Low fetal position is usually a boy or a girl. Some people say that a low fetal position is a boy and a high fetal position is a girl. If the pregnant woman's face is fleshy and round and full, she will have a girl; If a pregnant woman's right breast is bigger than her left breast, it will be a boy. If the prospective father gains weight, it must be a boy. The sex of the baby is determined by the sperm when the fertilized egg is formed, and has nothing to do with the position of the placenta. After 4-5 months of pregnancy, you can pass the examination of B-ultrasound and judge the sex according to the situation of external genitalia.
Prenatal fetal posture in the uterus is very important, which is related to whether pregnant women are in labor or dystocia. We know that the fetus in the womb is soaked in amniotic fluid. Because the head of the fetus is heavier than the weight of the fetus, the fetus is mostly in the posture of head and hip. The normal fetal position should be that the fetal head is bent, the occipital bone is in front, and the head is inserted into the pelvis first during delivery. Medically, it is called "the first appearance". There is no scientific proof that it is possible to judge whether the baby is a boy or a girl by the height of the fetal position. None of this is accurate. I hope everyone will just use it as a reference. The important thing is that children are healthy, both men and women. Keep a peaceful mind.
Sperm and eggs in germ cells contain half the chromosomes of somatic cells, that is, 23 chromosomes. The eggs produced by women have only one sex chromosome with X, while the sperm produced by men have two kinds of chromosomes, half with X chromosome and half with Y chromosome. When the sperm with X chromosome is combined with the egg, the sex chromosome carried by the fertilized egg becomes xx, which is a female fetus. Sperm with Y chromosome is combined with egg, and the sex chromosome of fertilized egg is xy, which is a male fetus. One ejaculation can produce hundreds of millions of sperm. The combination of sperm with X chromosome or Y chromosome and egg is completely accidental, which is not controlled by the man's will and is not the woman's fault. Neither side can complain.
The so-called fetal position is the position of the fetus in the uterus. Prenatal fetal posture in the uterus is very important, which is related to whether the pregnant woman is in labor or dystocia. Generally speaking, the fetal position cannot be determined until the third trimester of pregnancy. Generally, the fetal position will slowly decline before entering the basin, and finally enter the basin. Everyone's situation is different, and the size and height of the stomach after pregnancy are also different. So it is very unreliable to judge the sex of the fetus.
