Don't assume you're infertile just ask "guywithcf". Infertility in men due to CF it could be structural like incomplete vas deferens where sperm cannot join with seminal fluid. This means your ejaculate has no sperm hence no little Enzo's. Your sperm quality, quantity and your seminal fluid carrying your sperm should be looked at by a urologist when you're considering children, or now if you wish to know.
You have the same potential for IVF taking sperm from your testes just as eggs are removed for fertilization and implanting in the uterus. All this means that you have a good chance of fathering a child someday. A lot of science is descending on reproductive health care and like your genetic testing, if you and your future wife wish, she can have the same genetic test. With luck, any children can be CF free.
