Best grade for embryo?

Question

Hello ladies, wondering what the best grade for embryos are? I had my retrieval a few weeks ago and thankfully a good number of eggs were retrieved and fertilized. We have a range of different grade embryos best being a 4AA. The nurse has said that that’s a good quality but I was reading 5AA might be better? Does the grade determine how it implants/ how long it sticks? Just a little worried as I have my FET coming up soon! Thank you 🙏

Answer

Not sure, we got 10 embryos of course some better grades than others. Started off transferring the best grades but my first transfer was unsuccessful, second was successful but ended in miscarriage and my most recent transfer we transferred two one of them being a lower grade and both have stuck Im currently 9w5d and hoping they make it earth side ❤️❤️ I honestly don’t even know the exact grades of my embryos but have heard so many stories how people got their baby from the lower grade embryo rather than higher grades.

Answer

My son was a 4AA. My last embryo was a 5AA, currently 6w3d. AA best quality. 4 refers to fully expanded. 5 is hatching and a 6 would be fully hatched

Answer

4AA means fully expanded with perfect grade for traphectoderm and inner cell mass. 5AA is hatching embryo and 6AA is fully hatched embryo.

Answer

4AA is a great grade from my understanding. 5 might just mean slightly more expanded?
