Well, here they are! Our embryos!
the one on the left is the male and the one on the right is the female.
If anyone cares, the one on the left is graded 6AA, and the one on the right is 3AA.
The grading system represents three values:
1. Blastocyst development stage - expansion and hatching status
2. Inner cell mass (ICM) score, or quality
3. Trophectoderm (TE) score, or quality
1. The first number refers to the degree of hatching. 6 is fully hatched, and 3 is hatching.
2. The inner cell mass - can be rated A, B, or C. In our case, they were both rated A for "many cells, tightly packed"
3. this one can be A, B or C as well, and A refers to the shell on the outside of the embryo which will become the placenta it has "Many cells, forming a cohesive layer" which gives it an A.
Ok, how's that for your embryology lesson?
