Abstract
We evaluated 67 patients 18 to 60 years old (mean age 28.5 years) with primary erectile dysfunction (absence of full sustained erections since early childhood or puberty) using a multidisciplinary approach. Organic causes of the erectile dysfunction were found in 57 of the 67 patients (85 per cent): 12 (18 percent) had neurological, 35 (52 per cent), arteriogenic and 35 (52 per cent venogenic abnormalities. Psychogenic facturs were diagnosed in 11 patients (16 per cent), while in 4 (6 per cent) a classification was not possible. Concomitant psychogenic abnormalities were found in 39 of the 57 patients (68 per cent) with organic primary erectile dysfunction. Our results suggest that primary erectile dysfunction is caused mainly by organic factors. However, for successful therapy the frequent secondary psychogenic abnormalities must be considered.
