Spina bifida

My husband was born with spina bifida, he isn't wheelchair bound nor does he have any problem in bed. However we've been ttc for awhile now with no luck. I just looked into it and found out most men with SB are infertile. I'm not sure if he already knew but I'm feeling really low now. I know there are other options out there but I feel hopeless. Is there anyone else in the situation?
