All consecutive patients presenting with erectile dysfunction and undergoing penile color Doppler evaluation with injection PGE1 20 mcg were included in this study.A total of 70 patients with an age range of 24-70 years (mean 41 +/- 12.25 years) were included in the study. A normal response was noted in 45 (psychogenic) cases. Vasculogenic causes were observed in 23 patients, 12 with arterial insufficiency and 11 with venous leak.
