Scientific Methods for boys or girls

Preparation:
1. Fill in the basic thermometer correctly every day to help determine the ovulation day. If it is not determined, go to the hospital to check the cervical mucus;
2. Use condoms for contraception within two to three months before the date of failure to determine ovulation;
3. Preferably two days before the ovulation day **;
4. You need to adopt the ** posture (I .e. ** cannot be inserted too deep) that is conducive to the birth of girls );
5. ** stop sex for a week.
Principles:
1. Stop sex three days before ovulation
On the day of ovulation, women usually have a large amount of transparent mucus, which can prevent sperm from entering the uterus and staying only in the acidic zone, in an acidic environment, it is not suitable for Y sperm growth, so that Y sperm is eliminated, and X sperm is left behind. After the mucus in the uterus is dissolved, X sperm can be smoothly combined with the eggs, the birth of a baby girl. Because sperm has a three-day survival period in the uterus, if you want to avoid Fertilization on the day of ovulation, you must stop the row three days before the ovulation day.

2. Make ** Acid
X and Y sperm swim at different speeds in different environments with different acid and alkali values. Y sperm swim in an alkaline environment, while X sperm is more active in an acidic environment. Therefore, if the couple want to give birth to a girl, they can use X sperm to prefer the acidic properties and set the ** environment to acidic, so that they can raise the possibility of giving birth to a daughter. Before sex, the woman can also dilute acetic acid with a small amount of clean warm boiled water and rinse the women ** to make ** an acidic environment and help the child.
3. When the woman is in the house, try to avoid climax
Normal female ** usually shows strong acidity (ph3.8 ~ 4.2), the first climax is acidic (pH5.2 ~ 6.0), the second climax will become weak acid (pH6.3 ~ 6.8 ). Because ** is alkaline (pH7.4 ~ 7.8), and when it reaches the climax, it will enhance ** alkaline, coupled with alkaline environment is more suitable for Y sperm growth, so if you want to give birth to a daughter should try to avoid climax, reduce the chance of ** alkaline enhancement.

4. Frequent sexual activities
Couples who want to give birth to their daughter do not have to limit the number of sexual activities before the last trip. The higher the number of sexual behaviors, the less Y sperm can be used. However, although the number of sexual behaviors does not have to be controlled, it cannot be excessive to avoid excessive physical exertion.

5. Position
If you want to give birth to a daughter, you can try to adopt a shallow insertion posture during sexual behavior. The male adopts the shallow insertion position, and the injected sperm must stay in the acidic ** for a period of time, so that the Y sperm can be eliminated as much as possible, leaving only X sperm.

6. Adjust the Constitution from the diet
Couples who want to have a baby girl can try to increase the acidity in the woman's blood, which can also increase the acidity of **, which is conducive to the birth of a baby girl. Therefore, the woman can try to eat fish, meat, protein and sour fruit to make the Constitution acidic; while the gentleman can eat more alkaline food.

Acidic food: Loach, ham, beef, pork, chicken, and fish (Sea catfish, catfish, mackerel, salmon, mackerel, etc) wood fish, protein, acid fruit (tomato, orange, strawberry, grape, apple, pineapple, etc ).
Alkaline food: vegetables, fruits, milk, flour products, tea, kelp, seaweed, iodine, calcium, vitamin D.
After paying attention to all the above problems, the chance of giving birth to a girl will be greatly improved.

How to give birth to a boy

Preparation:
1. Before preparing for pregnancy, correctly measure the basal temperature. The day of sudden decline is the ovulation day. If you are not sure, you can go to the hospital to check the cervical mucus to help determine;
2. On the day of ovulation or the next day **, because ** the secretion is alkaline at this time, it is conducive to the survival of Y sperm;
3. Take natural calcium (4 capsules) every day until the doctor confirms that you are pregnant;
4. Use of condom contraception within two months before pregnancy. Other methods of contraception are not allowed;
5. Adopt the positions that are conducive to the birth of boys **;
6. ** the higher the intensity, the better. Therefore, you should be patient before preparation.
Principles:
In this way, a large number of dynamic sperm can be quickly fed into the ** body. ** after the insertion, women do not move their bodies first, you can clamp your legs and raise your hips for 20 minutes.
The alkaline environment is conducive to the survival of Y sperm and thus to the birth of boys. This alkaline liquid is most secreted during orgasm. As for how to reach the climax, it depends on the cooperation between husband and wife.
If the above points are met, the chance of giving birth to a boy will be greatly improved.
Dietary focus:
If you want to give birth to a boy, female eats alkaline food and male eats acidic food.
Alkaline foods include vegetables, fruits, milk, flour products, tea, kelp, seaweed, iodine, calcium, and vitamin D;
Acidic food: beef, chicken, fish, protein, sour fruit.
