Testosterone is indispensable for the development of primary and secondary male sexual characteristics

Steroid hormone which represents the most common male sex hormone. Synthesized above all in the Leydig cells of the testis, it is produced, although in smaller quantities, also in the adrenal cortex. Even less significant quantities are also summarized by the ovaries and other organs that do not belong to the endocrine system in the strict sense, such as, for example, the skin and muscles. Of all the steroids — at 18, 19, 21 carbon atoms — isolated from the testicle, testosterone (19 carbon atom) is the one with the most androgenic activity, so much so that all the others are considered stages of its biosynthesis or products of its degradation. The liver is the organ that performs the maximum activity in the degradation of testosterone, which is excreted, with the 17-ketosteroid fraction, in the urine, mainly as sulfuric and glucuronic ester. Testosterone is indispensable for the development of primary and secondary male sexual characteristics, as well as for normal sexual function. Other effects of testosterone in the male organism concern: the stimulus to spermatogenesis and the growth of somatic tissues such as muscle tissue; the profound neurophysiological changes that characterize the behavioral mechanisms of the male sex (courtship, territorialism, etc.).

The hormone also performs multiple metabolic actions: its administration produces a clear anabolic effect at the level of protein synthesis, while its deficiency induces the appearance of creatinuria in the male and decreases in the musculature streaked with glycogen, phosphagen, and adenylpyrophosphoric acid.
