TA in the belly, boy? girl?
When you have a big belly, whether it is your relatives, colleagues, friends or classmates, they all start to play guessing games around your belly. But how can we parents guess the gender of a little thing through a layer of belly? ? Who says you can\’t guess? There are many folk ways to identify a baby\’s gender, and they emerge in endlessly. So, how accurate are these methods? Is there any scientific evidence? Let’s analyze them one by one.
Myth 1: Fetal heart rate differs between men and women
There is a legend circulating in the world: It is said that you can tell whether you are pregnant with a boy or a girl by listening to the fetal heartbeat. If the fetus is a girl, the fetal heart rate will be faster; if the fetus is a boy, the fetal heart rate will be slower. There is another argument that is relative to the previous method. It is generally believed that if the fetal heart rate exceeds 140 beats per minute, it is a boy, and if the fetal heart rate is less than 140 beats per minute, it is a girl.
It turns out that girls have a higher heart rate than boys. This is just a condition at birth. There is no difference in the heart rates of male and female fetuses.
Listening to the fetal heart rate requires special equipment. Around 12 weeks of pregnancy, you can use a Doppler stethoscope to listen to the fetal heart rate in a very quiet environment. In the later stages, it is not easy to detect the fetal heart rate with an ordinary stethoscope. The changes in fetal heart rate are related to the number of weeks of pregnancy. At 5 weeks of pregnancy, the fetal heart rate is close to that of the mother, which is 80-85 beats per minute. Then by the 9th week of pregnancy, the heart rate gradually increases to 170-200 beats/min. It gradually slows down to 120-160 beats/min in the second trimester. This has nothing to do with the gender of the fetus.
Rumor 2: The black midline during pregnancy is a boy
There is a legend circulating in the world: After pregnancy, the mother-to-be will have a black line in the middle of her belly, which is called the midline of pregnancy. It is said that the darker the line, the higher the chance of having a boy.
It turns out that the color of the pregnancy midline is affected by hormones in the body. During pregnancy, the levels of progesterone and melanocyte-stimulating hormone in the body increase, which will cause some originally dark parts of the body surface to become darker, which will quickly recover after delivery. This phenomenon has nothing to do with the gender of the fetus.
Rumor 3: Round bellies are girls and pointed bellies are boys
Jianghu Legend: There are many versions of this rumor, both at home and abroad. To sum up, there are several theories: one is that if the belly is rounder than others, it is a girl, and if the belly is pointed than others, it is a boy; the other is that if the belly is bigger at the top, it is a girl, and if the belly is bigger at the bottom, it is a boy.
That’s it: This is a widely circulated statement among the people. Whether the belly is round or pointed has nothing to do with the gender of the fetus. If so, are there any expectant mothers whose bellies are the same size from top to bottom?
Relatively speaking, obese people’s bellies will appear rounder when they are pregnant. On the contrary, if the person is thin, the belly will become pointed. If the pelvis is wide, the fetal head will enter the pelvis, and the abdomen will be low; if the pelvic mouth is small, the fetal head will rise high, and the abdomen will be high. Actually accurateThe shape of the mother\’s belly has a very important relationship with the body shape before pregnancy and whether it is the first pregnancy. If the expectant mother is in very good shape, is pregnant for the first time, and the skin on her abdomen is very tight, then most likely her upper abdomen is too large. And if you have given birth to a child before and your abdominal muscles and skin tissue are somewhat loose, your belly will be bigger during another pregnancy.
Rumor 4: Men and women are judged based on their skin type
There is a legend circulating in the world: If your appearance becomes more beautiful and your skin becomes more delicate after pregnancy, then the child is likely to be a girl. If the spots on your face become more numerous after pregnancy and your complexion is no longer as good as before, then the baby is likely to be a boy.
That’s it: If you have to look for a theoretical basis from a scientific perspective, you may be able to find some clues from an endocrine perspective. If you are pregnant with a girl, and the girl\’s endocrine system is the same as the mother\’s, estrogen secretion is dominant, then the mother\’s endocrine system will output more, or it will be equivalent to the mother taking estrogen, and the skin will naturally improve and become more beautiful. Mature. Better come. If you are pregnant with a boy, the boy\’s endocrine system will secrete male hormones. Just imagine what would happen if a woman took male hormones. The pores would become larger and the skin would become thicker. The results might be ugly. However, there are no relevant research results to prove this.
Rumor 5: Fetal movement patterns are divided into men and women
There is a legend circulating in the world: if the left belly moves, it means a boy, and if the right belly moves, it means a girl. Another saying is that girls\’ fetal movements are softer and are like a point, while boys\’ fetal movements are like a line, which are always frequent and non-stop.
It turns out that this is the case: It turns out that the relationship between men on the left and women on the right begins with fetal movements. So if both parties move together, are they sure they are having twins? It is suitable for many occasions when men are on the left and women are on the right. It is a matter of habit, but it is not suitable for fetal movements. Changes in fetal position can occur in a variety of ways. For example, the fetus may change position or move because the mother is uncomfortable sitting or standing. It is also possible that the mother is exercising due to her emotional reaction. When the mother is angry, happy, excited, nervous, anxious or fearful, the body will release some special hormones, such as adrenaline, etc. These chemicals can pass through the blood and enter the placenta into the blood of the fetus, and the fetus will respond to the mother\’s mood. Variety. These will cause changes in fetal position. This happens to many expectant mothers. The last fetal movement was on the left, this time it was on the right. This is not a change in the sex of the fetus, just a change in the position of the fetus.
Myth 6: The location of the placenta
There is a legend circulating in the world: If the placenta is on the back wall of the uterus, you will have more boys; if the placenta is on the back wall of the uterus, you will have more boys. If the placenta is on the front wall of the uterus, most babies are girls.
So it turns out: this statement comes more from experience. There is currently no scientific evidence to prove this. If the placenta is neither on the front wall nor on the back wall, but grows on the side wall, is it a boy?Where is the girl?
Rumor 7: A long gestational sac is a boy, and a round gestational sac is a girl
Jianghu legend: Some people say that men and women can also be identified by looking at the data from B-ultrasound films. In boys, the gestational sac is elongated before two months of pregnancy, while in girls, the gestational sac is oval or round.
That’s it: An expectant mother’s gestational sac looks different in shape, regardless of the gender of her baby. Generally, a well-developed gestational sac is round and flat, but sometimes the gestational sac can become elongated according to the shape of the uterine cavity. The shape of the gestational sac is determined by the tension of the uterus and the amount of amniotic fluid, and it will change shape on its own. In this way, depending on the number of days of pregnancy, the gestational sac seen may also be different. In addition, the direction of the B-ultrasound probe is different every time, and the shape of the gestational sac is also different when viewed from different angles.
Same.
Rumor 8: Dreaming hints at the gender of the baby
Legends of the world: Many people say that dreaming about dragons, tigers, snakes, turtles, chestnuts, etc. indicates that it is a boy; dreaming about red peppers and fruits , flowers, butterflies, etc. indicate that it is a girl.
That’s it: In fact, as the saying goes, “Think about it every day and dream about it at night,” fetal dreams are no exception. As for whether you have a boy or a girl in your belly, it has nothing to do with the dream. It\’s just your consciousness that is causing trouble.
