A branch of the internal pudendal artery that supplies superficial structures of the perineum WordNet 3.0 & Open English WordNet

The perineal artery arises from the internal pudendal artery, and turns upward, crossing either over or under the superficial transverse perineal muscle, and runs forward, parallel to the pubic arch, in the interspace between the bulbospongiosus and ischiocavernosus muscles, both of which it supplies, and finally divides into several posterior scrotal branches which are distributed to the skin and dartos tunic of the scrotum.
