This research was carried out to evaluate the prevalence of carotid and/or lower limb artery abnormalities in patients with arterial erectile dysfunction (ED). To this end, patients with ED (Andrology Unit) or suspected peripheral atherosclerosis (Angiology Unit) underwent an independent and parallel echo-Duplex examination. The Andrology Unit examined 167 patients with ED of different etiologies: 52 of them had penile artery insufficiency and consequently their carotids and lower limb arteries had to be evaluated by means of echo-Doppler. In all, 36 out of the 46 patients with nonarterial organic ED and 22 out of the 69 patients with nonorganic ED underwent the same evaluation and served as controls. The Angiology Unit enrolled 457 ED patients who initially underwent echo-Doppler for suspected carotid and/or arterial leg atherosclerosis and subsequently dynamic echo-Doppler. Isolated penile artery insufficiency was found in 23.1 and 25% of the patients evaluated in the Angiology and Andrology Units, respectively. The remaining patients were shown to have ED associated with an atheroma or marked intima-media thickness of the carotid vessels and/or of leg arteries. The frequency of penile arterial insufficiency and of carotid and/or lower limb artery abnormalities was significantly higher (P < 0.01) compared to that found in patients with ED of nonarterial organic or psychogenic origin. Both Units found that the frequency of penile artery insufficiency and carotid or lower limb artery abnormalities was significantly higher than that of penile artery insufficiency alone or plus both carotid and lower limb artery abnormalities. This study showed that penile artery insufficiency is associated with carotid and/or lower limb artery ultrasound abnormalities in about 75% of the cases. Therefore, arterial ED may be regarded as a sign of a more generalized atherosclerosis.
