A spermatic cord is connected to each testicle to help keep the
testicle in position and supply the penis with semen. The cord contains veins,
arteries, nerves, lymph vessels, and part of the tube that carries sperm called
the vas deferens.
The spermatic cord extends upward from the epididymis, a small
sac-shaped structure that lies behind each testicle.
