One of the key elements. As high-quality embryos, 4AA embryos have attracted widespread attention in their transfer success rate.

So, what is a 4AA embryo? 4AA embryos are a classification method based on embryonic morphology scores. Among them,"4" represents the development stage of the embryo, and "A" represents the quality level of the embryo. 4A

An A embryo means that the embryo has developed to the blastocyst stage and is of extremely good quality. In the process of IVF, what is the success rate of transplanting a high-quality blastocyst 4AA?

The environment is good, and the thickness is moderate between 8 - 12 mm. In addition, hormone levels, underlying diseases, genetic factors, etc. may also be successful in embryo implantation
