Abstract

Blood samples were taken for gases study (Po2, Pco2, pH, O2 saturation), simultaneously from corpus cavernosum, antecubital vein and femoral artery of 15 psychogenic impotent patients and 32 arteriogenic impotent patients 10 minutes after intracorporeal papaverine injection for artificial erection. The results were as follows: 1. In arteriogenic impotence, Po2, Pco2, O2 saturation of the corporeal blood were not significantly different from those of the femoral arterial blood but significantly different from those of the antecubital venous blood. 2. In psychogenic impotence, Po2, Pco2, O2 saturation of the corporeal blood were not significantly different from those of the femoral arterial blood but significantly different from those of the antecubital venous blood. 3. Po2, Pco2, O2 saturation of the femoral arterial, antecubital venous and corporeal blood in the arteriogenic impotence were not significantly different from those in the psychogenic impotence. Therefore, PO2, Pco2, O2 saturation of the corporeal blood during erection state are the picture of the arterial blood and not significantly different between the arteriogenic and psychogenic impotence.
