Day 3 Embryo Cell Development and Success Rates
Grading on day 3 of embryo development is based on the number of cells in the embryo (with more cells generally being better) and the appearance of the cells. Embryo grading helps medical professionals determine which embryos are most likely to develop successfully and choose which embryos will be transferred to the uterus during IVF.

What is embryo grading? Day 3, Day 5, Success Rates
2023年4月10日 · Generally, the embryo’s quality is determined on day 3 or Day 5 after egg retrieval. The reason is that until day 3, most of the embryo’s growth and development relates to the egg contents. From the end of day three onwards, the genome of the sperm enters the embryo’s DNA, and the embryonic genome is activated.
