Patient's question:
A friend told me that he has now developed obvious blastocyst conditions. He has never heard of this before and feels quite curious. He wants to know if a blastocyst on the sixth day is of good quality.Doctor's answer:
A blastocyst refers to the newly formed infant after pregnancy. The difference between a blastocyst and a zygote lies in stability. Due to its short formation time, the embryo is less stable in terms of morphology and structure. The embryo contains fewer cells, meaning there are not many cells. The blastocyst is relatively stable, composed of a large number of cells, which can reach over 100, making it more stable. The embryo and blastocyst are two situations that only occur in vitro fertilization.
