CBAVD

Congenital bilateral absence of the vas deferens (CBAVD) causes male infertility and may occur in those who have cystic fibrosis or in isolation. CBAVD refers to the improper development of the tube through which sperm are released from the testes. CBAVD is present at birth, but most men do not become aware of it until they have difficulty with fertility. CBAVD accounts for 1 to 2 percent of male infertility, and 98 percent of men with Cystic Fibrosis are born with CBAVD. Men with CBAVD have a number of options to help them conceive with their partners... see your doctor. DNA Direct offers genetic testing for men with CBAVD. The cost is $260.
