It's all about the stats. I chose a clinic who published theirs on their website (Advanced Fertility in/near Chicago, if you're curious). I also looked at personal reviews on Yelp, Google, etc. My husband and I were doing embryos, not eggs, fyi.
I met with the head of the clinic. He gave it to me straight; my chances of a live birth using IVF were abysmal: 22%. [And that was before we knew Husband's sperm was wonky, too.] But, if we wanted to try, he wouldn't say no. So, no schmoozy optimism or up-selling. (They had at least one female doctor on staff, which I could've chosen. Also, the ultrasound tech was the same lady each time.)
I had NY-based health insurance at the time, and they DID cover all the monitoring, which was about $2,000.
During the process, it all went fucking terribly, and they only got 3 eggs from me. BUT, then our luck changed, and one turned into my 3-year-old daughter, another into my infant daughter, and the 3rd egg is an embryo on ice. Results not typical.
