- A quality embryos
- are very good quality embryos with greater pregnancy probability.
- B quality embryos
- their quality is good.
- C quality embryos
- D quality embryos
- are embryos of poor quality and therefore with little potential for implantation.
in this case, the quality is reduced compared to the previous ones.
