taxon notes

In humans, the right testicular vein generally joins the inferior vena cava; the left testicular vein, unlike the right, often joins the left renal vein instead of the inferior vena cava. The 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 constitutes the greater mass of the spermatic cord; the vessels composing this plexus are very numerous, and ascend along the cord, in front of the ductus deferens. Below the subcutaneous inguinal ring, they unite to form three or four veins, which pass along the inguinal canal, and, entering the abdomen through the abdominal inguinal ring, coalesce to form two veins, which ascend on the Psoas major, behind the peritoneum, lying one on either side of the internal spermatic artery. 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
