In the reproductive system, embryos and eggs naturally have a protective protein shell called the zona pellucida (ZP). How compacted a morula becomes through this merging process is important for morula embryo grading. We can see how age plays a role in the graph below, based on the Awadalla et al.

Correlation between standard blastocyst morphology, euploidy and implantation: an observational study in two centers involving 956 screened blastocysts. Embryos that have undergone hatching prior to biopsy have been shown to have improved IVF outcomes in comparison to non-hatching embryos. Trophectoderm biopsies were performed on Day 5 (d5) or 6 (d6) for embryos meeting morphology eligibility criteria (set at 3BC).

We found no evidence of altered IR or other clinical outcomes in the transfer of FH euploid embryos. It was just a way to avoid embryologists from thawing the wrong embryo because a 4/4 (good quality 4 cell embryo) might be confusing to some newer people who might want to thaw and transfer that over a 2/6. Bromer JG, et al. The Miracle of Life: Unpacking the Hatching Blastocyst Eggs can be fertilized by conventional IVF or by intracytoplasmic sperm injection (ICSI). This was reduced to <10% with <5 cells, or about 10% with >25% fragmentation. She said they go into the thaw with a protective barrier (can't remember what it's called) And they will make a small slit in the barrier to allow for the embryo to break through and implant.
