Male infertility (motility)

Been ttc for over 3 years now. We’ve done a lot of test over the last couple months and found out it’s my husbands sperm motility 😢 His sperm count is very high but his motility is only at 6% and his testosterone is very low. His urologist prescribed him clomid and cialis and told us to come back in 3 months (which seems forever away 😭😭)

Has anyone else had this problem?? Any other life style changes we should try?? We’ve cut caffeine out completely.

He’s so stressed over it and I know that’s not helping at all and idk what else I can say to him to make him feel better about it. 😔😢

ANY ADVICE WILL HELP..

I’ve spent the last 3 years thinking it was me the whole time and I have not done a lot of research on this problem yet.
