6.35m/mil Sperm Count & 26% Motility

My husband and I are pretty devastated. After being off birth control for two years and actively TTC for 15 months, we finally got these results. I don't have any issues. He's been on Fertilaid + Motility Boost for about a month now. Anyone with similiar numbers ever conceive naturally? I'm feeling like IUI or IVF is our only hope now.
