Hey there, I can't say I'm in the same position, my husbands morphology was 10%. BUT I did do a bit of reading on the topic (because I'm a worrier and we have unexplained infertility so I've researched a little bit of every thing) and found that morphology below 4% normal forms can make it more difficult to get pregnant, but not impossible. To be honest, researchers/docs just don't know how much of an impact morphology has. The degree of fragmentation within the dna of the sperm would be a better indicator of fertility. I would say keep doing what you're doing! Keep trying! If you have already tried IUI and it hasn't worked then IVF with ICSI might be a good option for you! 0% morphology is not insurmountable!
You can also look into male supplementation before that point (although I'm honestly not sure how effective it is). Get him on coq10 400mg at a minimum and reduce/eliminate some of those poor lifestyle choices (alcohol, smoking, baths, etc.).
There is a good chance that you'll get to where you want to be! It will just be a longer road than most have to take.
