Life has a kind of saying that the acidity of food can change the body's pH value, thus affecting the female vaginal secretion of substances, if the secretion of alkaline substances, it is suitable for the survival of Y spermatozoa, and therefore more prone to have a boy, on the contrary, if the secretion of acidic substances, acidic environment is more suitable for the survival of X spermatozoa, prone to have a girl. Alkaline foods are mostly vegetables and fruits, such as potatoes, spinach, tomatoes, cabbage, carrots, apples, bananas, papayas, sorbets and oranges.

The claim that eating more alkaline food can give birth to a boy is not accurate from a medical point of view. Because the body's PH value is basically constant, it is difficult to change the body's PH value just by a certain type of food. In addition, pregnant women need more nutrition, if only consume alkaline food but not eat acidic food, such as pork, chicken, fish and other meat food, a single diet is likely to lead to malnutrition. Therefore, pregnant mothers should still pay attention to both acidic and alkaline foods in moderation.

Alkaline water rinse vagina

Some couples want to have a boy, you can consider how to enhance the alkaline environment of the vagina, so as to allow Y sperm to survive longer, in addition to the said change of food, you can use alkaline water to rinse the female vagina. If you want to have a boy, enhance the alkaline environment of the vagina.

In fact, the use of alkaline water to douche the vagina, this practice is not scientific, and, because the vagina is very susceptible to infection, if the use of liquids such as soda to douche the vagina, but may lead to an imbalance in the vaginal flora induced inflammation, so all the mothers preparing to conceive to improve the chances of having a boy in the use of this method, especially to be careful when considering.

Making an orgasm

Normal women's vaginas are usually strongly acidic, and after the first orgasm, it will change to acidic, and after the second orgasm, it will change to weakly acidic. The semen is alkaline, and when a woman reaches orgasm, it will enhance the alkalinity of the vagina, which is more suitable for the growth of sperm with Y chromosome. Therefore, if you want to give birth to a boy, you should try to create an orgasm, and increase the chances of making the vagina alkaline and strong.

It is one of the prerequisites for men and women to be able to conceive, to ejaculate and combine with the egg to form a fertilized egg during intercourse so that they can conceive successfully. Creating an orgasm during intercourse is a wonderful experience for both men and women, and at the same time, a woman's orgasm makes it easier to promote the combination of sperm and egg. However, it still requires effort from both parties to make the Y sperm break through the breakout and fertilize the egg.

Conception in summer

The ambient temperature of the month before the fertilization of the egg, that is, the temperature of the environment in which the boy and the girl are living in the month before the sexual intercourse takes place, is one of the important factors affecting the sex of the baby. If you want to have a boy, it is best to conceive in summer, and similarly, if you want to have a girl, try to conceive in winter. This is because high temperatures tend to create male babies and low temperatures tend to create female babies. High temperatures affect the X chromosome of sperm, making female babies less likely to be born; low temperatures affect the Y chromosome of sperm, making male babies less likely to be born.

There is not enough scientific evidence on whether the environmental temperature at the time of conception can affect the sex chromosomes and thus the sex of the baby, regardless of the season of conception, it is the male sperm that determines the sex of the baby. It is important to note that in the summer, you should avoid blowing directly into the air conditioner or fan, and in the winter, you should pay attention to the warmth to avoid getting cold, so as to regulate the body, so that the baby can develop healthily.

Choose a standing or backward position

Wanting to have a boy, you can take a standing or backward position, and lie down quietly for a while after intercourse. This kind of coitus position is able to make the penis deeper, easier to ejaculate, ejaculation position deep, sperm can reach the uterus earlier. So, if you want to have a boy, ejaculate deep into the vagina during intercourse, which will help the Y sperm to emerge near the cervix and reduce its difficulty in traveling long distances through the cervical mucus. Similarly, if you want to have a girl, try the missionary position or woman-on-top coitus position.

Not too late to have children

A man's sperm count decreases with age, so older men have a higher chance of having a girl. Similarly, the older a woman gets, the more the alkaline secretions in the uterus decrease year by year due to the effects of aging, and the chances of having a girl increase dramatically. Therefore, older couples have a higher chance of having daughters than younger couples.

This is not necessarily accurate. Because having a boy or a girl is just a matter of probability, it doesn't have much to do with age. However, from the perspective of eugenics, couples should conceive their babies at the optimal reproductive age. Women's reproductive age between 23-30 years old is the best period, men are 30-35 years old, women are best not more than 30 years old, men are not more than 35 years old.
