Abstract
Erectile dysfunction is defined as the inability to obtain and/or sustain an erection adequate for vaginal penetration and satisfactory completion of sexual intercourse. Differential diagnosis of the two main causes of erectile dysfunction — organic and psychogenic impotence — is often impossible during a routine examination. Psychological exploration fails to discriminate between organic and psychogenic impotence [18]. Men with suspected psychogenic erectile dysfunction have neither more nor fewer pathological deviations on the Minnesota Multiphasic Personality Inventory (MMPI), California Psychological Inventory (CPI), or Derogatis Sexual Functioning Inventory (DSFI) than do those with objective organic disorders [20, 25].
