IUI questions!

Has anyone done IUI with super O, for male factor, low sperm count (14mil and low morphology 2%) any success if so how many times did it take? My husband starts the fertile aid today when it comes in so hopefully that help, and I am doing an HSG in two weeks to hopefully help our chances and starting IUI in November.

Also can you explain how the IUI process works, days most like have to go in, I know it’s different for everyone but getting and understand would be great!
