Does the posterior wall of the placenta always result in a girl?

There are many ways in folk customs to distinguish the gender of a baby, such as observing the size of the pregnant woman's abdomen, observing the changes in the pregnant woman's skin, observing the pregnant woman's diet, etc. Some also calculate by looking at the face. The more scientific way to distinguish the difference between a boy and a girl is to check the placenta to see if you are pregnant with a boy or a girl.

Generally, the sex of the fetus can be determined by B-ultrasound around April, but it depends on the position of the fetus. When the fetal position is beautiful, it is accurate, but don't be too confident in the judgment. For determining the sex of the fetus, the most intuitive way is B-ultrasound. Under B-ultrasound, you can clearly see every organ and position of the fetus, including the sexual organs. However, our Chinese law currently stipulates that it is not allowed to privately inform the pregnant woman of the sex of the fetus. It is a violation of the law. Another way is amniocentesis to test the sex chromosomes.

In tissue cells, there are 23 pairs of sex chromosomes (human genetic information), of which only one pair is chromosomes, which determines the gender of the fetus. These two chromosomes, one comes from the mother and one comes from the father. If both are X-shaped, a girl will be born in the future; if one is X-shaped and one is Y-shaped, a boy will be born.

The female ovaries produce several eggs every month, but usually only one perfect egg is released. They all contain only X-type chromosomes. In other words, the sex of the fetus is not determined by the mother.

The speed of the fetal heartbeat can be used to determine whether it is a boy or a girl. It is generally believed that if the fetal heartbeat is strong and fast, the possibility of having a boy is very high; otherwise, the possibility of having a girl (one of the more common symptom methods of guessing a boy or a girl) is higher.

How to distinguish between boys and girls

Differentiation method 1: Judging from the shape of the pregnant woman's abdomen. If a pregnant woman's belly is pointed, she will be pregnant with a boy; if the belly is plump, she will be pregnant with a girl.

Difference method 2: Look at the changes in the pregnant woman's skin and appearance. If the pregnant woman's face becomes more beautiful and her skin becomes smoother, she may be pregnant with a girl; on the contrary, if her face becomes uglier, her skin becomes rougher, or even her face is covered with acne and other symptoms, she may be pregnant with a boy. This is a more common way to conceive a boy or a girl.

Differentiation method 3: Determine whether the pregnant woman is having a boy or a girl by the change in her taste. Some people think that if the taste of a pregnant woman is different from that of the previous pregnancy, the chance of having a boy or girl will also change. If the taste is the same as before, then the gender is also the same, otherwise it is the other way around. Difference 4: Expectant mothers who are pregnant with boys like to eat their favorite foods. The average protein intake of pregnant women carrying a boy is 8% higher than that of pregnant women carrying a girl, the carbohydrate intake is 9% higher, the animal fat intake is 11% higher, and the vegetable fat intake is 15% higher. Pregnant women who were pregnant with a boy ate much more food during pregnancy than when they were not pregnant, but they did not show symptoms of eating different or strange foods, but just ate the foods they usually liked.
