title: Impotence: a diagnostic approach.
abstract: A diagnostic approach to erectile impotence using a sexual function questionnaire, nocturnal penile plethysmography, penile blood pressure measurement, cavernosograms, cystometrograms and plasma testosterone levels is presented. Case examples demonstrate the clinical value of these diagnostic tools. Psychogenic impotence should be diagnosed only after nocturnal penile plethysmography has demonstrated the presence of complete erections.
