Help from IVF'ers needed

I've been thinking more and more about the IVF process which includes thinking about the clinic I'm currently using.

I'm not unhappy with my clinic all but, since I'm moving on to IVF, I want to make sure I'm going with a place that will give me the best shot at getting pregnant.

The truth is, we chose our current RE because we were going to be paying out-of-pocket for IUI and price was a major factor. And, let's be honest, you don't have to have graduated first in your class to do an IUI.

But, now we have insurance that will pay for IVF and it's something that requires so much more precision than IUI. We need to know we have access to the best option in our area.

So the question to my readers is this: what do you ask when you're interviewing RE's?
How do you make comparisons beyond the typical "success rate"? I don't want to rely solely on success rate statistics because too many contributing factors go into that figure.

I know there are clinics who won't treat women over a certain age, or BMI or AMH/FSH level because they don't want their success statistics to be diminished.

My currently clinic is honest with you about the odds of getting pregnant based on your personal situation but they don't turn women away because the likelihood of it working are minimal.

What data do I use to compare clinics?
How do I know if they have a good assisted hatching program?

Please, any information or guidance you have regarding this would be immensely helpful.

Thank you in advance!
