Rate of blast from Day 3 Grade 1?

Question

I got 5 eggs, 4 fertilized, and all four are 8-cell Grade 1 Day 3 embryos! How many of your similar embryos at Day 3 made it to Day 5 blast and then to freeze?? Thank you!!

Answer

This is great! In our experience, whatever made it to day 2 lasted to blast stage. Our doctor said fertilisation depends on sperm, then day 1 was mainly about egg quality (my eggs were crappy quality and they fragmented early) and the next few days is more about sperm and egg together. Hope this helps. All the best! 
We are currently 5w3d on our second cycle. First cycle 17 eggs retrieved but non made it to day 6 😫 second cycle got 18 eggs, 1 fresh transfer and 2 frozen 🤞🏻👍🏻🙌🏻
