Scientific methods for preparing for pregnancy of girls

Although people's views on gender are no longer as important as before, there are still some families that need a princess, because she can be the warm and caring little cotton-padded jacket of her parents and can accompany her parents to have heart-to-heart talks. So, what are the effective methods for girls in the pregnancy preparation period?

In order to successfully conceive a girl, women need to eat less alkaline foods and more acidic and alkaline foods, but don't eat too much to avoid affecting women's health. This is something that couples need to pay attention to together. The acidity and alkalinity mentioned here do not refer to the strange-smelling foods that our taste buds directly feel, but refers to the pH acidity and alkalinity of the body. Acidic and alkaline foods include meat, fresh milk, freshwater fish, fresh cream, corn, protein, etc.

When women are under great pressure, the probability of getting pregnant with a girl will be higher. When women are overly anxious and stressed, the acidity in their bodies will be greater than alkaline. However, this method is not recommended. If the pressure is too high, it will cause great harm to women's bodies.

When the pH value of the sperm is different, the speed of sperm oscillation is different, and the gender of the fetus will also be different. The probability of X male sperm surviving in an acidic and alkaline environment is relatively high, while the probability of Y male sperm surviving in an alkaline environment is relatively high. When you want to have a daughter, you can choose an acidic and alkaline environment that male sperm likes. Women can use warm water diluted with vinegar to wash the vagina before having sex.

1. Adjust the acidic and alkaline human environment suitable for giving birth to a daughter.

The Y-type sperm that determines the sex of the fetus as a boy is suitable for alkaline living conditions, while the X-type sperm that determines the sex of a girl is suitable for acidic and alkaline living conditions. Therefore, if you want to have a girl, you need to create a space suitable for the survival of the X-type sperm, so as to increase the probability of X-type sperm and egg fusion. Therefore, you should pay attention to the conditioning of acidic physique. Eat more acidic fruits moderately and try to reduce the intake of alkaline foods. In addition, human metabolism is very strong, and changing the body's pH value through food is a long process that requires persistence. You can also try Liu Lao's prescription, which can help us quickly maintain a healthy body.

It should be noted that the criterion for judging whether a food is acidic or alkaline is not whether it tastes sour or not. Do not assume that all fruits that taste sour are acidic. Common acidic fruits mainly include: meat, fish, pasta, corn, exotic fruits, chocolate, vinegar and so on.

In addition, the pH value of the vaginal environment during intercourse is also very important. The X sperm that determines the gender of the fetus moves faster in an acidic and alkaline environment and is relatively active. Therefore, if you want to have a daughter, you can use the characteristics of X sperm in adapting to acidic and alkaline environments and use some methods to change the vaginal environment to make it acidic. Therefore, it is recommended that women can use some vinegar diluted in warm water to wash the vagina before having sex, which will increase the probability of having a girl.

2. Choose the right time to have sex

According to some scientific research results, the amount of sperm in a man during pregnancy affects the chances of having a boy or a girl. More sperm makes it easier to have a boy, while fewer sperm makes it easier to have a girl. Therefore, if you want to have a boy, you need to abstain from sex appropriately, reduce the frequency of sexual intercourse, and allow the man to deposit more sperm. On the other hand, if you want to have a daughter, just have sex as usual and don't abstain from sex.

In addition, we can use the characteristics of X male sperm, which has a long lifespan but slow swing, and Y male sperm, which has a fast movement but a short cycle, to artificially select the golden time for X sperm-egg fusion for intercourse. Having sex before ovulation increases the chances of having a daughter. Therefore, it is very important to learn how to determine the ovulation period. You can choose to test your body temperature, you can also use ovulation test strips to test, you can also go to the hospital to use B-ultrasound follicle monitoring of development status, one cycle is about 5 times, generally hospitals have this project.
