Male Infertility - supplements?

Caitlyn • IVF cycle under way for baby #1 ❤

I'm curious.. if any of your SO suffer from low sperm count, but all other numbers are good. Is he using any sort of supplements like fertileaid or simply a men's multivitamin? Currently finishing out 1 month of fertileaid but wondering if it's worth buying again or just using a multivitamin or trying something else completely. Let me know your thoughts! :)
