I'm wondering if anyone has any information on the relation of cell recovery rate after thaw to live birth rate in a FET. I can't find any information on this online except a general statement that a higher rate is better. For example, if you thaw 3 embryos (blasts) - all great quality - and there is a 60-70 percent cell recovery for each blast - is this a bad sign that they are not going to take? My first FET with my OE, the lab had an excellent cell recovery rate - 100 percent for two blasts and 85- 90 percent for the other two. That FET didn't work. For my DE cycle, the new clinic I'm using had a lower cell recovery rate (60-70 percent for two blasts) and I'm concerned that may have contributed to the BFN, but I'm not sure. I know you want to look at the embryos to see how they are continuing to grow after thaw before transfer and that tells something about their health. Thanks!

I do not have any stats, just experience.

We thawed a 9-cell that was frozen two years prior on day 3. It reduced down to 7-cell. I am now 11 weeks pregnant.
RE said this FET had a 40% chance of working. It did.

The embryo came from an original batch of embryos that gave us twins.

I really think you just never know.

Sorry about your bfn. Better luck next round!
