Androgens and male sexual behavior from mice to men.
Exogenous androgenic hormones or drugs that affect endogenous androgen levels are now used in a variety of human applications [cf. Bardin et al. (1991)]. Therefore, an increasing number of well-controlled physiological, clinical, and psychological studies have examined the effects of androgens on muscle, prostate, lipids, and bone, as well as the cardiovascular, immune, and nervous systems. The increasing number of androgens and delivery systems that are currently available or under development should also increase the prevalence of androgen therapy (Table 1). As androgen use increases, a crucial area of research is the effect of androgens on sexual behavior, which encompasses sexual desire, motivation, performance, and satisfaction. There is a large body of animal data documenting hormonal regulation of male sexual behavior and the neural sites of action of these hormones. Clinical data on the effects of androgens on human male sexuality come from correlative studies of endogenous testosterone levels and sexual function, treatment of men who are testosterone deficient, and men using hormonal contraceptives.
