Low motility and morphology problem

Es

Hello girls, we ttc about 6 months and it hasn't happened yet. I went to dr to check myself and everything is fine with me. Doctor wanted from my husband a semen test. So he did. Test showed he has 16 mil sperm count, 0 prograssive motility (total motility is 50), and 2% normal morphology. I am 29 and he is 33. He started to use some vitamins and eat fresh food.

What do you think about us to conceive with natural ways? Is there anyone in this situation and get pregnant without treatment?

Thanks in advance.
