1, the body is in an alkaline environment.
Biologically, the Y chromosome determines the birth of a boy. Studies have shown that Y chromosome prefers alkaline environment, so women who want to have boys should eat more alkaline foods during pregnancy, such as all kinds of vegetables, fruits, beans, milk and grains.

4. Women are rich in hormones.
When women's androgen secretion is more vigorous, it is more conducive to the combination of eggs and Y sperm, and it is easier to accept the androgen released by Y sperm, which means that such women are more likely to have boys. Such a woman is usually the kind of strong and decisive person.
5, the determination of ovulation time
Under abnormal conditions, X sperm has a large oval head, short and thick tail, slow swimming, good acid resistance and absolutely strong vitality. Its survival time is 2-3 days. Y sperm has small head, sharp shape, long tail, fast swimming speed, poor acid resistance and easy to be "frustrated". Its vitality is absolutely weak. Its survival time is usually within 24 hours. When these two kinds of sperm enter a woman's body at the same time, if a woman ovulates within 24 hours, the probability of pregnancy is equal. If she ovulates again after 24 hours in the same room, it will increase the possibility of giving birth to a girl.
