IUI question

Ana

Had another appointment today with the fertility doctor, he is giving me a higher dose of femara 7.5 (letrozole)...

We are doing an iui as well when I’m ready!

My question is: they want to freeze my husband sperm to do the IUI, but can we go in the same day so they don’t have to freeze it?

Can someone explain that process/steps to me before and after the IUI?

I’m so lost!
