Patient's question:
My sister went to the hospital for a check-up today, and the results showed a 4AA blastocyst. Is a 4AA blastocyst a boy?Doctor's answer:
After a woman becomes pregnant, many people want to know as early as possible whether she is carrying a boy or a girl. In fact, fetal growth and development require a process. Under normal circumstances, external genitalia only begin to form after four to four and a half months, and at this time, examinations such as color Doppler ultrasound can reveal the sex. During the gestational sac period, the external genitalia have not yet developed, so color Doppler ultrasound will not reveal the sex of the fetus. Showing a 4aa blastocyst does not indicate that it is a boy.
