Characteristics of erectile dysfunction as a function of medical care system entry point.

The scientific literature on the treatment of penile erectile dysfunction contains numerous contradictory reports on the relative frequency of organic causes of impotence and the treatment results of behavioral sex therapy. One explanation for these contradictory findings is the hypothesis that different investigators are studying different subsamples of the symptomatic population. This study investigated differences in characteristics of men who initially consulted a urologist with a complaint of impotence versus those who self-referred themselves to a sexual dysfunction clinic. Self-referred sexual dysfunction patients were more often white, more often had psychogenic etiologies to their difficulties, were more often of higher socioeconomic class, and had a much better response to psychological interventions. This study suggests that future studies concerning the etiology and treatment of impotence need to specify population characteristics such as referral source and screening criteria. It may be necessary to develop alternative treatment techniques for men who present to nonpsychiatric sources for help with psychogenic impotence.
