Congenital Bilateral Absence of Vas Deferens

What Does Fetal

Congenital Bilateral Absence of Vas Deferens?

Congenital bilateral absence of the vas deferens (CBAVD) is a condition in which the tubes that carry the sperm out of the testicles, called the vas deferens, do not develop properly and are not formed at birth.

CBAVD greatly impacts a man's fertility because sperm cannot be transported from the testes to the ejaculate, meaning the affected couple will be unable to conceive naturally. This complete lack of sperm in semen is called azoospermia. However, men may have normal levels of sperm in the testes.
