Borderline normal morphology for husband semen

Gina
Hello all. We had my husbands sperm analyzed yesterday. Everything was above normal. Except he has borderline normal morphology. It falls at 5. Does anyone have any experience with this?? Could this be why we haven't gotten pregnant. We had a baby together five years ago. And we weren't trying. But now we have been trying for over a year with one chemical pregnancy. Any help would be appreciated
