The tube through which the semen passed from the testicles to the ejaculatory duct is what?

The tube through which semen passes from the testicles to the ejaculatory duct is called the vas deferens. It transports sperm from the epididymis, where sperm is stored and matured, toward the ejaculatory duct, where it can mix with seminal fluid to form semen. The vas deferens is a muscular tube that plays a key role in the male reproductive system.
