Five secrets to control the gender of the baby

To know the sexual intercourse techniques for giving birth to a boy or a girl, you must first understand the principles of human gender formation. This is the theoretical basis of all sexual intercourse techniques.

Normal women release one egg in one menstrual cycle, and the sex chromosomes of the eggs are all the same, which are all X chromosomes. There are two types of sex chromosomes in sperm: one is sperm with X chromosome (commonly known as X chromosome sperm or X sperm); the other is sperm with Y chromosome (commonly known as Y chromosome sperm or Y sperm).

If the sperm that enters the egg is an X chromosome sperm, the fertilized egg formed by the combination with it will have XX sex chromosomes, that is, a female fetus; if the sperm that enters the egg is a Y chromosome sperm, the fertilized egg formed by the combination with it will have XY sex chromosomes, that is, a male fetus will be formed. Therefore, the sex of the fetus is completely determined by the male's sperm. During sexual intercourse, among the hundreds of millions of sperms ejaculated into the vagina at one time, the number of Y sperms is extremely dominant, twice that of X sperms. However, in the end, the number of Y sperms is almost the same as or even less than that of X sperms.

X sperm and Y sperm are different in appearance and properties. X sperm is the sperm that determines the birth of a baby girl. Its characteristics are: the sperm head is larger, oval-shaped, and the tail is shorter, so it is heavier and moves slower, but it has stronger acid resistance and relatively stronger vitality. It survives longer and can survive in the uterine cavity or fallopian tube for 2-3 days after entering the vagina.

Y sperm is the sperm that determines the birth of a boy. Its characteristics are: the sperm head is small, round and slightly pointed (pointed head), the tail is long, the swimming speed is fast, the acid resistance is weak, it is easily frustrated, the survival time is short, and it will die soon. After entering the vagina, it can only survive in the uterine cavity and fallopian tube for 24 hours.

Sexual intercourse secrets to determine whether you will have a boy or a girl: Sexual intercourse temperature

German researchers tracked birth records between 1946 and 1995 and compared them with local temperature changes. The results showed that April to June were the months with the most baby boys born, while October was the month with the least baby boys born.

Further analysis shows that the environmental temperature one month before the fertilized egg is combined, that is, the temperature of the environment in which the boy and the girl are in one month before sexual intercourse, is an important factor affecting the baby's gender. A high temperature environment is more likely to create a baby boy, while a low temperature environment is more likely to create a baby girl.

The reason why temperature affects the baby's gender is that the researchers' hypothesis is that high temperature will affect the X chromosome of sperm, making it difficult for a female baby to be born; low temperature will affect the Y chromosome of sperm, making it difficult for a male baby to be born.

Secret to controlling the gender of the baby 2: Find the right time

The vagina is usually acidic, but becomes alkaline near the day of ovulation. Considering the properties of X sperm and Y sperm, deliberately choosing the day of intercourse may achieve the effect of controlling gender to some extent. Abstaining from sex (for about 5 days) until the day of ovulation can increase the chances of having a boy.

Characteristics of the 2 days before ovulation

1. The cervical canal has not yet secreted alkaline mucus.

2. The vagina is acidic.

3. X sperm has stronger endurance than Y sperm.

4. The probability of having a girl is higher.

Characteristics of ovulation day:

1. The cervical canal secretes strong alkaline mucus

2. The alkalinity in the vagina increases.

3. Y sperm is more powerful than X sperm.

4. The probability of having a boy is higher.

Secret to controlling the gender of the baby 3: changing the acid and alkali

Sperm with X and Y chromosomes swim at different speeds in different pH environments: sperm with Y chromosomes are more active in alkaline environments, while sperm with X chromosomes are more active in acidic environments. Therefore, if the couple hopes to have a girl, they can dilute acetic acid with a small amount of clean warm water and then rinse the woman's vagina to make the vagina acidic. Otherwise, a boy will be born.

Secret of sex to control the gender of the baby 4: Create orgasm

The vagina of a normal woman is usually highly acidic. After the first orgasm, it will become acidic, and after the second orgasm, it will become weakly acidic. Semen is alkaline in nature. When a woman reaches orgasm, the alkalinity of the vagina will be enhanced, making it more suitable for the growth of sperm carrying the Y chromosome. Therefore, those who want to have a boy should try their best to create an orgasm to increase the chance of making the vagina more alkaline.

Secret to sex to control the gender of the baby 5: Choose the right sex position

Normal position - the wife lies flat on her back with her legs apart and bent, and the husband ejaculates when his wife climaxes.

Bent position - the wife's legs are bent and raised, and the husband ejaculates deep inside his wife's vagina.

Doggy style position - the wife lies on her stomach with her knees touching the ground and her legs spread apart, while the husband ejaculates close to her waist.

Front seat position - the husband lies flat with his legs stretched out, and lets his wife sit on top. The husband ejaculates when his wife reaches orgasm.

Side-lying position - the wife lies flat on her back with her legs open, and the husband and wife's bodies are close. In this position, the male's penetration is very shallow, and it is less likely for the woman to reach orgasm. The sperm takes a longer time to reach the uterus, and most of the Y sperm are eliminated early.

Stretched position - when the wife's legs are stretched out and she has not reached orgasm, the husband inserts immediately before ejaculation.

Cowgirl position: The wife lies on her stomach with her legs spread apart, and the husband penetrates her from behind and ejaculates before she reaches orgasm.

Rear position - the wife lies on her side and the husband lies on the back. It is less likely for women to reach orgasm in this position.
