Questions on ivf

For those that have done <a href="https://glowing.com/glow-fertility-program">ivf</a>, do you have to get any testing done (I know men’s Swimmers) but if you have been ttc for awhile can you just jump to <a href="https://glowing.com/glow-fertility-program">Ivf</a>? Or so they make you do months of testing? I have a consultation with a fertility clinic this week and am unsure what questions to ask.
