Early on in our fertility journey I started comparing success rates using the CDC website. I had two different consultations with 2 different RE's and wanted to see how their rates compared. Right on the CDC website, it says do not use these for comparative purposes. You never know if one clinic is used to seeing "more challenging" women or harder cases versus easier ones. I know it is easier said than done
The number you quoted in your post actually seems VERY encouraging....I think my clinic was at about 26% and here I am pregnant. Also keep in mind each clinic has a different protocol for how many to transfer and at one stage (3 day, 4 day, blast, etc.) All of those things can alter rates greatly.
My best advice is that if you are happy with your RE, then stick with them.
Best of luck to you!
