The story of an embryo !

We retrieved 4 oocyte cumlus complexes from 4 follicles for this older woman with a very low AMH level
All the 4 eggs were mature ( M2) and we did ICSI for all of them
However, only 1 fertilised
This divided well until Day 4, by which point it had formed a morule
However, the blastocyst on Day 5 was of poor quality

This photo-essay emphasises how much biological variability there is in egg and embryo quality, which is why it is so hard for us to predict the outcome of any IVF cycle
