Simple methods to test the most accurate way to look at boys and girls when pregnant with men and women.

A simple way to test pregnant men and women: the formula for testing boys and girls is: your imaginary age when pregnant+pregnancy month+19= odd number of boys and even number of girls.

Nominal Age = (Date of Last Menstruation-Date of Birth) The year in the result is+1.

The above dates are all in the solar calendar.

For example, my birthday was 1980. 12.5, and my last period was 20 10.7.29.

Nominal age calculation:

1, the subtraction result is that the age is 29, July 24th (accurate to the number of days), and the nominal age is 29+1=30.

2. Some friends questioned that my nominal age should be 32 years old. In fact, I am only 29 years and 7 months old, and I am under 30 years old, so my nominal age is 30.

3. Apply formula 30+7+ 19. Even numbers are daughters, but actually they are daughters.

A simple way to test pregnant men and women: look at the gestational sac and you will know that the gestational sac of boys and girls is round and that of girls is round.

Specific analysis:

When I was two months old, I saw an eggplant-like gestational sac, usually a son, and a round or very round gestational sac was a daughter.

A simple way to test whether a boy is pregnant with a girl: by listening to the fetal heart, the location of the fetal heart of a boy and a girl can be detected, and the correct rate can reach 90%. After eight months of pregnancy (at this time, the child will not turn back and forth in the stomach), when listening to the fetal heart, if it is on the left, it is a male treasure and the right is a girl.

A simple way to test pregnant men and women: look at the placenta and know that there are boys and girls.

Before pregnancy, I heard a few friends say that there are more girls in the front wall and more boys in the back wall, and the accuracy rate is about 80%.

Statement 1: If the fetal heart rate is lower than 140 beats/min, the fetus is a boy.

Experts say that the heart rate of girls is higher than that of boys, only at birth, and there is no difference between the fetal heart rate of boys and girls. Heart rate only changes with gestational age. About 5 weeks pregnant, the fetal heart rate is close to the mother's heart rate, that is, 80~85 beats/minute. Then in the ninth week of pregnancy, the heart rate gradually accelerated to 170~200 beats/min. Then it gradually slowed down to 120~ 160 beats/min in the second trimester.

Statement 2: Pregnant women whose abdomen is too prominent are girls, whose abdomen is not too prominent or whose lower abdomen is a boy.

Experts say: if the pregnant woman's upper body is short, the space for fetal development can only extend outward, so the abdomen will appear very large. On the contrary, the height of pregnant women can provide enough space for fetal development, and the abdomen does not need to protrude outward.

Statement 3: A pregnant woman has a boy in her lower abdomen and a girl in her upper abdomen.

Experts say: If a pregnant woman is pregnant, it may be her first pregnancy or she is in good shape. When a pregnant woman is pregnant once, her abdominal muscles relax, and when she is pregnant again, she will naturally "sag".

Statement 4: * * * Black people are boys.

Experts say: the color of * * is influenced by hormones in the body. During pregnancy, the hormone levels of progesterone and melanocytes in the body increase, which causes the originally black part of the body to become darker and will recover quickly after giving birth. This phenomenon has nothing to do with the sex of the fetus.

Statement 5: The relationship between eating acid and alkali and having boys and girls.

Experts say: It is a misunderstanding that some people judge whether food is acidic or alkaline only by taste. It should be emphasized that the state of acid-base imbalance in human body is usually caused by diseases.

Statement 6: Early pregnancy reaction will love to eat hot and sour "sour children and spicy women"

Experts say that there is no scientific basis for the statement that "sour children are spicy women". Medically speaking, the birth of boys and girls is mainly determined by chromosomes. All the eggs in the mother have X chromosomes, while * * * contains X or Y chromosomes. If * * * comes into the egg with X chromosome, it is a girl; If the * * * that enters the egg has a Y chromosome, it is a boy. So it's actually up to the father to decide whether to have a boy or a girl. In a sense, having boys and girls is related to the conception environment of fertilized eggs, that is to say, it is related to the environment around fallopian tubes.

A simple way to test boys and girls: watch boys and girls have sex.

The law of giving birth to boys and girls is open, and personal experience predicts men and women.

1 and * * *

Usually * * * is acidic, and it is alkaline when ovulation day approaches. Considering the nature of X *** and Y ***, it may be possible to achieve a controlling effect to some extent by purposefully choosing * * * days.

Characteristics of 2 days before ovulation date:

(1) The cervical canal does not secrete alkaline mucus.

(2) *** is acidic.

(3)X *** has stronger endurance than Y ***.

(4) The probability of having a girl is higher.

Characteristics of ovulation day:

(1) The cervical canal secretes strongly alkaline mucus.

(2) The alkalinity in * * * increases.

(3)Y *** is better than X ***.

(4) The probability of having a boy is higher.

2. Affected by acid-base environment:

Y *** is alkali-resistant and acid-resistant, Y *** is active in alkaline environment and easy to combine with eggs, and X *** is active in acidic environment and easy to fertilize. Female athletes tend to get girls, which may be caused by the increase of creatinine, creatine and other acidic substances in the blood after strenuous exercise, which is not conducive to Y *** activities. Therefore, some people try to change the pH to control sex.

3, the influence of sexual life:

Reduce the number of sexual intercourse, improve the concentration of * * * and the sensitivity of sexual contact, choose the time of * * * during ovulation, and fully improve the woman's * * *, so that the woman can easily get a boy after having sex. Because of the woman's sexual characteristics, the secretion contains alkalinity. On the other hand, frequent sex and premature sex will increase the chances of having girls.

4, the influence of nutrition:

Pregnant women eat more and are more likely to have boys. A recent study by foreign scientists found that pregnant women who eat a lot during pregnancy usually give birth to a baby boy, and the baby boy born at the same time is heavier than the baby girl.

The researchers observed and studied 244 pregnant women for 6 months. The results show that testosterone secretion from male children's testicles is the direct cause of the large food intake of pregnant women who give birth to boys, which means that pregnant women with large food intake are more likely to give birth to boys.

A simple way to test boys and girls: Tips 1, newborn boys are heavier than girls, which is a common phenomenon and will help to identify the sex of the baby during pregnancy.

2. Pregnant women who give birth to boys consume more than 10% calories and more than 8% protein during pregnancy.

Pregnant women must supplement energy by absorbing a lot of carbohydrates and animal and vegetable fats.

4. The research data also shows that the baby boy in the embryo needs more nutrition and energy than the baby girl.
