The theory of sex determination holds that a boy will be born only when male Y sperm fertilizes a female egg. In recent years, more scientific research has proven that the Y chromosome is more likely to survive and be more active when the female vagina is alkaline, so it is more likely to combine with the egg. It is said that washing the vagina with soda water can make the female vagina alkaline. So, is it scientific to use soda water to conceive a boy? Is it scientific to wash the vagina with soda water to give birth to a boy?

The folk remedy of washing the vagina with soda water is easy to give birth to a son. Many couples who want to have a boy are overjoyed. Before getting married, women can use 2-2.5% soda water to rinse the vagina, so that the vagina will be in an alkaline environment. According to the saying "Alkaline body constitution is more likely to give birth to a boy, and acidic body constitution is more likely to give birth to a girl", using this method to prepare for pregnancy can increase the chance of giving birth to a boy. In fact, in comparison, this acid-base constitution is quite convincing, but in reality it is not so full.

In fact, it is indeed a bit alarmist to say that washing the vagina with soda water can lead to a boy, and it has no scientific basis. Experts point out that the human body's pH value is often a constant value, and huge deviations cannot occur by washing alkaline or acidic liquids or eating certain types of food. Soda water is indeed an alkaline drink, but the medical community has not yet reached a conclusion on the impact of human body pH on health. Therefore, there is no scientific basis for using soda water to clean the lower body to conceive a boy. Since there is no scientific preparation for pregnancy, a natural mentality is more suitable for pregnancy. Pregnant women should not care too much about the gender of men and women, and they will be much more relaxed and happy.

Experts do not recommend that women wash their vaginas with soda water to prepare for pregnancy, as this is not good for their health. In clinical practice, I have come across many women who used baking soda water to flush their vaginas to give birth to sons, but the results were unsatisfactory. As we all know, women’s vaginal environment is acidic, while soda water is alkaline. Washing the vagina with soda water will cause an imbalance of vaginal flora and reduce the anti-bacterial ability of women’s private parts. Tips for conceiving a boy or a girl

1. Choose the time of intercourse: If you want to conceive a boy, you can have intercourse (or insemination) during the ovulation period, that is, it is easier to conceive a boy, because sperm Y is more fragile and cannot wait as long as sperm X, and The closer the ovulation period is, the thinner and alkaline the cervical mucus becomes, which is beneficial to sperm Y. On the contrary, if you want to conceive a girl, the farther away from the ovulation period is, the better. At this time, the cervical mucus will be thicker and more acidic, which is not good for sperm Y and relatively resistant to sperm X.

2. Master the orgasm: During sexual intercourse, pay attention to regulating the orgasm. Some people say: "Because your wife had an orgasm, she gave birth to a boy." This is well-founded. Because the vagina is acidic, when a woman reaches orgasm, the mucus secreted by the cervix is ??alkaline. In other words, the higher the orgasm a woman feels, the more alkaline secretions there are, and the easier it is for Y sperm to survive. On the contrary, if the man ejaculates before the woman reaches orgasm, some Y sperm will lose their vitality due to the contact of the semen with the acidic secretions in the vagina, which may increase the chance of a female fetus.

3. Control the frequency of sexual life: 18-25 years old, 10-30 times a month; 25-35 years old, 5-15 times a month; 35-45 years old, 2-10 times a month. Normal people produce 30 million sperm every day. Frequent sexual intercourse can reduce the number of sperm, resulting in a low proportion of sperm Y. Extending the interval between sexual intercourse can increase the number of sperm, resulting in a high proportion of sperm Y. Therefore, those who want to have a boy should have a longer interval between sexual intercourse. To improve the quality and concentration of semen. If you want to have a girl, there is no need to limit the interval between sexual intercourse.
