It's huge. Is it accurate to say that fortune-telling boys and girls are born?

No, "of course it is determined by men, and sex is determined by sex chromosomes in genetic genes." Female sex chromosomes are made up of XX, while male sex chromosomes are made up of XY. In other words, when a person's sex chromosome contains Y, he is a man. "This biological genetic principle is correct, but there should be some external factors at work. For example, after receiving male sperm, the acidity and salinity in the vagina will affect fertilization. I gave birth to a girl, and the way to think about it is to eat more foods containing vitamin C. A friend of mine wants to have a boy, and he eats more salty food. In addition, he can wash his reproductive organs with dilute soda before sexual intercourse.

Hope to adopt!
