The quality of the embryos is the same at the moment of freezing as once thawed, that is to say, they present the same morphological characteristics. What can happen is that, when they continue their development after a few hours, these may change. For example, compaction, multinucleation, fragmentation, etc., may appear, so the embryo would have to be assigned another category.
