spermatic vein

An obsolete term that formerly dignified either the left or right testicular vein.

spermatic vein

In males, the veins that accompany the testicular artery and that drain the testis and epididymis. In the spermatic cord, the spermatic veins form the pampiniform plexus. After emerging from the deep inguinal ring, the spermatic veins merge into two veins, which continue to accompany the testicular artery. Eventually, the two spermatic veins merge into a single vein on each side, and the right spermatic vein empties into the inferior cava (below the renal vein), while the left spermatic vein empties into the left renal vein.
