I just had two blasts transferred on day 5. They weren;t expanding or hatching.
3 of the rest were frozen that were fully expanded. I had 15 on day 5, but only 5 looked good and 3 made the cut. Guess I have bad eggs.
My RE said the critieria to freezing a blast is that it has to be fully expanding on day 6 and I have read this as well on the SIRM website. It says and RE ..."If the blast is not fully expanded that it is most likely chromosonally abnormal. "
So my questions is..... Why don't they tranfer on day 6 instead of day 5. Tried to do a search and cant come up with any info.
Does anyone have any insight?
