One hundred impotent men.

One hundred men complaining of poor or absent erectile capacity were investigated with a multidisciplinary approach. Their median age was 47 years. Mainly organic causes of the erectile failure were found in 27 and mainly psychologic in 40 cases, while factors of both types contributed in 33 cases. Vascular disorder was present in 20 men, including (functional) vasoconstriction in eight. Among 24 men with serum testosterone below 15 nmol/l the incidence of arterial disease, alcoholism and partner-related problems was significantly higher than in those with higher testosterone levels. Most psychologic factors were in general intrapsychic (affecting only the patient himself), while a minority were dyadic (related to the partner).
