Hi Carole-
I have two frozen embryos from my last cycle, both hatching blasts, one frozen on day 6 and one on day 7. Both embryos are XX and characterized as normal euploid by day-3 CGH. The day-6 is graded as B/A/A and the day-7 is graded as B/B/B (where A=best, C=worst, and the three grades are inner cell mass/outer cell mass/fluid-filled cavity).
My RE has given me an estimated success rate of 40-50% with each one in an SET. However I have been looking around at research and I have seen some studies claim that embryos frozen after day 5 do not fare as well. I am concerned that he may be overestimating my odds, in particular for the day-7 embryo. If I do an SET with the day-6 embryo that fails, I don't want to be going in with poor odds on another SET with the day-7.
I saw your other post regarding vitrification and to be honest I am not sure what technique my lab is using, but I would assume they are using the latest method as their FET success rate for age<35 is 53%. I will confirm this on Friday, and will also ask my RE if they have had success with day-7 embryos. But I am very interested to hear your thoughts on this also. Thank you so much!
