Arteria testicularis

Arteria Testicularis (also known as the Testicular Artery) is a branch of the abdominal aorta that supplies blood to the testis. It is a paired artery, with one for each testis.

Anatomy

The Arteria Testicularis originates from the anterior surface of the abdominal aorta, below the renal artery. It descends in the retroperitoneum, crossing the ureter and the iliacus muscle, before entering the inguinal canal through the deep inguinal ring. It then travels through the spermatic cord to reach the testis.

Function

The primary function of the Arteria Testicularis is to supply oxygenated blood to the testis and epididymis. It does this by branching into numerous smaller arteries within the testis, which then supply the individual seminiferous tubules.

Clinical Significance

The Arteria Testicularis can be involved in several medical conditions. For example, testicular torsion can lead to a twisting of the artery, cutting off blood supply to the testis and leading to testicular necrosis if not treated promptly. Additionally, varicocele, a condition characterized by dilated veins in the spermatic cord, can also involve the Arteria Testicularis.
