Impotence, Vasculogenic

Impotence caused by a diminution of blood flow to the penis. Arteries involved can be the terminal aorta, hypogastric, pudendal, penile, and cavernous arteries. Ectopic drainage of the corpora cavernosa via large superficial dorsal veins or abnormally large cavernous and crural veins can cause venogenic impotence. (From Walsh, et al., Campbell's Urology, 6th ed, p720). The expression "venous leakage" is seen often in international literature. Leakage refers to the failure of the blood to reach the penile erectile tissues.
