IUI & low sperm morphology??

Stephanie • 12 mo daughter 💕 Due in August baby#2
Hi ! My husbands sperm count went from 8.8 mil to 105 mil! His wash sperm is 40million.. His morphology is 13% it should be 30% or higher.. My doctor recommended trying a IUI.. I also have PCOS
Have any of you ladies had a successful first IUI? Any male problems? I'm super nervous! She will be giving me femara and a trigger shot to boost ovulation before the IUI.
