Diagnosis of Male Impotence

• Choi HK

Abstract

Historically as much as 90% of impotence has been labeled psychogenic in origin and only 10% is organic. Recent writers have indicated that as many as 30-50% of cases may be secondary to pertinent organic factors. The history physical examination have been the principal traditional means of establishing a diagnosis and the determing whether a psychological or organic disorder exists. Many other have been developed in an attempt to clarify and classify the etiologic factors. These tests include psychological screening, laboratory studies, nocturnal penile tumescence monitoring and in depth vascular and neurologic examinations. Progress in penile arterial revascularization makes it important for us to continue to reevaluate and refine our methodology for the diagnosis of vascular impotence with special emphasis on penile brachial index, penile flow index, pudendal angiogram, artificial erection test, papaverine test and computerized radionuclide erection penogram. Many of these methods are reviewed and the strengths and weekness of each in the overall evaluation are discussed.
