What do the old people often say about "women turning into men" and "men turning into women"?

When is the gender of the fetus determined?

I believe many people have heard of such an "oolong" situation. They thought it was a boy or a girl, but after the child was born, the situation turned upside down. This is also a big surprise and impact for the entire family. , some people have even begun to doubt the accuracy of B-ultrasound, and some people are superstitious about "reincarnation".

In fact, the gender of the fetus is determined the moment the fertilized egg is combined, so there is no such thing as "transfer".

We all know that a fertilized egg is determined by chromosomes. The egg contains an It is determined by whether you carry the X or Y chromosome.

After knowing that "rebirth" is superstitious, some people will question whether there is a problem with the accuracy of B-ultrasound? Just like my mom’s friend Aunt Xiaoyue.

Usually when the fetus is about 4 months old, their gender characteristics will be revealed. Then after the B-ultrasound examination shows that it is a boy or a girl, there is an error in the result. This phenomenon is collectively referred to as It is "female transforms into male, male transforms into female".

So what is the reason for the situation of "female transforming into male, male transforming into female"? These two reasons should be understood early.

The fetus is too small and the development of the reproductive organs has not been obvious, so it is difficult to see. As mentioned earlier, the gender characteristics of the fetus will appear when the fetus is about 4 months old. At this time, the gender of the fetus can be identified as male or female. However, some mothers are anxious to test the gender of the fetus earlier, so it is possible. This kind of comeback occurs.

However, there are still some pregnant mothers who go to check the gender after 4 months, but there is still a reversal phenomenon. The main reason is that the development status of each fetus is different. Some fetuses develop Relatively fast, some fetuses develop more slowly, and the reproductive organs of male babies develop later than those of female babies, so people will mistakenly think that male babies are female babies.

The baby is naughty and sees from different angles. Many pregnant mothers say that the baby will be very uncooperative during B-ultrasound and "hide and seek" in the mother's belly. Every time an important part of the baby needs to be photographed, he will hide and not be photographed. It is because of the baby's naughty that the doctor may Misjudgment occurs when you can't see clearly.

Especially when babies are playing with the umbilical cord as a toy, the umbilical cord will be added between the two legs, which may lead to errors in judgment. But usually doctors won’t jump to conclusions without really seeing clearly.

Finally, I would like to say that whether parents want to know the gender of their baby early out of curiosity or out of a preference for boys over girls, in fact, there is no need to know the gender of their child so early.

Wouldn’t it be more surprising to wait for the arrival of the baby with anticipation? And whether the baby is a boy or a girl, they are all their babies, and they are loved equally, right?

In addition, if you want to prepare infant products for your baby, you can prepare some unisex products so that both male and female babies can use them. In addition, it is very convenient to buy things now, so you don’t need to stock up too much specifically for your baby. Sometimes we buy too many things and don’t use them, but waste them. When we really need them, it’s too late to buy them again. We can save when we can. There will be more places for babies to spend money in the future, don’t you think?
