Vas deferens
The vas deferens (also called the ductus deferens) is part of the human male anatomy. It is the main duct through which sperm travel during ejaculation. It connects the epididymis to the ejaculatory duct. It's name is Latin, literally meaning "carrying-away vessel". The plural form of vas deferens is vasa deferentia.
During ejaculation, the wall of the vas deferens thickens and thins itself, thus propelling the sperm.
