The scrotal skin gets its blood from two areas: anterior scrotal arteries from the external pudendal (femoral origin) and posterior scrotal arteries from the internal pudendal via the perineal branch. The posterior scrotal arteries specifically supply the posterior aspect of the scrotum, making them the source for the posterior scrotal territory. The dorsal artery of the penis mainly vascularizes the penis itself, not the scrotal skin. The inferior rectal artery serves the anal region, and the artery of the bulb of the vestibule is a female structure, not involved in supplying the male scrotum. So the posterior scrotal branches best fit the vascular supply to the posterior scrotum.
