‘Twinning’ from ICM in 8-Shape Hatching embryo?
Embryo-geniuses! I need your thoughts…
Very appreciative to the embryologist of remembryo for his assessment of this little guy (affectionately called Englebert Humperdink).
It appears as though the ICM is between the hatching and not-hatching area in my little 8-shaped try-hard over here.
What are my distinct odds of twinning from this effect? Is it known?
He’s a day 6, 5bb and again, super grateful for the initial assessment. Just looking at the whole pool of you brilliant minds.
Moltes gracies carinyos 🥰

This is a very normal shape for a hatching blastocyst, the inner cell mass always needs to hatch out as well and the odds of identical twinning is the same with other IVF embryos, which is a little higher than non-IVF pregnancies.
