Patient's question:
How can I have a boy? Hello! I want to consult about having a second child and wanting to have a boy. My daughter is now in kindergarten, and my mother-in-law keeps nagging about having another grandson. My husband and I have discussed it, and we plan to have a second child. I want to know how to have a second child and want to have a boy?Doctor's answer:
Gender depends on sperm, not on the egg. When sperm and egg combine, whether it is an X sperm that binds first or a Y sperm depends on their "luck." The chances are equal. After the sperm and egg combine to form a zygote, there are two possible outcomes: one is that an X sperm combines with an X egg, resulting in an XX type and giving birth to a girl; the other is that a Y sperm combines with an X egg, resulting in a XY type and giving birth to a boy.
