Hello,Am at the moment due to start a fet..I have only one frozen blastysis left to use and am so worried about only having the one and hat it may not defrost in one piece.Has anyone any experience of this..thanks

I am right there w/ you...so just as curious as you are, and would love to hear how yours turns out. We are planning a FET transfer and have 3 frozen blastocysts. I keep feeling like I hear both ways...people on this forum that are successful w/ blastocycts def/transfers (which is very encouraging to hear) and then our clinic, which has a great success rate w/ their IVF/FET's has told me that we have about a 30% chance of them defrosting and making it...so I am curious to how it will all turn out. I am sure it does have to do w/ what SDScientist said, how the embryologist takes care of them!
GOOD LUCK to you!

I did an FET with one Day 6 blast.  The cycle was unsuccessful, but the blast thawed beautifully.  As long as it was frozen using vitrification then it should have a >90% chance of thawing okay.  Also depends on how experienced your embryologist is with the freezing and unfreezing technique.  Good luck.
