Patient's question:
My good friend is 25 years old this year. A couple of days ago, he told me that he has now developed obvious signs of a cystic embryo. He had never heard of it before and felt quite curious, wanting to understand what a cystic embryo is.Doctor's answer:
Hello! According to the described situation, this is a period during pregnancy. The blastocyst stage refers to the phase when the egg has just been fertilized but has not yet implanted in the uterus, at which point the embryo is called a blastocyst. The formation of the blastocyst is the result of cleavage, and by the 11th to 12th day after fertilization, the process of implantation of the fertilized egg is completed. Fertilization occurs within 12 hours after ovulation, and the blastocyst stage is during this phase.
