2PN frozen embryos success

Can someone please tell me what is the success rate of  thawing of frozen embryos  from ICSI that are at  pronuclear stage. Does anyone here went through the transfer successfully? Thank you.

I had 19 embryos frozen 2pn.  The problem with them is they don't know how healthy they are at that stage.  I was lucky enough to get prenant the first time from 3 of them....but unfortunatly miscarried.  I did 2 other 2 day transfers, bfn... my new RE thawed out my remaining 7 embryos, and only 1 made it to day 5, although it was behind and didn't make it to blast.  The point is, only a few of them were strong enough for pregnancy, but we didnt know that because of how they were frozen.
Do you know why they froze them on day 2?  My advice to you would be, to tell your RE you want them thawed at least long enough to do a 3 day transfer... or a 5 day transfer... You do not know the quality you are getting, if you transfer 24hrs after thaw. (if that is his plan).
You can end up spending alot of unnecessary $ on transfers (which I have found out the hard way).

I had 2 embryos frozen 2pn when I was 38 years old.  It was the highest dose IVF cycle possible.  When it came time to plan the FET a few years later, my RE gave me a 30% chance of pregnancy if they thawed.  They both thawed (grade 1, 4 cell embryos, which RE told me is great) and transferred both of them.  GIven how good the embryos looked, my RE said 30% chance "might be conservative."  4 more days until my pregnancy test...

Mellissa, so did you get preg with the transfer. At my RE they usually do a day 3 transfer. So that the chances are more for pregnancy as some embryos stop growing after day 3.


Allip- During my 2nd IVF cycle in 2008, I had 3 day 3 embryos transferred and I got pregnant and my son is 15 months now. Had 2 2PN frozen, they thawed yesterday morning and
luckily they survived and today morning was the transfer. They were 5 cell. I hope they work. Have to go for pregnancy test on Nov'2. Good luck to you..:) keep us posted.

Maria2707, how wonderful that you've had such great success and it sounds like you will again!  I didn't know 2PN cells could grow to 5 cells, I thought 4 was the max.  I'm glad I didn't know that when they transferred them! :)  As of right now, I'm still pregnant (first beta test today was 167).  Good luck on Nov 2!  That's 2 days before my first u/s assuming my beta looks good on Thursday.
