So all my rambling, stressing and decision making the past few weeks just went out the window.
Well, we did decide. We decided to test, which would ultimately mean transferring only 1.
Then the embryologist emailed me the following:
I understand that you have questions about performing CCS on your frozen embryos. There are 5 blastocysts remaining from your cycle 10/08/13. These blastocysts were fertilized with a conventional insemination and cannot undergo CCS testing.
After a conventional insemination, even though only one sperm fertilizes the egg, there are thousands of other sperm which remain attached to the shell of the embryo throughout development. Because of the abundance of sperm still attached to your embryos, there is too great a risk of contamination during the CCS process; i.e. we may end up testing the DNA of the sperm rather than the DNA of the embryo.
Who knew?? I didn't. I guess I never had reason to ask before since we used donor eggs and thought we would be transferring them to me.
So thank you all for your support, advise and well wishes on this subject this past week. Now we're back to deciding between transferring 1 or 2 unknowns. Plenty of time for that decision. We still need to get through medical clearance for my gestational carrier.
Stay tuned...I'm sure I'll be stressing over something else soon enough.
