    The vas deferens is also known as a sperm duct or ductus deferens. The ejaculatory duct is a lengthy muscular tube that goes from the epididymis into the pelvic cavity behind the bladder and links to the urethra.
    • Sperm cells are produced in the testes. The sperm then travels to the epididymis, a structure that sits at the top of the testicle. The epididymis is responsible for storing sperm cells and maturing them so they can fertilize eggs.  Muscle contractions transfer sperm from the epididymis to the vas deferens and then into the urethra when a person is sexually stimulated, allowing  the discharge of sperm outside of the body. To make semen, the body adds fluids to the sperm cells during the procedure.
      • The scrotum, or sac holding your testicles, is where the vas deferens originates. The vas deferens next passes into your body from the testicle. It extends until it connects with the seminal vesicle’s duct to form the ejaculatory duct. The vas deferens, or ductus deferens, can range in length from 30 to 45 centimeters (nearly 12 to 18 inches). Some sections are coiled, while others are straight. The tube is classified as fibromuscular, which means it is made up of fibrous and muscle tissue.
