Diabetes mellitus vascular lesion

Vascular pathology may involve lesions of the inflow or outflow mechanisms of penile erection. Erectile dysfunction may be a manifestation of generalized atherosclerosis and may even be its initial presentation. Common risk factors associated with generalized penile arterial insufficiency include hypertension, hyperlipidemia, cigarette smoking, diabetes mellitus, and pelvic irradiation (Rosen et al. 1991). Less commonly, local stenosis of the conunon penile artery may occur in men who have sustained blunt pelvic or perineal trauma (Levine et al. 1990).
