We are gearing up to do a FET this cycle and I have so many questions! There is no formal literature at the clinic so I'm curious to know of your outcome, or outcomes of those you know that cycled at AART.
Embryos / blasts were frozen using the slow freeze method in 2012 and prior. I'm slightly upset they transitioned to vitrification for freezing the year after we cycled, as I questioned this so many times and we would have waited, given the awesome outcomes for thaw rate, and pregnancy success with a vitrified embryo / blast.
Anyhow - getting off topic!
I've been told loosely that success with a slow-freeze blastocyst is about 20%.
I have 4 frozen blasts. 19/20, 18/20, 15/20 and 14/20. I really can't decide if we should transfer 1 or 2. If the freezing was done via vitrification, then we would only choose 1. But, because it was slow freeze - and the success rates are much lower, I am torn over transferring 1 or 2 . . .we would like to reduce the risk of multiples but still achieve a positive outcome . . .
Any insight? If you did a FET, how many did you thaw, how many survived, how many transferred and what was the outcome? You are welcome to share your age if relevant (I'm in my early 30's, my siggie is outdated).
