posterior scrotal artery

The posterior scrotal artery is a small arterial branch of the internal pudendal artery that supplies oxygenated blood to the scrotum, specifically its posterior aspect.

The posterior scrotal artery arises from the internal pudendal artery in the perineum and courses to the posterior surface of the scrotum. It runs within the superficial perineal pouch to reach its target tissue.

The posterior scrotal artery delivers oxygenated blood to the skin and subcutaneous tissues of the scrotum, supporting the viability of scrotal integument and underlying structures.

The posterior scrotal artery may be involved in perineal vascular injury following trauma, surgical procedures, or infection such as Fournier's gangrene. Compromise of its blood supply may be associated with poor wound healing in the perineal region.

The posterior scrotal artery is a small arterial vessel coursing in the superficial perineal tissues. It is typically visualized only on detailed angiographic studies or high-resolution pelvic imaging when specifically sought.
