The birth check is that the daughter gave birth to a son, and the "female to male" is too sudden. Who is wrong?

A true story around me, a woman, influenced by the idea of son preference, wants to have a boy. However, after marriage, she gave birth to two daughters in succession. This year, the woman is pregnant again. In order to avoid the disappointment of having another son, the woman and her husband agreed to know the sex of the fetus first. If it is a boy, it is necessary. If it's a girl, it's not. Therefore, when doing four-dimensional color Doppler ultrasound, they secretly recorded the moving image of the fetus, and privately asked someone to ask if it was a man or a woman. Many people said it was a girl, so they aborted the child. However, nature played a trick on people, and the child was found to be a boy after miscarriage. ......

In life, like this, because the fetus is "male to female" and "female to male", there are not a few parents who hope to fail. Why are there fetuses "male to female" and "female to male"?

Fetuses "male to female" and "female to male" are superstitious, and women are pregnant with children. They learned the sex of the fetus through various channels. Later, they found that the sex of the fetus was different from what they thought, or it was badly hurt or extremely happy, but in the end, most of them came down to "it's all fate." However, what many people don't know is that the "male to female" and "female to male" of the fetus originated from superstition.

There is a scientific common sense that the sex of a fetus is determined from the moment when a fertilized egg is formed. A fertilized egg is a new individual composed of 23 pairs of male and female chromosomes. A set of sex chromosomes plays a decisive role in the sex of the fetus. When sperm provides Y chromosome, the fetus is a boy; When sperm provides the X chromosome, the fetus is a girl. Although the sex of the fetus can only be found out in about 4 months, he will stay in his mother's stomach for about 10 months, but the sex of the fetus will not change after that. The so-called fetus "male to female" and "female to male" may be because everyone believes that some force can change the sex of the fetus, which is superstition.

There are specific reasons for the illusion that the fetus is "male to female" and "female to male"

Pregnant women and their families think that the sex of the fetus will change, not only because they lack basic scientific knowledge, but also because there are many reasons for the "male to female" and "female to male" of the fetus, which is quite confusing. Here, let's take a look at several reasons why the fetus has the illusion of "male to female" and "female to male".

① When doing four-dimensional color Doppler ultrasound, the fetal position causes gender misjudgment.

Women who are pregnant for 22-26 weeks can do four-dimensional color Doppler ultrasound to check the development of the fetus in the mother's stomach. At this time, the part used to judge the sex of the fetus has basically developed to an identifiable level, and the sex of the fetus can be known. However, some fetuses are in their mothers' stomachs and like to play hide and seek. Every time he takes a picture, he blocks important parts with a certain posture, which leads the doctor to misjudge the sex of the fetus. Mistake girls for boys, or mistake boys for girls.

② When doing four-dimensional color Doppler ultrasound, due to the influence of amniotic fluid and tissue fluid, the true sex of the fetus can't be seen clearly.

Four-dimensional color Doppler ultrasound is a very advanced medical technology, but like other examinations, it is not a perfect universal examination, and it has its own limitations. The true results of four-dimensional color Doppler ultrasound will be affected by amniotic fluid and tissues, which may lead to unclear display of many organs or key parts of the fetus. If women do four-dimensional color Doppler ultrasound, it happens that the ultrasound phenomenon does not show the important parts of the fetus well, and even doctors can't see the real sex of the fetus clearly.

(3) Using the wrong method to guess the sex of the fetus, the preconceived sex of the fetus is wrong.

After a woman is pregnant, no matter whether the baby in her belly is male or female, there are many unreliable methods circulating among the people. For example, "hot and sour girl", "pointed-bellied boy and round-bellied girl", "boys born earlier than the expected date of birth are girls born later than the expected date of birth" and so on. In fact, these are all incorrect earthwork. There are only three ways to truly identify the sex of the fetus: ultrasonic scanning, amniocentesis and villus collection. If someone guesses the sex of the fetus wrong, guess the sex of the fetus wrong first. So when I saw the real gender of the baby after birth, I thought it was "male to female" and "female to male".

Rational treatment of fetal sex

In fact, when the fetus is still in the mother's belly, people misjudge the sex of the child. After the baby was born, he saw his true sex clearly, but he didn't want to admit that he had misjudged the sex of the fetus before, so there were sayings of "male to female" and "female to male". It's still ridiculous to think about it.

The most fundamental reason for the phenomenon of "male to female" and "female to male" is that people pay too much attention to the sex of the fetus. In fact, regarding the sex of the fetus, whether the test results are what you want or not, you should cherish the fate with this little life. Don't abandon him because of a temporary result. Maybe in the future, after his birth, it will bring surprises to the whole family.
