hormone and the "original" anabolic steroid. In both males and females, it plays key roles in health and well-being. Examples include enhanced libido, energy, immune function, and protection against osteoporosis.
Like other steroid hormones, testosterone is derived from cholesterol. The largest amounts of testosterone are produced by the testes in men, but it is also synthesized in smaller quantities in women by the theca cells of the ovaries, by the placenta, as well as by the zona reticulosa of the adrenal cortex in both sexes.
In the testes, testosterone is produced by the Leydig cells. The male gonads also contain Sertoli cells which require testosterone for spermatogenesis. Like most hormones, testosterone is supplied to target tissues in the blood where much of it is transported bound to a specific plasma protein, sex hormone binding globulin (SHBG).
ora finalmente èun po' + chiaro cos'è il testosterone ?
si si... grazie dottore :-p
