10 Symptoms of Cystic Fibrosis

4. Difficulties in Conceiving Children

Cystic fibrosis often causes trouble when attempting to conceive. For men, this difficulty is physical, because they don't have the canal that connects the testicles to the penis, the vas deferens. Because sperm cannot travel, they are essentially shooting blanks. This occurs in around 98 percent of men with cystic fibrosis. Women with this condition may find that the mucus that the condition generates blocks up various parts of their body. If the mucus forms in the cervix or the fallopian tubes, it can prevent sperm from physically interacting with the egg, a process that's required for conception.
