It is best to have sex two days before the day of ovulation; 4.
Need to adopt sexual positions that are conducive to the birth of girls (that is, the penis should not be inserted too deep); 5.
After sex, stop having sex for a week.
原则： 一、在排卵日前三天停止性行为 通常在排卵日当天，妇女的体内就会分泌多量且透明的粘液，这些粘液可以阻止精子进入子宫中，只停留在酸性的阴道里，在酸性的The environment is not suitable for the growth of Y sperm, so that Y sperm is eliminated, and X sperm is left. After the mucus of the uterus is dissolved, the X sperm can smoothly combine with the egg and give birth to a baby girl.
Because sperm have a three-day survival period in the womb, if you want to avoid fertilization on the day of ovulation, you must stop making sex 3 days before ovulation.
Second, make the vagina appear acidic. X and Y sperm swim differently in different pH environments; Y sperm swim more in alkaline environments, while X sperm are more active in acidic environments.
Therefore, if the couple hopes to have a girl, they can use X sperm to like the acidic traits and arrange the vaginal environment to be acidic, which can increase the possibility of having a daughter.
The woman can also dilute the woman’s vagina with a small amount of clean warm water before sexual intercourse, so that the vagina presents an acidic environment, which helps to have a girl.
3. When the woman is in the room, try to avoid orgasms. The vagina of normal women usually shows strong acidity (ph3.
2), acidic after the first orgasm (ph5.
0), after the second orgasm, it will change to weakly acidic (ph6.
Because semen is alkaline (ph7.
8) When reaching orgasm, the vaginal alkalinity will be enhanced, and the alkaline environment is more suitable for the growth of Y sperm, so if you want to have a daughter, you should try to avoid orgasm and reduce the chance of increasing vaginal alkalinity.
Fourth, the number of sexual acts should be frequent contemplation of the couple giving birth to the daughter, before the last sex, there is no need to restrain the number of sexual acts.
Because the more the number of sexual acts, the number of Y sperm can be reduced, but although the number of sexual acts does not need to be restrained, it must not be excessive, so as not to consume excessive physical strength.
Fifth, the couple who wants to have a daughter can take a shallow insertion position during sex.
The man takes a shallow insertion position, and the sperm ejected must stay in the acidic vagina for a period of time, so that the Y sperm is eliminated as much as possible, leaving only the X sperm.
Six, couples who want to have a baby girl from their diet can try to increase the acidity of the woman’s blood, which can also increase the acidity of the vagina, which is conducive to the birth of a baby girl.
Therefore, the woman can try to eat fish, meat, protein, and sour fruits to make the body more acidic; while the husband can eat more alkaline food.
Acidic food: loach, ham, beef, pork, chicken, fish (sea mullet, catfish, bream, salmon, salmon, mackerel, bonito, catfish, etc.) wood fish, egg white, sour fruits (tomato, orange, Strawberry, grape, apple, pineapple, etc.).
Alkaline foods: vegetables, fruits, milk, flour products, tea, kelp, seaweed, iodine, calcium, vitamin D.
After paying attention to all the above questions, the chance of having a girl will be greatly improved.
