Objective: To study the accurate relationship between the erectile dysfunction and atherosclerosis risk factors (ARF). Methods: The distribution of four main atherosclerosis risk factors (ARF)(including diabetes,smoking,hyperlipidaemia (HLP), and hypertension) were studied in 382 ED patients (mean age 46.6). The penile arterial & venous system hemodynamics was measured by penile duplex ultrasonography and/or 99mTc and ll3mIn dual radioisotope technique. 97 volunteers or male infertile patients (mean age 44.8) with normal erectile function were selected as controls. Results: All ED patients and 97 controls were grouping in 4 sub-groups by the number of ARFs. In 178 (82.4%) of 216 there was evidence of arterial lesion. Smoking (69%), diabetes (26%), and HLP (41%) were all significantly more common in the whole 382 ED patients than in the controls. Whenever two or more ARFs were present mean RI, PSV, EDV, PIA and PIV were abnormal. The frequency of organic ED increased from 31% in absence of any ARF to 100
