Psychogenic erectile dysfunction is defined as the persistent inability to achieve or maintain erection satisfactory for sexual performance owing predominantly or exclusively to psychologic or interpersonal factors. This definition recently was adopted by the International Society of Impotence Research<sup>22LoPiccolo J. Postmodern sex therapy for erectile failure. Erectile Disorders: Assessment and Treatment New York: Guilford Press (1992).  171-197

Epidemiologic studies have highlighted the prevalence of psychosocial factors in the etiology of erectile dysfunction. In the Massachusetts Male Aging Study,<sup>11Feldman H.A., Goldstein I., Hatzichristou D.G., y al.

Depressed mood was found to be a significant predictor of erectile dysfunction, even after controlling for potential confounding factors.<sup>3Araujo A.B., Durante R., Feldman H.A., y al.

Socioeconomic factors, including a decrease in household income during the past 5 years, also were significantly associated with the incidence of erectile dysfunction. Overall, these studies underscore the independent and interactive effects of psychosocial factors in the etiology of erectile dysfunction.
