Inclusion criteria

Inclusion criteria: Use embryos for this study only when embryo development and morphologic evaluation achieve our standard which embryos can be vitrified.

Exclusion criteria

Exclusion criteria: When the growth of the embryos stop or when a morphologic evaluation does not achieve our standard that can enforce embryo vitrification, it is excluded from this study.
