Feel bad for husband

So we recently found out that my husband has 1% morphology. Everything else came back good- motility and count, but morphology is very low. Long story short, my husband has Ulcerative colitis, lived abroad- and took medication for too long- which is what the fertility specalist believes caused the low morphology due to prolonged exposure to this medication. Theres nothing we can do to fix it. He's only 31 btw, i'm 26. 
My husband is the nicest man on the planet. He lived in Europe left his family, company- everything to be with me (in the US). Helps my family, does everything I've ever asked. Works hars, cooks me dinner-doesn't ask for much. Now as we go through this he is so upset, and feels like he's less of a man because it isn't happening(his words).  I get so upset every month that it doesn't happen, and I think that hurts him even more. I obviously don't mean to cry each time, i cant help it. I don't blame him, ever- but he is just so down and I don't know how to help. 😔
