Poor morphology-IUI?

Hey all. After a long 2 yrs of TTC we finally got a semen analysis done for my husband. (Could’ve been done in March but THANKS COVID!) he has the poorest morphology you can have, but he has a ton and motility is great. Has anyone had to do <a href="https://glowing.com/glow-fertility-program">IUI</a> for this or straight to <a href="https://glowing.com/glow-fertility-program">IVF</a>? He’s taking a ton of fish oil to help this issue hopefully in a natural way but I’m not banking on it.
