Patient's question:
My uterus has a clear cystic embryo condition, which I've never heard of before. It makes me quite curious, and I'd like to know if a blastocyst on the 6th day is definitely a girl?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 relatively stable. The embryo and blastocyst are two situations that only occur in vitro fertilization.
