Belly shape of a boy in 6 months of pregnancy

Many old people say that you can tell the gender of the baby by looking at the shape of the pregnant mother's belly. They often say: a round belly is a boy, and a pointed belly is a girl. Is there any scientific evidence for this? Is it really possible to identify a baby based on the shape of the belly? Let's discuss how many months into the pregnancy we can look at the shape of the belly to determine whether it is a boy.

How many months into pregnancy can you tell if it's a boy by looking at the shape of your belly?

The shape of a daughter's fetus

Feature 1: Belly is rounder than body curves

If a baby girl is born, the inclination of the abdomen on both sides will exceed the waist circumference when viewed from the back. It is more obvious when viewed from behind, allowing people to know at a glance that you are a pregnant woman.

Characteristic 2: The belly is not a perfect circle, but an oblate shape; the oblique line of the swallowed circle is a trapezoid

The back of the baby is flat and round, and looks like an egg standing upright. Moreover, the oblique line of the swallowing circle is trapezoidal and more prominent.

Feature 3: Belly falls down

Viewed from the side, the mother who is pregnant with a baby girl has a very pronounced body curve with a slope; her belly has a noticeable sense of sinking, her pelvis cannot stand, and the amplitude is insufficient.

Pregnant boy fetus

Feature 1: Belly shape is like a balloon

The shape of the fetus when pregnant with a boy is more obvious, just like a balloon is blown up in front of the abdomen, and nothing else changes except this balloon.

Feature 2: Round abdomen, oblique symmetry

The back of the abdomen is a perfect circle, symmetrical and detailed.

Feature 3: Straight body curves and strong pelvic bones

There are other different methods, and the inspection time is different

The fetus' reproductive organs will only begin to divide from the eighth week of pregnancy. The fetus's reproductive organs and urethra begin to form in the 8th week of pregnancy and are completely formed in the 15th week. Different gender testing methods have different testing times.

B-ultrasound

Medically speaking, B-ultrasound examination can be performed around 20 weeks of pregnancy to identify the sex of the fetus, provided, of course, that the fetus is in the right position and the ultrasound doctor can see the key parts of the baby. At this stage, the differences between boys and girls are already very obvious. As your pregnancy progresses, these differences will become more recognizable. If your baby is surrounded by enough amniotic fluid and his feet are not tucked between his legs, then the gender of the baby can usually be determined based on the B-ultrasound data in the late pregnancy.

It should be noted that the current predictions of fetal gender based on fetal movement, fetal heartbeat, and fetal sac width ratio that are widely circulated on the Internet are all inaccurate. B-ultrasound observation of the fetus's sex is to look at the male reproductive organs, not the gestational sac. Starting from around 11 weeks (80 days) of pregnancy, babies of different genders begin to show differences in appearance. At this time, the positions of all the fetus's sexual organs are prominent. In boys, this protrusion usually extends upward and intersects the spine at an angle of more than 30 degrees. Relatively speaking, the protruding position of a girl's genitals will appear to be more horizontal, and the angle between them and the spine is less than 30 degrees.

Blood test

A blood test is a quick way to determine the sex of the fetus. However, China currently does not have the technology to identify the sex of the fetus through blood tests. The closest region to having this technology is Hong Kong. Researchers have discovered that a gene called "SRY" only exists on the Y chromosome. Once its presence is detected, it means that the fetus is male. Therefore, the fetal DNA in the mother's blood is isolated to see if the SRY gene can be found, and the gender question is naturally solved. Unlike B-ultrasound, which can only detect gender characteristics when the fetus is large enough, this type of examination can be performed 7-8 weeks after pregnancy, and its accuracy is higher than B-ultrasound, reaching 99.4%.
