title: Erectile impotence: evaluation and management.
abstract: Dramatic progress in the understanding and treatment of erectile impotence has occurred over the past decade. Most cases have an organic cause that is related to vascular (arterial or venous) supply, innervation, or the hormonal milieu of the penis. Multifactorial causes of organic impotence are common and include diabetes mellitus, alcoholism, renal failure, and liver failure. Medications may cause impotence by a variety of mechanisms. The history and physical examination, along with simple laboratory tests, are the mainstay of evaluation and may be performed appropriately by family physicians. Successful new forms of nonsurgical treatment include penile self-injection with papaverine (sometimes with phentolamine) and penile-suction devices. Penile prostheses have been improved greatly in recent years. The patient may select among semirigid, multicomponent inflatable, and self-contained inflatable devices. New surgical treatments include penile arterial revascularization (for atherosclerosis) and ligation of the dorsal vein of the penis (for venous leak).
