title: Diagnostic evaluation of erectile dysfunction.
abstract: Erectile dysfunction, the persistent inability to attain or maintain penile erection sufficient for sexual intercourse, affects millions of men to various degrees. The majority of cases have an organic etiology, most commonly vascular disease that decreases blood flow into the penis. Regardless of the primary cause, erectile dysfunction can have a negative impact on self-esteem, quality of life and interpersonal relationships. The initial step in evaluation is a detailed medical and social history, including a review of medication use. Discussion with the patient's sexual partner may clarify exacerbating issues. The physical examination focuses on the cardiovascular, neurologic and urogenital systems. Laboratory tests are useful to screen for common etiologic factors and, when indicated, to identify hypogonadal syndromes. Appropriate evaluation of erectile dysfunction leads to accurate advice, management and referral of patients with erectile dysfunction.
