My husband is 41, i am 39, we have been pregnant 9 times in the past 5 years all have miscarried around 6-7 weeks. I have been checked out an there is no reason i can't carry a baby, i have 3 already, my husband has none and after much research i believe he has a motility issue, he has plenty of sperm but seems they aren't functioning properly. What do you recommend?
