Andropause: an old concept in new clothing.
There is increasing evidence that the common condition of hypogonadism in older men when associated with symptoms responds well to testosterone replacement. Over the last few years there has been a marked increase in the awareness and treatment of the andropause [137]. Long-term side effects of testosterone are uncertain with only eight people over 50 years having been studied for 10 years [138]. Testosterone needs to be considered a quality-of-life drug, similar to sildenafil, and at present it should be used only if it produces symptomatic improvement. There is a need for a men's health study to determine the long-term efficacy and safety of testosterone replacement in older persons.
