Will pregnant women feel different when they are pregnant with their daughters and sons?

Close your eyes and you can guess what everyone thinks!

What is hot and sour, what is the shape of the stomach, what is the morning sickness reaction, and even judging the birth of a daughter and son by the color of urine, what I want to tell you is: "These remarks are not reliable"!

Have a boy and a girl 1: 1?

This is also wrong.

The World Health Organization (WHO) has long given the birth population ratio, and the sex ratio of male to female is about 105. The same is true for OECD data (ranging from 102.5 to 107).

That is to say, based on 100 girls, the average male newborn should be around 105. The reason is that the natural life expectancy of boys is shorter, and the probability of death of boys is higher than that of girls.

The fetal sex ratio changes with the change of pregnancy.

You are right, the sex ratio of the fetus changes in every cycle of pregnancy. According to a study published in the Proceedings of the National Academy of Sciences (by American biologist Steven Ozark, 20 15), the survey results show that:

At fertilization, the ratio of male fetus to female fetus is 1: 1.

After 4 weeks of pregnancy (that is, before 2 weeks of pregnancy), the survival rate of female fetus is about 0.5 higher than that of male fetus.

During pregnancy 12 ~ 22 weeks, the survival rate of male fetus increased by 0.5, while the proportion of female fetus abortion increased significantly.

After 7 months of pregnancy, the survival rate of male fetus decreased slightly, but remained at about 0.5.

Therefore, after the baby is born, there are always more male newborns than female newborns.

However, all the above are based on statistical data, and biologists don't know why.

What do boys and girls feel at the beginning of pregnancy?

In the history of China, the most accurate fortune teller is Xu Fu who is proficient in Zhouyi gossip. He told Wang Wei that "Ji Bo should be a prince". As a result, Liu Bang defeated Wei Bao, took him into the harem, and then gave birth to Heng, the later Emperor China.

Xu negative is actually a magic stick, because he has a 50% chance of guessing boys and girls, and if he is right, he will ascend to heaven. If he is wrong, he will only put oil on his feet. The world was in chaos at the end of Qin Dynasty, and Xu was just a good gambler.

The feelings of pregnant boys and girls are always strange, always ambiguous and specious, but there is no scientific basis. So just listen and don't take it seriously!

I wish everyone happiness in their hearts. My son wants to have a boy and my daughter wants to have a daughter. Blessing! Blessing!
