Physiology of Erection and Management of Paraplegic Infertility

Abstract

The penis contains two erectile spaces, the cavernosal and the spongiosal, and erection depends on the filling of these spaces with blood. The cavernosal space consists of the right and left corpora cavernosa, which communicate freely with each other; the spongiosal space consists of the corpus spongiosum and the erectile tissue of the glans, which communicate freely with each other but not with the corpora cavernosa.
