Artery to the ductus deferens

The artery to the ductus deferens (deferential artery) is an artery in males that provides blood to the ductus deferens.

Origin
The artery arises from the superior vesical artery (usually), or from the inferior vesical artery.

Course, anastomoses, and distribution
It accompanies the ductus deferens into the testis, where it anastomoses with the testicular artery; in this way it also supplies blood to the testis and epididymis. A small branch also supplies the ureter.
