There is a saying in life that the pH of food can change the pH of human body, thus affecting women's vaginal secretions. If alkaline substances are secreted, it is suitable for Y sperm to survive, so it is easier to have boys. On the contrary, if acidic substances are secreted, the acidic environment is more suitable for X sperm to survive and it is easy to have girls. Alkaline foods are mostly vegetables and fruits, such as potatoes, spinach, tomatoes, cabbage, carrots, apples, bananas, papaya, Sydney, oranges and so on.
Eating more alkaline food can give birth to boys, which is not accurate from a medical point of view. Because the PH value of human body is basically constant, it is difficult to change the PH value of human body only by a certain food. In addition, pregnant women need more nutrition. If they only eat alkaline food instead of acidic food, such as pork, chicken and fish, a single diet can easily lead to malnutrition. Therefore, pregnant mothers should pay attention to eating both acidic and alkaline foods in moderation.
2, alkaline water rinse vagina
Some couples want to have boys, so they can consider how to enhance the alkaline environment of vagina and make Y sperm live longer. Besides changing food, they can also clean women's vaginas with alkaline water. If you want to have a boy, enhance the alkaline environment of the vagina.
In fact, it is unscientific to wash the vagina with alkaline water, and because the vagina is very susceptible to infection, washing the vagina with soda water and other liquids may lead to imbalance and inflammation of vaginal flora, so pregnant mothers should be especially careful when using this method to improve the chances of giving birth to boys.
Step 3 create an orgasm
Normal women's vaginas are usually strongly acidic, which will become acidic after the first orgasm and weakly acidic after the second orgasm. Semen is alkaline, which will enhance the alkalinity of vagina when women reach orgasm, and is more suitable for the growth of sperm with Y chromosome. Therefore, pregnant parents who want to have a boy should try their best to create an orgasm and increase the chance of making the vagina alkaline.
Sharing a room is one of the prerequisites for men and women to conceive. When you are in the same room, you can ejaculate smoothly and combine with the egg to form a fertilized egg, thus getting pregnant smoothly. Reaching orgasm in the same room is a wonderful experience for both men and women. At the same time, when women reach orgasm, it is easier to promote the combination of sperm and eggs. However, whether Y sperm can successfully break through fertilization still needs the efforts of both sides.
4, pregnant in summer
The environmental temperature one month before fertilized eggs are combined, that is, the environmental temperature of boys and girls one month before having sex, is one of the important factors affecting the sex of babies. If you want to have a boy, you'd better conceive in summer. Similarly, if you want to have a girl, you should try to conceive in winter. This is because high temperature environment is easy to make a boy baby, and low temperature environment is easy to make a girl baby. High temperature will affect the X chromosome of sperm, making it difficult for baby girls to be born; Low temperature will affect the Y chromosome of sperm, making it difficult for a baby boy to be born.
At present, there is not enough scientific basis whether the environmental temperature can affect the sex chromosome and thus the sex of the baby at the time of conception. No matter what season the baby is conceived, it is the male sperm that determines the baby's sex. It should be noted that after sharing a room in summer, you should avoid blowing directly at the air conditioner or fan. Pay attention to keep warm in winter, avoid catching a cold, recuperate the body and let the baby develop healthily.
5, roommate posture choose standing posture or leaning posture.
If you want to have a boy, you can stand or lean back and lie flat quietly for a while after the same room. This same-room posture can make the penis deeper and ejaculate more easily. The position of ejaculation is deeper, and sperm can reach the uterus earlier. Therefore, if you want to have a boy, inject semen deep into the vagina during sexual intercourse, which will help Y sperm appear near the cervix and reduce the difficulty of its long journey through cervical mucus. Similarly, if you want to have a girl, try missionary position or female bed position.
6、? The childbearing age should not be too late.
The sperm count of men will decrease with age, so the chances of older men giving birth to girls are particularly high. Similarly, the older a woman is, due to the influence of age, the alkaline secretion in the uterus will decrease year by year, and the chance of giving birth to a girl will greatly increase. Therefore, older couples are more likely to have daughters than younger couples.
In fact, this statement is not necessarily accurate. Because having boys and girls is only a matter of probability, and it has nothing to do with age. But from the perspective of eugenics, couples should have children at the best reproductive age. The best childbearing age for women is 23-30 years old, for men it is 30-35 years old, and it is best for women not to exceed 30 years old, and for men it is best not to exceed 35 years old.
