Vas deferens
The vas deferens (plural: vasa deferentia), also called ductus deferens, (Latin: "carrying-away vessel"; plural: ductus deferentes), is part of the male anatomy of many vertebrates ; they transport sperm from the epididymis in anticipation of ejaculation.
The epididymis connects the testes with the ductus deferens. Sperm mature and are stored in the epididymis before moving into the ductus deferens for ejaculation.
The ductus deferens is part of the vas deferens and connects the epididymis and ejaculatory ducts.
The vas deferens (ductus deferens) begins at the epididymis and ends at the ejaculatory duct.
The tube is called the spermatic cord, which contains the vas deferens and blood vessels that supply the testes.
An average of 2mm. A certain study concluded: ranging from 1.7 to 2.8 mm.
