Low sperm motility??

TTC #2 & husband had a sperm analysis done because we are going on 10 months of trying & the results came back that he has lower sperm motility than he should. It’s not considered low, but it’s on the lower end of normal. I just ordered him some Fertilaid & motility boosters. We are going to start using pre-seed again too. Anyone else have any other ideas or have had this problem before too??
