How old were the embryos when they froze them? Were they only 3 days old? I see you have 3 frozen. It’s a little harder for me to give you any advice if they were only 3 day embryos. My clinic only freezes “great” and “good” 5 day blastocysts. So ultimately any frozen embryo is still gonna be a “good” embryo. If yours are day 3, one way to see if they’re “good” embryos is to defrost them, then “challenge” them, meaning, try to grow them out to 5 days and see if they become blasts. If they do, chances are they’re decent embryos to try. Problem is, you risk them all arresting before day 5 and have no transfer at all. I doubt your doc would want to risk that and would probably recommend putting them back immediately. At that point I can’t begin to give you success statistics. Your doc is probably right with 20%. I still don’t understand why clinics even freeze day 3 embryos. Cause you’re unsure with the chances. Like I said before, my clinic’s success rates with frozen are as high as fresh, mainly because of what I just mentioned. Continue your research, and I know that you’ll make the right decision. Just may take a little soul searching! I wish you only the best!
