I've been scouring the internet looking for success stories of FET's with 4AA and 4AB blasts and am not finding any. I guess I'm trying to figure out how much the success rates decrease when the blast is a 4 instead of a 5.
Honestly I'm not finding a lot of success with FET in general. My RE assures me that people do have success, but I'm growing skeptical. I have 4 frozen 4's and 3 frozen 3's. I do not want to waste my time if they are not going to amount to anything (not that we have a lot of other options at this point). Anyway, if any of you have success stories from FET with grade 4 embryos, I would love to hear them.
Thank you to you all.
