Male hypogonadism is a common endocrine problem that affects men of all ages. Recently, there has been a surge in testosterone use among middle-aged and older men who in the past may have been considered to have borderline or even normal testosterone levels. This increasing use of testosterone therapy among men has paralleled the increasing improvements in the development of treatments for male hypogonadism that have been made over the past few decades. Current therapies using transdermal formulations and long-acting injectables such as testosterone undecanoate are quickly replacing the old injectable testosterone esters. In recent years, pharmaceutical sales and prescription data have readily shown a shift in the testosterone marketplace towards greater use of slightly more expensive treatments such as transdermal therapies, which are easier to administer and yield more physiological levels of testosterone. On the horizon are several new compounds in development, such as selective androgen receptor modulators (SARMS), 7α-methyl-19-nortestosterone, aromatase inhibitors, clomifene, dihydrotestosterone and human chorionic gonadotropin. Compounds such as SARMs are designed to selectively target androgen receptors in specific tissues (such as bone and muscles), in the hope of dispersing some of the side effects experienced on the prostate, which are presently associated with therapy of exogenous testosterone.
