Superficial dorsal veins of penis

In human male anatomy, the dorsal veins of the penis are blood vessels that drain the shaft (corpora cavernosa, corpus spongiosum), the skin and the glans of the human penis. They are typically located in the midline on the dorsal aspect of the penis and they comprise the superficial dorsal vein of the penis, that lies in the subcutaneous tissue of the shaft, and the deep dorsal vein of the penis, that lies beneath the deep fascia.
