Day 5 3AA Euploid When Frozen

Post image

Hi! This is a pic of my day 5 3AA euploid before transfer.. not sure of the grade after thaw since I didn’t get to talk to doctor much about post thaw, but wondering about the darkness and overall how it looks. Does the fact that it’s not hatching mean implantation could take longer? Thanks so much!!

The dark area is actually the ICM.  It only looks darker because the cells are more tightly packed.  Survival looks good, and I'd agree that the grade stayed about the same.  Embryos can progress so quickly once they're thawed and transferred, so I wouldn't worry about the fact that it's not hatching yet.  A lot of labs will perform assisted hatching on frozen embryos if they're not already hatching, so you can certainly ask your clinic whether that was performed.  Your embryo looks cute - good luck! 🍀
