Is there a scientific basis for flower embryo?

Flower fetus means that the first child is a girl, the second child is a boy and the third child is a daughter. On the contrary, the first child is a boy, the second child is a daughter and the third child is a boy. Haven't you heard of it? Many of us say so, and we don't know if it's accurate or not.

There is no flower tire, which is unscientific in itself. Whether you want to have a boy or a girl depends not on calculation, but on family genes. During this period, B-ultrasound can be done to diagnose the sex of men and women, about three months, and then the sex of the fetus can be detected. In the fourth month of pregnancy, four-dimensional color Doppler ultrasound examination will be clearer and the diagnostic effect will be more accurate.

First, the speed and strength of fetal heart rate

Judging whether a baby is a boy or a girl according to the beating speed of the fetal heart is also a way to predict the symptoms of a boy or a girl. If the fetal heart rate is strong and slow, it is more likely that the fetus is a boy. On the other hand, it is a girl.

Second, pregnant mothers with good memory are more likely to have boys.

Canadian researchers have found that pregnant women with boys perform better in listening, calculation and visual memory than pregnant women with girls. This result shows that male and female embryos have influence on maternal cognitive ability, and there are "important unknown factors" between the difference of pregnant women's cognitive ability and the sex of embryos. Therefore, pregnant women with boys have better memories than pregnant girls.

Third, the appetite of expectant mothers.

The male hormone naloxone secreted by the male fetal pill sends a signal to mothers that they must eat, which greatly increases their food intake. In addition, although a mother who is pregnant with a male fetus will give birth to a heavier baby, her weight gain during pregnancy is not heavier than that of a pregnant woman who is pregnant with a female fetus, indicating that the sex of the fetus does not affect the mother's weight.

At present, sex identification of babies is prohibited in China, so no matter what kind of baby is pregnant, parents are the happiest as long as they are healthy.
