Patient's question:
I believe many people hope to have a son, so let's talk about whether it's the X sperm or the Y sperm that determines the gender of a child, and which one swims faster, the X sperm or the Y sperm?Doctor's answer:
If the X sperm has higher vitality in the male body, it is easier to have a girl. If the Y sperm has a higher survival rate, it is especially easy to have a boy. Generally speaking, there is no relationship between the survival rates of X and Y sperm and the male's physical condition. Their dietary nutrition, environmental, geographical factors, and others have a great relationship. If the fetus is female, if the Y sperm combines with the egg, it gets a pair of chromosomes, which is XY, and the fetus develops into a male.
