This type of classification corresponds to a blastocyst of excellent quality, with an internal cell mass and a good looking trofoectoderm. It has a high implantation capacity and, therefore, a high probability of giving rise to a pregnancy. However, there is no guarantee that a woman will become pregnant. The fact that the embryo quality is good has a great influence on the implantation, but other factors such as the state of the endometrium at the time of the transfer, the age of the mother or the cause of infertility are also affected.
Will AA quality embryos always lead to pregnancy?
