I'm 42 years old and did my egg collection this month.
Of 17 eggs retrieved, 15 was matured, 14 eggs fertilized
Day 3 > 8 cells, grade 2 = 8 embryos
8 cells, grade 2 = 1 embryo
6 cells, grade 2 = 4 embryos
3 cells, grade 2 = 1 embryo
Day 5 only 3 went to hatching blast stage with grade BC
I saw on many forums that the TP grading, which is C matters most for implantation and a live birth. Would be great to hear any success stories of anyone having a FET with a BC grade embryo.
