Organic impotence

Organic impotence consider if the inability of the patient to erections, and their preservation is not associated with psychogenic disorders. Impotence of vascular origin

From organic disorders vascular pathology most likely cause of impotence. Padrino-cavernous arterial system supplying the penis with blood, includes internal iliac (podshivnoy) artery, internal pudendal artery and artery of the penis and the cavernous bodies. This system has the unique ability to dramatically increase blood flow in response to stimulation (sexual) pelvic splanchnic (excitatory) nerves.

Normal blood flow is 10 ml/min at rest and approximately 60 ml/min during stimulation. It is this rapid increase in blood flow along with neurogenic redistribution of blood flow in the cavernous body cause an erection. Insufficient pressure of blood in the small blood vessels of the arterial bed during sexual stimulation leads to an inadequate supply of blood to the corpus cavernosum and incomplete erection. This, apparently, is the explanation of the close relationship of impotence with aging, and discovered Kinsey.


The degree of lesion of the arterial bed may be different, so different may be the increasing blood flow during sexual stimulation that leads to pressure variations in the cavernous bodies. For example, the complete absence of erections may indicate a serious vascular pathology, and relatively good erection alone disappear when coital frictions the can be a manifestation of a less severe vascular disease. In the second case, impotence may be due to the syndrome “victimize” the pelvic vessels. If the blood flow in the iliac artery is limited, and in the internal pudendal artery occlusion there, there is a redistribution of blood flow in the vessels of striated muscles with less resistance. Such vessels are in the gluteal muscles, supplied with large upper and lower gluteal arteries, which are branches of the iliac and internal pudendal artery.
