Treatment of impotence. 1. Nonsurgical methods.

Male sexual dysfunction is a problem that is quite prevalent in our society. Until recently, the only treatments for impotence were testosterone injection, sex therapy, and implantation of a penile prosthesis. These methods remain in use when appropriate. However, now that the pathophysiology of erection is better understood, the dopamine agonist, intracorporal injection, and the alpha 2-adrenergic receptor blocker have been added to the treatment list. Gadgets that artificially increase the blood supply to the penis are sometimes used. The withdrawal of drugs that affect sexual function may be sufficient.
