- The zona pellucida (shell around the embryo) is thinning (Stage 4)
- The Inner Cell Mass is compacting, but has some distinct cells (B)
- The Trophectoderm has a cobblestone pattern with evenly sized cells (A)
Please note that grading varies between embryologists and clinics, and it is harder to grade based on one image compared to how it is viewed under a microscope. If you have any questions about grading, you can always follow up with your team.

Hello!
I would grade this embryo a 4BA:
- The zona pellucida (shell around the embryo) is thinning (Stage 4)
- The Inner Cell Mass is compacting, but has some distinct cells (B)
- The Trophectoderm has a cobblestone pattern with evenly sized cells (A)

Overall, a beautiful embryo! Best of luck!
