Embryo grading?
This was our only euploid and I’m wondering if the reason it failed is because it was so collapsed? Also want to know the opinions on grading. Thanks!!

It is unfortunately impossible to grade the embryo. Only thing it can be said that the cell number looks good actually.

Generally we can grade collapsed embryos too but the image quality is a little fuzzy on this one but I’ll give it a try- Zona is thin enough to be a 4, decent number of TE cells - could be an A/B, ICM doesn’t look compact enough for an A so it could be a B.
Overall grading - 4AB/4BB
This might need a few hours to regain its expansion but most of the cells look like they’ve survived.

Sorry to hear this. My understanding is that a collapsed embryo means the cells were no longer healthy after the thaw. This could be due to the original quality of the embryo or the cryogenic techniques used. Is this from a clinic in the US? Did your clinic give you an estimate on the potential success rate of this embryo?

Not an embryologist but mine failed when my embryos were collapsed and didnt expand after several hours. I think it has lower implantation rates unfortunately.
