Testicular vein

Testicular Vein

The testicular vein and its relationship with the kidney and inferior vena cava. (Testicular vein labeled at center right.)

The testicular vein (or spermatic vein) is a paired vein that drains the testis. It is part of the male reproductive system and plays a crucial role in the transportation of deoxygenated blood from the testis back to the heart.

Anatomy

The testicular veins emerge from the back of the testis, and receive tributaries from the epididymis. They unite and form a convoluted plexus, called the pampiniform plexus, which is part of the spermatic cord. This plexus ascends along the cord and through the inguinal canal into the abdominal cavity.

Clinical significance

Abnormalities in the testicular vein can lead to conditions such as varicocele, which is characterized by the enlargement of the veins within the scrotum. This condition is similar to varicose veins that can occur in the leg.
