Vas deferens
The vas deferens (or ductus deferens) [1] is a duct in a man’s body. It is also present in other male vertebrates. Its function is to carry sperm away from the testes.

Vasectomy
There is a surgery called vasectomy that is a method of contraception. The two vasa deferentia (Latin plural) are cut and sealed, so the sperm cannot get out of the body. This is usually permanent, but in some cases it can be reversed. Sometimes instead of cutting the vas deferentia, the surgeon puts something to block the sperm instead of cutting them.
