Men with Cystic Fibrosis (CF) often lack a vas deferens due to the thick, sticky mucus characteristic of the disease. This mucus can block or damage the vas deferens during development, often leading to congenital absence. As a result, sperm cannot travel from the testes into the semen, which is a common cause of infertility in men with CF.

- Does the absence of the vas deferens affect fertility in men with CF? Yes, the absence of the vas deferens prevents sperm from traveling from the testes to the semen, often resulting in infertility.
