[Psychodynamics of the wish for a penis prosthesis].

The paper presents the results of the psychoanalytic investigation of 23 patients, who wanted a penile prosthesis because of psychogenic impotence. Unconscious motivations and the basal neurotic phantasies are demonstrated on the ego-psychological and drive oriented level. Usually surgeons and patients neglect the psychodynamic basis and complications of the symptom. The indication for the operation of patients suffering from psychogenic impotence has to be qualified.
