How Does Vas Deferens Work

Vas deferens: The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra, the tube that carries urine or sperm to outside of the body, in preparation for ejaculation.

How does the vas deferens move sperm?

Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra. When ejaculation occurs, rhythmic muscle movements propel the sperm forward.

Does vas deferens absorb sperm?

This layer absorbs excess liquid and dead sperm while secreting nutrients to support sperm during their storage and transportation. The middle layer of the ductus deferens is by far the thickest layer and contains many elastin fibers and visceral muscle cells arranged in longitudinal and circular bundles.
