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

[citation needed] The artery arises from the superior vesical artery (usually),[1] or from the inferior vesical artery.

[2] 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.
