This is usually a boy if you have a B-ultrasound scan

, everyone will want to know whether they are pregnant with a boy or a girl. The first thing is to prepare the baby's clothes, and the second thing is to give the baby a name. The following is a B-ultrasound single, which is usually a boy. B-ultrasound only shows this, which is usually a boy 1

1. The two values ​​of the gestational sac are about twice the value of one of them

In the early stages of pregnancy, B-ultrasound is usually taken , to see whether the fetus is developing healthily, and the shape of the gestational sac can be seen from the inside. Generally speaking, three numbers on the gestational sac will be displayed, such as 4.0cm*4.0cm*2.0cm, or 4.0cm*3.8cm*3.5cm, etc. , the size of the gestational sac of different people is different.

However, if the two-digit number of the gestational sac is twice the one-digit number, a value such as 4.0cm*4.0cm*2.0cm will most likely indicate a boy.

2. Renal pelvis separation

Generally speaking, when doing a four-dimensional color ultrasound at 22 to 26 weeks of pregnancy, some pregnant women can see the words "renal pelvis separation" on the B-ultrasound. Many of them People don’t understand and think there is something wrong with the fetus.

But in fact, if the separation of the renal pelvis does not exceed 10mm, it is normal, and this data mostly shows that the pregnancy is a boy, because this phenomenon occurs in boys 90% of the time.

Because the separation of the renal pelvis is mostly caused by the fetus holding back urine, there will be no problem after urinating after birth. However, if the separation of the renal pelvis continues to grow as the fetus grows, it may be due to growth. If something goes wrong, pay attention.

3. The value obtained by subtracting the femur length from the biparietal diameter continues to increase

Occasionally look at the value obtained by subtracting the biparietal diameter of the fetus from the femur length. If it is greater than 2.0 or 2.1, the accuracy of judging whether it is a boy or a girl is not high. However, if starting from 24 weeks of pregnancy, each examination finds that the two values ​​are getting larger and larger. The difference between the values ​​from 24 weeks of pregnancy will be more than 1.7, and the greater In the third trimester of pregnancy, the difference becomes larger. If it reaches 2.0 or above 2.1 by 30 weeks of pregnancy, there is an 80% chance that you are pregnant with a boy.

Generally speaking, if these three conditions can be seen on the B-ultrasound, the chance of conceiving a boy is relatively high.

Of course, any chance is not 100%. Just like directly taking a B-ultrasound to detect male and female is not 100% accurate. It also needs to be based on the gender of the child after birth. This can only be used as a Reference value only.

However, no matter it is a boy or a girl, it is your own baby, as long as it develops healthily, if you are worried about buying the wrong daily necessities for your child, you can buy some that can be used by both men and women, and others can wait until the child is born. Just buy again. B-ultrasound only shows this, which is usually a boy 2

Many people know that B-ultrasound can detect the gender of the fetus, but generally speaking, medical staff are not allowed to reveal the gender of the fetus due to policy reasons in China. However, the method of determining gender based on B-ultrasound results is still spread by many people. Among them, it is a common method to determine whether a boy is a boy based on whether there are two points on the B-ultrasound results.

We all know that there are big differences in the reproductive organs between men and women, and the fetuses will also have this difference. When doing B-ultrasound examination, the fetal reproductive parts will be significantly different, so B-ultrasound This difference will also show up in the inspection results.

At this time, if you see two dots on the B-ultrasound examination results, you can basically judge that it is a boy. If there are three horizontal lines, you can basically judge that it is a girl.

Characteristics of B-ultrasound that the fetus is a boy

Although the sex of the fetus can be basically judged based on the B-ultrasound result of the upper two points and the horizontal line, due to the position of the fetus, there may be B-ultrasound The reproductive parts of the fetus under ultrasound are blocked and not exposed. Although the gender cannot be judged based on this feature at this time, it can also be judged based on the following methods:

1. Look at the B-ultrasound examination picture Is there an obvious bulge? If it is and resembles a fungus, then it can be basically determined that the fetus is a boy;

2. Look at the length and width of the baby on the B-ultrasound result chart. If the length and width are If the gap is large, the fetus is likely to be a boy.

Tips:

The above two methods are the characteristics of B-ultrasound examination of pregnant boys, while the B-ultrasound characteristics of girls are opposite to those of boys. According to the B-ultrasound results, it is not Those who know the gender can also use other quick gender prediction methods to predict boys and girls, but the accuracy may not be as accurate as B-ultrasound gender prediction. In addition, you can also ask the doctor during the B-ultrasound examination. Although the doctor cannot directly state the gender, some doctors will reveal it implicitly. Whether they can understand it at this time depends on the understanding ability of the pregnant parents. If there is this on the B-ultrasound sheet, it is usually a boy 3

Is there any hint of male and female on the B-ultrasound sheet?

1. It will be printed on the color ultrasound sheet. There are two lines on the far right of the top, which are composed of English letters and numbers. The first line is the date, and the second line is the time. If the first line is M If it starts with F, it means male. If it starts with F, it means female. The T at the beginning of the second line means time.

2. The small English letters Qual high on the four-dimensional color ultrasound sheet. 1 means girls and 2 means boys.

3. See the gender of the fetus clearly through four-dimensional color ultrasound.

What is the best time to do B-ultrasound to see men and women?

It is best to use four-dimensional color Doppler ultrasound to see men and women, preferably after 15 weeks of pregnancy. Because before 12 weeks of pregnancy, the reproductive organs of male and female babies look the same, just a little bud. After 12 weeks of pregnancy, they begin to develop differently. The small buds of female babies will develop separately, and The male baby's penis begins to protrude and develop into a small penis.

This series of development can only be clearly identified through four-dimensional color ultrasound after 15 weeks. Therefore, it is not possible to determine gender through four-dimensional color Doppler ultrasound too early.

The above is a brief introduction to whether there are male and female hints on the B-ultrasound sheet. In fact, ordinary B-ultrasound charts also have hints of men and women. In the early stages of pregnancy, generally female babies who are rounder are likely to be larger, while male babies who are longer are more likely to be larger. In fact, as long as a healthy baby is born, regardless of whether it is a boy or a girl, it is happiness.

It is impossible to determine whether it is a boy or a girl from the B-ultrasound. The B-ultrasound mostly indicates the development of the fetus and the development of the placenta.

Commonly used methods to check the gender of the fetus include: ultrasound, amniocentesis and non-invasive DNA. Among these examinations, ultrasound is usually performed around four months of pregnancy; while amniocentesis is relatively risky and has It may lead to miscarriage; non-invasive DNA can identify the gender of the fetus through chromosome testing, which is more accurate, but the cost is higher. Currently, national law prohibits fetal gender identification.

During pregnancy, you should have a nutritionally balanced diet and eat small meals frequently. Whether it is a boy or a girl, the health of the baby is the most important, and it is recommended to have timely pregnancy check-ups.
