Posterior scrotal arteries

Posterior Scrotal Arteries

The Posterior Scrotal Arteries are a pair of arteries that supply blood to the scrotum in males. They are branches of the internal pudendal artery, which is a branch of the internal iliac artery.

Anatomy

The posterior scrotal arteries arise from the internal pudendal artery in the perineum. They pass medially towards the scrotum, supplying the skin and muscles of the posterior part of the scrotum.

Function

The primary function of the posterior scrotal arteries is to supply oxygenated blood to the skin and muscles of the posterior part of the scrotum. This is crucial for the maintenance of normal scrotal function and health.

Clinical Significance

Understanding the anatomy of the posterior scrotal arteries is important in surgical procedures involving the scrotum and perineum. Damage to these arteries during surgery can lead to complications such as scrotal hematoma and impaired scrotal function.
