Sexually mature male goats were used to study the hemodynamics of penile erection. Contrast medium was injected into the internal pudendal artery and serial angiographs of the erection, and detumescence phases of the erection cycle. The flow of contrast medium injected after erection by electrostimulation was blocked at the caudal edge of the ischial arch just proximal to the origin of the deep arteries of the penis. It is suggested that the major valvular mechanism that makes the corpus cavernosum penis a closed system during erection is a mechanical compression of the internal pudendal arteries, deep arteries of the penis external to or within the tunica albuginea of the crus, and veins against the ischium by contraction of the ischiocavernosus muscles. |
