Hi, Welcome to HCM. I am Dr. Das
first of all your husband has normal sperm concentartion and count. But the motile sperm is very low. It should be more than 50%. this may be the cause of infertility
. I suggest that go for sperm viability test. And most importantly you both try your best to get a baby. I think in most of these cases pregnancy
may take a little time. But keep in mind that Only ONE normal motile sperm can cause pregnancy. so dont worry.
