Quick Facts
Origin: Pampiniform plexus.
Course: Ascends in the abdominal cavity to drain into the inferior vena cava (on right side) and left renal vein (on left side).
Tributaries: Pampiniform plexus and ureteral veins.
Drainage: Drains testes, epididymis, ureter, and cremaster muscle.
Origin
The testicular veins arise from the terminal ends of the pampiniform plexuses, at around the level of the superficial inguinal ring.
Course
The testicular veins enter the abdomen and ascend. The right testicular vein empties directly into the inferior vena cava, while the left testicular vein drains into the left renal vein.
Tributaries
The testicular veins receive the pampiniform plexus and tributaries from the ureter.
Structures Drained
The testicular veins drain the testes, epididymis, ureter, and cremasteric muscle.
