Sign in to saveAlso known as ductus deferens
part of the male reproductive system of many vertebrates
The vas deferens is a tube in the male reproductive system that carries sperm from where it's produced to where it's released during ejaculation. It's an important part of how males reproduce because it's the main pathway that allows sperm to reach the urethra and exit the body.

Encyclopedic overview
3D medical illustration showing vas deferens. The vas deferens (pl.: vasa deferentia), ductus deferens (pl.: ductūs deferentes), or sperm duct is part of the male reproductive system of many vertebrates. In mammals, spermatozoa are produced in the seminiferous tubules and flow into the epididymal duct. The end of the epididymis is connected to the vas deferens. The vas deferens ends with an opening into the ejaculatory duct at a point where the duct of the seminal vesicle also joins the ejaculatory duct. The vas deferens is a partially coiled tube which exits the abdominal cavity through the inguinal canal.
