Vena dorsalis profunda penis

The deep dorsal vein of the penis lies beneath the deep fascia of the penis; it receives the blood from the glans penis and corpora cavernosa penis and courses backward in the middle line between the dorsal arteries; near the root of the penis it passes between the two parts of the suspensory ligament and then through an aperture between the arcuate pubic ligament and the transverse ligament of the pelvis, and divides into two branches, which enter the vesical and prostatic plexuses.

The deep vein also communicates below the pubic symphysis with the internal pudendal vein.
