Cystic Fibrosis Testing and the R117H Gene?

My doctor just called and I have test positive as a cystic fibrosis carrier. We are still waiting on the results of my husband’s test. On top of this I have a mutation in my gene called a R117H. He said it may cause sterilization if this is a boy. I am having trouble finding any information written in lay men’s terms. Does anyone know any additional information? Has anyone had this? What is the likelihood that this will cause sterilization if it is a boy?

Thanks so much. I am trying not to worry, but I would like to be informed before they send me to a specialist…
