Can you know the gender of the fetus by looking at the gestational sac, fetal heart rate, and Tang sieve? Which is true? Which is not reliable?

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, she imagined that the child was playing in it, and she wanted to hold him in her arms and love him immediately. 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, looking at the shape of the gestational sac, the time of showing pregnancy, the shape of the belly, and even some more superstitious ones, using a needle with thread to watch the pulse, etc., can be described as all kinds of strange. Which of these rumors are true? 1. If the gestational sac is round, it is a girl, and if it is long, it is a boy? fake! The shape of the gestational sac is related to many factors. For example: embryo development, bladder enlargement, uterine contractions, uterine fibroids, implantation bleeding, etc., have nothing to do with fetal gender. 2. The method of looking at men and women through Tang screening results is said to be mainly based on the MOM value index of human chorionic gonadotropin (β-hCG) and alpha-fetoprotein (AFP) 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, it is a girl. It sounds scientific, but it's still fake! "Dang screening" refers to the abbreviation of prenatal screening for Down syndrome (Down syndrome, trisomy 21), which is to detect the serum chorionic gonadotropin (β-HCG) of pregnant mothers in the second trimester of pregnancy. , alpha-fetoprotein (AFP) and free estriol (uE3) concentrations, and then based on other conditions of the pregnant mother, such as age, weight, gestational age, etc., to comprehensively calculate the risk of the fetus and baby. 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! Under normal circumstances, pregnant mothers will have a bulging 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. And 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. 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, and the belly will appear pointy, not so mellow. Moreover, the shape of a pregnant mother's belly depends not only on the fetal position, but also on the mother's body shape and the width of the pelvis. 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. In the same way, if the pelvis of the pregnant mother 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 relatively wide and deep, when the fetus grows up, there is still enough space to accommodate him, and the baby can live comfortably without having to find a place. A pregnant mother's belly will look flatter and rounder. 4. The sour girl is 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 body hormones, 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 on the table. 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 that place become a daughter country? 5. Pregnant mothers with alkaline constitution are more likely to give birth to fake boys! 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 fetal heart rate is fast and the fetal movement is mostly boys. This is still fake! The 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 for fetal movement. Many doctors will teach 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. Therefore, these have nothing to do with the gender of the fetus. If the fetal heart rate is too fast, or the fetus moves too much, don't care about the gender, go to the hospital for an examination and protect the safety of the baby!
