    Vas Deferens

    Vas Deferens

    The vas deferens is a narrow, muscular tube that connects the testicles (where sperm is produced) to the urethra. During ejaculation, the sperm flows out of the testicles, through the vas deferens, and into the tube (urethra) that leads outside the body through the penis.

    Several glands, such as the prostate gland, add fluid to the sperm along the way.
