These unite to form a single vein, which opens, on the right side, into the inferior vena cava at an acute angle , on the left side into the left renal vein at a right angle . The spermatic veins are provided with valves . The left spermatic vein passes behind the iliac colon and is thus exposed to pressure from the contents of that part of the bowel. Pathology Since the left testicular vein goes all the way up to the left renal vein before it empties, this results in a higher tendency for the left testicle to develop varicocele because of the gravity working on the column of blood in this vein. Moreover, the left renal vein passes between the abdominal aorta and the superior mesenteric artery en route to the inferior vena cava, and is often compressed by an enlarged superior mesenteric artery.
