Cystic Fibrosis

This is one of the most common severe genetic disorders that occur in people of European origin. The carrier rate is about 1 in 24 persons of northern European ancestry.  Carriers are healthy and have no symptoms.

For a child to be affected both parents must be carriers. In this situation, the risk of having an affected child is about one in four.

Sperm banks generally perform carrier testing on their donors, but the majority don't test for every mutation.

If you are known to be a carrier for CF, genetic counseling is recommended.  Consult your physician for further information and inform the sperm bank about your situation.
