title: Impotence in diabetics: organic versus psychogenic factors.
abstract: Four types of impotence were diagnosed in 75 consecutive impotent diabetic patients: chronic persistent organic type due to vascular and/or neurologic factors (44%), temporary organic types due to medical illness other than diabetes (10.6%) or uncontrolled metabolic state (6.6%), and psychogenic impotence (38.6%). Despite higher incidence of organic etiology (61.3%) the incidence of psychogenic impotence was significant. None of the methods used to diagnose the type of impotence in the present study proved 100 per cent accurate, and we advise a combination of history-taking including the wife's history, physical examination including vascular and neurologic tests, nocturnal penile tumescence studies, and therapeutic trials with sex therapy to differentiate between true organic, temporary organic, and psychogenic types of impotence in diabetic patients. This differentiation is mandatory since the latter two types may have a better prognosis.
