“Unexplained Infertility” Experiences?

Hi everyone. I’m starting my very first IVF cycle in about 2 weeks. I previously did 3 rounds of IUI with no success.

Looking at the posts here, I guess you could say I’m getting a little discouraged.

I was just wondering, for those who were diagnosed with “unexplained fertility”, all tests (you and your partner) came back normal, you don’t have any other conditions (like PCOS), what was your experience? Did you have a high number of egged retrieved and a high number of embryos developed? Did you happen to discover something about your “unexplained fertility” during your IVF journey?

Thank you!
