Most men with Cystic Fibrosis (CF) are infertile because of a blockage or absence of the sperm canal, an alteration known as congenital bilateral absence of the vas deferens (CBAVD). Since the sperm are unable to make it to the semen, it is impossible for them to reach and fertilize an egg with intercourse.
