After the pregnant mother’s belly gradually grows, she feels the fetus moving inside, and she must have a smile at the corner of her mouth, while stroking her belly, while imagining the child playing in it, she can’t wait to immediately Take him in your arms and love him.
When chatting with others, the topic will automatically shift to the child in the womb, especially about the gender of the child, everyone will share some of their own experiences.
For example, look at the shape of the gestational sac, look at the time of pregnancy, look at the shape of the belly, and even some more superstitious ones, such as hanging from a needle wearing thread to see the pulse, etc. It’s weird.
Which of these rumors is reliable?
1. The round gestational sac is a girl, and the long strip is a boy?
Fake!
The shape of the gestational sac depends on many factors. For example: embryo development, bladder enlargement, uterine contractions, uterine fibroids, implantation bleeding, etc., have nothing to do with fetal gender.
2. See men and women through the Tang sieve results
This method is said to be mainly based on the MOM value index of human chorionic gonadotropin (β-hCG) and alpha-fetoprotein (AFP) reported on the Tang screening report of pregnant mothers.
It is rumored that when hCG is between 0.5 and 1, AFP is greater than 1, it is a boy, otherwise it is a girl; when AFP is greater than 1, and hCG is less than 0.5, it is a boy, and vice versa girl.
Sounds like science, but it’s still fake!
“Tang screening” refers to the abbreviation of prenatal screening for Down syndrome (Down syndrome, trisomy 21), which is used to detect serum levels of pregnant mothers in the second trimester of pregnancy. The concentrations of chorionic gonadotropin (β-HCG), alpha-fetoprotein (AFP) and free estriol (uE3), and then based on other conditions of the pregnant mother, such as age, weight, gestational age, etc., comprehensively calculate the fetal baby risk of disease.
Therefore, this test does not involve the detection of the sex of the fetus, and there will be no different test results due to differences in the sex of the fetus.
The “test value / reference standard value” circulating on the Internet can determine the gender of the fetus, which has no scientific basis at all.
3. A boy with a pointed belly and a girl with a round belly?
Fake!
Usually, expectant mothers have a round belly. Because the normal fetal position is the front of the pillow, the baby’s back and back of the head will be close to the mother’s belly, just like when we sleep on our side. The pregnant mother’s belly will be round like a bow.
Some babies are naughty and don’t like to lie down in this position, but prefer to change the pose. That becomes a back-pillow position, in which the little one puts his little face, chest and tummy close to his mother’s belly.
And when the baby moves, their little hands and feet will arch to and fro, and because of the fetal position, their range of motion is on the side of the pregnant mother’s belly, The belly will appear pointy and not so round.
In addition, the shape of a pregnant mother’s belly depends not only on the fetal position, but also on the mother’s body shape and pelvis width.
The thinner the pregnant mother, the sharper the belly will appear. Because the thinner the mother is, the narrower the space in the belly will be. If the baby can’t expand his body, he will squeeze forward, and the belly will look pointy.
Similarly, if the pregnant mother’s pelvis is relatively narrow and shallow, then as the baby grows, the pelvis will gradually be unable to accommodate the fetus, and it will be pushed forward and the belly will be pointed. .
And if the pregnant mother’s pelvis is wider and deeper, when the baby grows up, there is still enough space for him, and the baby can live comfortably without having to find a place. A pregnant mother’s belly will look flatter and rounder.
4. Sour girl
Fake!
This statement is really widely circulated. Although some people refute the rumor every year, there are always many people who believe it.
Many pregnant mothers will be affected by hormones in their bodies, the activity of digestive enzymes will be reduced, their appetite will be poor, and they will not want to eat anything.
At this time, hot and sour foods can stimulate the appetite of pregnant mothers, stimulate gastrointestinal motility, help digestion, and become essential food for many expectant mothers.
But this has nothing to do with the sex of the fetus. In some places, such as Sichuan, Jiangxi, and Hubei, almost every meal has chili peppers. If this statement is true, wouldn’t it be the case there? daughter country?
5. Pregnant mothers with alkaline constitution are more likely to have boys
Fake!
The so-called acid-base constitution is a pseudo-theory. Its founder, Robert Ouyang, admitted on the spot that he was not an expert and had not done any scientific experiments in an accusation of illegal medical practice.
In fact, the human body itself is weakly alkaline, and the normal pH value in the body is mainly between 7.35-7.45. Even if you eat more “acidic food” or “alkaline food”, it is difficult to change the PH value of the human body. Not to mention that it will also affect the sex of the fetus.
6. The fetal heart rate is fast and the fetal movement is mostly boys
Many people think that boys are more lively and active, so the ones with fast fetal heart rate and more fetal movements must be boys.
This is still fake!
Fetal heart rate and fetal movement are the most intuitive reflections of the safety of the baby in the mother’s womb. The fetal heart rate is like an adult’s heart rate, with a fixed range. The normal fetal heart rate is between 110 and 170 per minute.
The same is true of fetal movement. Many doctors will ask pregnant mothers to monitor fetal movement, or go to the hospital for monitoring at a fixed time. If the child has intrauterine distress, asphyxia, hypoxia, etc., the fetal movement will be abnormal.
So, these have nothing to do with the gender of the fetus. If the fetal heart rate is too fast, or the fetal movement is too much, don’t care about the gender, go to the hospital for examination and protect the safety of the baby!
