OP here- I am at shady grove. My first PGS normal i transfered thawed to 95%. This one was 85-90% so I am not sure it matters much. I asked another doctor at a different clinic and he told me its really just a guestimate.

MY first child I never got this info at my old clinic, he could have thawed to 80% for all I know.

I think this may depend on your lab quality. I am at SG, and think their lab is great, so had no concerns. We had 2 failed FETs, thawed and then re-froze all embryos for PGS testing, and I got pregnant on next transfer with a PGS normal embryo that thawed 95%. Even the double freezing and thawing did not affect my embryo. No regrets at all. I wish I had done it after retrieval and possibly could have avoided my first 2 negative transfers.

I'm not sure what you mean. What do you regret and what is your same result?

I had two FETs one with a PGS tested embryo and one without they both had a thaw rate of 95%.

I regret it no because I think it damages embryos but because I'm having the same result regardless.

I'm the poster you mentioned. My doctor told me the risk is very very small and even if this did happen it wouldn't happen to all embryos.

I think the benefits of pgs out weigh that risk.

I'm at SG. For my first FET, I don't think it was mentioned. For my second FET, they did give the number. I mentally freaked out a bit, even though it was 95%. I was wondering what happened to the other 5%!

I think it depends on the clinic. At my old clinic where I had my first I never got this info. Now they told me 85-90%. It was a PGS tested embryo. I am not sure I needed this additional information to stress over.

+1. Had a PGS normal transferred, but only thawed to 80%. It was a BFN. Super upsetting

I had one thaw at 80% and my RE later told me that 80% was not that great. My other embryos were 90-95%.

Not sure the medical answer, but anecdotally (for what it is worth), we transfered one at 89% or so--doctor later that week told us that if he had known (he was on vacation) he would have thawed another and trasfered two. DD is 17 months and wonderful.

That being said, if you have concerns definitely ask about it before hand. I didn't even know really about thaw rates before my FET because I had only done fresh before.

How significant is this number? Is there really a large difference between 85%, 90% and 95?
