[Hormonal changes in the elderly from the viewpoint of the andrologist]

Although the aging male experiences a decrease in genital function, it is not as pronounced or as complete as in the female ovary, so that this process is only remotely similar to the climacteric. The most important sign is a decrease in erection frequency and other sexual functions. This is, however, not due simply to a decrease in testosterone levels. For numerous studies have clearly shown that the number of sexual performances is independent of current testosterone levels. A qualitative change in Leydig cell function can, however, be concluded from the "latent androgen deficit", reduced stimulability of the Leydig cells, and the frequent anomalies of the levels of such other hormones as FSH and LH in patients with impotence. Thus, the treatment of "impotence" with oral or depot testosterone is indicated in proven manifest or latent androgen deficiency.
