Is it a big head of a boy or a girl?

As we all know, in fact, at some point in pregnancy, we can see whether the baby is male or female according to the different physical characteristics of each baby. However, due to the increasing preference for sons over daughters, doctors are not allowed to reveal whether they are male or female to their families. This also largely avoids the phenomenon that some people will have surgery when they see a girl. So, is the fetal head too big a boy?

The fetal head is too big. Is it a boy?

Just because the doctor says the baby's head is big doesn't mean it's a boy. If the fetal head is big, it may be that the fetus is bigger. At this time, it is necessary to control the diet to avoid the fetal head being too large to affect the delivery. If the fetal head is too large, we can consider whether the fetus develops rapidly in the uterus. Pregnant women are advised to check for diabetes or overnutrition. Therefore, pregnant women should insist on prenatal examination, find problems early and solve them in time. Fetal head size may also be affected by genetic factors.

Causes of fetal head enlargement

1. If the fetal head is only slightly older than the normal gestational age, but there are no other abnormalities, it may be caused by the rapid development of the fetus, not pathological. This is the most common kind of big head. Generally speaking, as long as it is not too much, there is actually no problem.

2. If women do not supplement enough nutrition during pregnancy, some diseases may occur, such as failing to supplement cod liver oil and calcium tablets in time, appearing big head, late fontanel, sparse hair and sweating. , may be rickets. So, what is the reason for the big fetal head? According to the above, it may also be a lack of necessary nutrition.

Both boys and girls are little treasures in their parents' hearts. Although the gender is different, the roles are completely different. We all know that boys are generally disobedient, and girls are parents' good babies and intimate cotton-padded jackets. Therefore, no matter whether we are male or female, we should be mentally prepared and not have bad ideas.

How much is a boy's 23-week double crown diameter?

1. This is a false proposition. It is unscientific to see whether the fetus is a boy or a girl by the biparietal diameter of the fetus. There is no reliable evidence to prove it at present.

2. The standard value of fetal biparietal diameter at 23 weeks gestation is 5.80%±0.44cm. The biparietal diameter of some fetuses is too large, which is due to the pregnant mother's good nutrition and small activity, resulting in excessive fetal development.

3. The fetal biparietal diameter should be greater than 9.3 cm at full term. According to the general rule, after 5 months of pregnancy, the development standard of biparietal diameter is basically the same as that of the month of pregnancy. In other words, the biparietal diameter of the fetus is about 7 cm at 28 weeks of pregnancy, 8 cm at 32 weeks of pregnancy, and so on. After 8 months of pregnancy, it is normal for the fetal biparietal diameter to increase by about 0.2 cm per week.

In fact, it is unscientific to distinguish sex by the biparietal diameter of fetal development. As people in the new century, we should resist this view. If you want to know the sex of the fetus, you'd better go to the hospital for a routine examination.
