Azoospermia success stories?!

Hey y’all! So my husband has had two semen analysis’ that both came back with no sperm to be found (azoospermia)...we go back in 2 weeks to do a special analysis where they centrifuge the sample and look under a very powerful microscope to see if there are any sperm to be found...we’re hoping they’ll find some that way so I was just wondering if anyone else has experienced the same thing?? Our fertility specialist said IVF is going to be our only option so we’re looking for any success stories you all have to share! We are extremely blessed that my insurance fully covers IVF, so we are prepared to exhaust all options in hope of starting our own little family. Any feedback is welcome!
