5 Facts About Cystic Fibrosis and Reproduction

1. Most Female CF Patients Have No Problems Conceiving


According to the Cystic Fibrosis Foundation, cystic fibrosis (CF) affects the reproductive system, but most women have no difficulties in getting pregnant. Female CF patients have a thicker cervical mucus caused by the defective functioning of the cystic fibrosis transmembrane conductance regulator (CFTR) function. The thicker mucus can make it more difficult for the sperm to penetrate the cervix, increasing the amount of time needed for a woman to get pregnant. But in some cases the difficulties are related to other problems, not CF.

According to the Cystic Fibrosis Foundation (CFF), most CF female patients don’t have problems getting pregnant and have healthy pregnancies, with 85 percent of couples reporting they were able to conceive within the first 12 months after stopping contraception.

    I’ve never heard the term sperm canal used before. The vas deferens, which carries sperm from the testicles through the sexual anatomy, is usually absent at birth for men with CF. The seminal vesicles may also be smaller or absent.
