Chemo

So my fiancé and I are trying to get pregnant, I have two kids from a previous marriage and he has three so we both know we can make babies. He actually has been threw chemotherapy and was told it could cause him to be sterile we haven't been to see a specialist yet we wanted to try a little while longer until we took it to that step. I was just wondering if any of you out there have been threw something similar and what your out comes where. Thanks in advance any advice or comments would be great!!
