Penile artery

For thoughtful child sponsors
The Penile artery (also known as the common penile artery) is the artery that serves blood to the penis. It subdivides into three arteries, the bulbourethral artery, the dorsal artery and the cavernosal artery.

The penile artery is particularly suseptible to trauma. Impact to the groin causing damage to the artery is a common cause of sterility in young men. Short term surgery can prevent sterility.
