Congenital Bilateral Absence of the Vas Deferens – an Overview
... Congenital bilateral absence of the vas deferens (CBAVD) as a cause of azoospermia accounts for about 1% of male infertility (1). CBAVD is a recessively inherited condition that has been linked to mutations in the gene CFTR. CFTR mutations can also cause cystic fibrosis (CF), an often life-limiting ...
