Patient's question:
I've been married for a year, and my husband and I don't have any children yet. We still have frequent sexual relations. Then, after checking at the hospital, it wasn't my husband's fault but mine. I've been very distressed about this and am planning to undergo in vitro fertilization. I want to know what the difference is between an embryo and a blastocyst?Doctor's answer:
From the perspective of the time and degree of cultivation, the fertilized egg formed through in vitro fertilization develops for two to three days to form the stage called an embryo. The difference between an embryo and a blastocyst also lies in stability. Since the formation time of an embryo is relatively short, its morphology and structure are not yet very stable. This is because the number of cells in an embryo is relatively small, meaning it is composed of fewer cells. A blastocyst is relatively more stable, as it is composed of many cells, which can reach over a hundred, making it relatively stable.
