It is better for Chinese medicine to regulate the warm palace and replenish the body. Of course, it helps to give birth to boys, but it cannot guarantee the birth of boys. The key to fetal sex is male X and Y sperm. X-type sperm likes acidic environment, with weak activity, slow action and long survival time, while Y-type sperm likes alkaline environment, with strong activity and fast swimming, but short life. Therefore, according to these characteristics, people try to achieve the goal of controlling sex through artificial methods. The specific method of giving birth to a boy is as follows:

1) diet control method

Eat more alkaline foods, or foods with high potassium and sodium content, such as sweet potatoes, potatoes, fruits, chestnuts, soda biscuits, and snacks without cream, and the chances of having boys are very high. The adoption of diet control should start one month before the birth of a child, so that an alkaline environment will be formed in the woman's body after conditioning.

2) Change the pH of vagina.

Lincar natural calcium was taken three months before pregnancy, 4 capsules a day, without interruption, and it was not stopped until pregnancy.

3) master the ovulation period

By measuring the basal body temperature and mastering the ovulation time, it is generally easy to have boys in the same room near the ovulation time.

4) Control the number of sharing rooms.

If the number of sexual intercourse is not much, the amount of sperm injected each time will be more, and the chances of having a boy will be greater.

5) Master the time and depth of ejaculation.

If the man ejaculates when the woman reaches orgasm and at the same time ejaculates around the woman's cervix, it is easy to get a boy.
