There is a significant difference in opinions among people about whether a baby will be a boy or a girl, with elders generally hoping to have a son as the torchbearer for the next generation. In fact, such thoughts are already very feudalistic and not a view recognized by modern society. However, some people still feel that if the fetus is smaller, the probability of it being a girl is higher. Then, does a smaller fetus always mean a girl?

Is a small fetus usually a girl

There is a saying that if a pregnant woman with a small fetus gives birth to a girl, she will have a small fetus giving birth to a girl. In fact, there is no scientific basis for this, just a matter of probability. The gender is only divided into male and female, each accounting for 50% of the chance. A small fetus giving birth to a girl is not certain, and there are also cases of a small fetus giving birth to a boy. Therefore, such folk names should not be taken seriously. Whether it is a boy or a girl, as long as they are healthy, it is not necessary to follow the crowd, which will affect the mood of the pregnant woman and is not good for the fetus.

What are the causes of a small fetus

In fact, many characteristics shown by the fetus are due to genetic factors, such as if the fetus is too small, it may inherit the characteristics of the parents. If the father and mother are small during the fetal stage, the probability of giving birth to a small baby is relatively high! Naturally, if the mother cannot supplement nutrition in a timely and comprehensive manner during pregnancy, the fetus will not be able to get enough raw materials during the development stage, and of course, the growth will be affected, which is very likely to cause the fetus to be small. If the examination finds that the fetus is small, it also needs to consider whether the pregnant woman or the fetus itself has chromosomal abnormalities, and chromosomal or genetic abnormalities are also one of the reasons why the fetus is small that cannot be ruled out.

When a mother finds that the growth of the child in her abdomen is smaller than the normal standard, she must pay more attention. Although this situation cannot tell the gender of the child, it does reflect that the growth of the child is not very good. It is necessary for pregnant women to supplement more nutrition so that the fetus can get more energy and grow bigger.

How to see the gender with 4D ultrasound

In our country, it is forbidden to investigate the sex determination of the fetus. If a doctor exposes or hints at the sex of the fetus in any way, he may be held legally responsible. Therefore, when doing a 4D ultrasound, the doctor generally avoids the lower body of the fetus and does not show the male reproductive organs of the fetus on the image. Moreover, for young parents, whether it is a boy or a girl, it is the product of this family. Understanding the healthy growth and development status of the fetus is the actual meaning of doing a 4D ultrasound.

However, there are some folk names for this, which are based on some data information from B-ultrasound, such as the fetal sac, the biparietal diameter, and the femur value. However, this method of identification is not necessarily accurate.

Because pregnant women have individual differences, the timing of doing a 4D ultrasound should vary from person to person. Generally speaking, the best time to take a 4D ultrasound is between 24-28 weeks of pregnancy. If it is to take a full-body image of the fetus, it is possible to do a 4D ultrasound in the early pregnancy period. Since the fetus is not very big at this time, it is possible to take a full-body image of the baby. However, it must be noted that it is not recommended to do a 4D ultrasound between 1-2 months, and there is still a lot of controversy about whether it is possible to do a 4D ultrasound at this time range. If it is to check for external defects of the fetus, it should be done during the middle or late stages of pregnancy.
