We met with my RE last week to go over the FET protocol. Seems pretty basic -- I'll just be on estrogen and progesterone. She told me they are seeing almost twice as many pregnancies with medicated FETs as natural FETs, so that's what we chose.
Things got complicated when we started talking embryos. We have 5, and they were frozen in pairs, so we have 2 pairs and 1 singleton. Since we are still planning on SET, the obvious choice is to thaw the singleton. She said that the embryos survive thaw 90% of the time, but if the singleton falls into the unlucky 10%, we'll have to thaw one of the pairs. If only one of the pair survive thaw, we'll just transfer that one. But if both of the pair survive, we have to decide whether to transfer both or re-freeze the second one. In other words, do we risk multiples -- which we've been really committed to avoiding -- or do we risk the other embryo? We would still have one unthawed pair left, but I was hoping to get a second pregnancy out of these embryos (although we only want 2 kids, so no second pregnancy necessary if we transfer 2 and both implant and are carried to term).
She told me embryos are less likely to survive the second freeze/thaw process, but not how much less likely. Does anyone know the odds for this? My Google search wasn't too successful.
All are A or B-grade blasts and were frozen using vitrification, if that helps.
Would love to hear what IF would do, especially from those who are also SETers!
Re: Embryo quality after 2nd freeze/thaw process?
Personally I would thaw a pair of embryos to ensure that at least one will thaw properly. If both do, I personally would probably put back both and risk multiples because I'd be afraid of losing the one we didn't put back.
This is a tough one but I think that's what I would do in your situation. I don't have any evidence or research to back it up but that's my opinion. GL with whatever you choose! It's a tough decision deciding how many to put back.

I don't know personally but....
A teacher I work with developed OHSS during IVF #1. It was so bad that they had to cancel the transfer and freeze all the emrbyos. She had something like almost 15-20 to make it to freeze (don't know the #, but something crazy). The first FET they did failed, the second from the batch worked and they now have a 2 year old, and now the 3rd FET from the same batch they put in 2 and she is now pregnant triplets...a singleton and identical set!
It's looking like my IVF #2 has failed, and we have 5 frozen...so I'm very curious about your question as I have no clue how ours froze! Did they tell you in the beginning or did you just find out?

They did not ask us how we wanted them frozen. Based on things I've heard on this board, it seems to be standard practice to freeze them in pairs.

We were told the quality of each embryo pre-freeze; we do not know at this point how well they will survive thaw but are just trying to figure out what we would do in any of the possible situations so that we are prepared. It only takes an hour or so to thaw an embryo from what I've read so the situation could change a lot that day and I want to be ready so I'm not making a snap decision.
I hope you're wrong that your IVF #2 has failed, but I'm sorry if it is a BFN. GL and thanks for your input!
