Artificial inseminat: There is a way. You can recur to the artificial insemination where we can grow the fertilized egg outside and then insert it in your wife to let it implant and grow to a full baby. This is expensive and succeed in many couples not in others. You need to consult a trusted fertility clinic for full details.

Not uncommon: If all testing done, keep trying!
