Characteristics of a boy at 18 weeks of pregnancy

In daily life, many expectant mothers try to guess the gender of their baby by looking at the shape of their belly. If the belly is long and pointed, everyone agrees that it is a boy, but if the belly is round, it is a girl. So is this term scientific? How to tell the gender of the baby on ultrasound report at 18 weeks of pregnancy?

How to tell the gender of the baby on ultrasound report at 18 weeks of pregnancy

It is said from the elders that the shape of a boy or girl has been determined long time ago. For example, a boy is long-shaped two months before pregnancy, while a girl is oval or round. The gender may not be correct from the B-ultrasound data, but this saying has always existed. The sooner you see it, the better. It is not easy to judge, but it is only for reference. The specific method of fetal sex identification from B-ultrasound data is:

BC data information at 7 weeks and 1 day: gestational sac 2.91.9, a boy was born

BC data information of 9W 4D: 46.630.2mm fetal sac is found in the uterine cavity, and the twin babies are all girls

60-day BC data: The gestational sac is 3.61.6MM and the baby is a handsome boy

5W 6D fetal sac: 25mm11mm boy

Data information: Gestational sac: 23, periodontal 17, periodontal 16, the baby is a little sister

46 days BC data information fetal sac: 201717 female

7 weeks 1D BC result: 322b250m gestational sac female

At 8 weeks, the periodontal was 1.6 and the one born was dry gold.

At 8 weeks, the 4128MM gave birth to a girl

It was BC at more than 8 weeks, the gestational sac was 19MM10MM, and the BC was also a boy.

It was BC at 8 weeks, the gestational sac was 19MM*10MM, and the BC was also a boy.

B-ultrasound cannot accurately infer the gender of the fetus. The only way to understand the gender of the fetus is to look at the fetus's sexual organs through B-ultrasound. Moreover, the baby's posture at that time must allow the ultrasound doctor to see his sexual organs. But even if the ultrasound doctor can see the location of the fetus's sexual organs, the image may not be clear. This will affect the accuracy of B-ultrasound determination of the fetus's gender and is prohibited.

I believe that anyone who knows a little about medicine should have a certain understanding that the claim of using B-ultrasound data to identify the sex of the fetus is not necessarily accurate. Therefore, I would like to remind everyone that the method of fetal gender identification and prediction is not 100% accurate and should not be believed blindly.

There is a saying among the old people that "a boy is born with a short head and short thighs", which means that in most cases, the characteristic of a boy is a short head and short thighs. This is actually not scientifically proven.

Some fetuses have a large head position. For example, if the biparietal diameter of the fetus shown by B-ultrasound at 30 weeks is the indicator value of 31-32 weeks of pregnancy, then the error between the biparietal diameter and the femoral length may exceed 2; and if the biparietal diameter of some fetuses is in line with the gestational age, but the growth and development of the legs cannot keep up with the gestational age, then the error between the biparietal diameter and the femoral length may also exceed 2.

The data such as fetal femur length, fetal abdominal circumference, fetal biparietal diameter in B-ultrasound reflect the growth and development of the fetus. It is not reasonable to identify the sex of the fetus based on these data. Gender is determined based on the reproductive organs; the biparietal diameter and femoral length of the fetus cannot be used to determine gender.

Characteristics of having a boy

During pregnancy, the human body will undergo some changes, such as an enlarged belly and the formation of a pregnancy line. The extracellular fluid of the pregnant woman will also undergo corresponding changes due to pregnancy. Many people believe that by carefully observing these changes, they can roughly calculate whether the pregnant woman is carrying a boy or a girl. Characteristics of a boy pregnancy include:

1. The abdomen is pointed, which means the probability of having a boy is high.

2. A protruding belly button means it’s a boy.

3. The pregnancy line is thin, long and straight.

4. The early B-ultrasound gestational sac is strip-shaped. For example: On the 52nd day of pregnancy, the gestational sac was shown by ultrasound with an anterior to posterior 4.2 and an posterior to posterior 2.1.

5. The value of fetal biparietal diameter-fetal femur length exceeds 2.

6. Pregnant women with anterior placenta are more likely to have a boy.

7. If the pH value in urine test during pregnancy continues to rise, it means you are pregnant with a boy.

8. In the later stages of pregnancy, due to the increase in androgen levels when carrying a boy, the pregnant woman's thighs, armpits, nipples, and neck will become darker.

9. If the tip of a pregnant woman's nose becomes larger, it means she is pregnant with a boy.

However, experts have warned that the above methods are for reference only and cannot guarantee accuracy. In reality, the method of determining the sex of a baby based on pregnancy symptoms is not much better than flipping a coin.
