1% morphology and recurrent miscarriages

I had 3 miscarriages at 6 weeks in a 7 months span. My husbands SA came back yesterday, everything good except 1% morphology. He has an appt with a fertility urologist in 2 weeks.. but has anyone else had pregnancy losses associated with low morphology? I can’t find anything. I keep seeing people not able to conceive because of it, but we have not had a problem with so many pregnancies in a short time. Does this indicate something?
