📌Understanding Embryo Grading ‼️💯 ————————————————————————Why is it done❓
🔹Because embryo quality is one of the most significant factors.
🔹To ensure that only the embryos of viable quality are considered for transfer.
What happens when your embryo is of poor quality❓❓
🔹Poor embryo quality will most probably result in a failed cycle due to implantation failure.
🔹If pregnancy does take place, there are high possibilities of fetal abnormalities, miscarriage, or other birth-related complications.
🔹Embryos are transferred on day 3 (cleavage stage) or on day 5 (blastocyst stage). ———————————————————————-
◾️Cleavage Stage Embryo Grading:
————————————
Embryo grading is done on the basis of these parameters:
▪️Number of cells in the embryo: preferably 7-10 cells ❕
▪️Appearance of the embryonic cells: cells should be of a similar size ❕
▪️Degree of fragmentation: little or no fragmentation ——————————————————-
✔️Embryos with Grade 1 to 2.5, with a minimum of 6-7 cells, are regarded as the best for transfer as they have optimal chances of growth and implantation. ❕❕
◾️Blastocyst Stage Embryo Grading:
————————————
▪️Day 5 embryos experience rapid cell division and growth.
These embryos are assigned grades according to the quality of Inner Cell Mass (ICM) and Trophectoderm Epithelium (TE). ❕❕
A: excellent quality
B: good
C: fair
D: poor quality
❕❕
🔹Embryo grading gives a fair idea about the quality of embryos and embryologists can choose the best embryos to be used for transfer.
🔹There have been many cases of when embryos with mediocre grades have resulted in healthy pregnancies and grown into beautiful babies.
🔹Even though embryo grading might be considered subjective, its reliability cannot be questioned because it helps in maximizing IVF success rates.
