Can ordinary B-ultrasound tell the gender of a baby?

For the health of the baby in her belly, every mother will conduct regular prenatal checkups during pregnancy to ensure that the position and growth status of the fetus in the belly are in good condition. B-ultrasound is one of them. The baby's shape and gender can be determined through B-ultrasound. There are many types of B-ultrasound. Can a general B-ultrasound be used to identify the sex of the fetus? Let's find out together.

Can B-ultrasound be used to identify the sex of the fetus?

From a medical point of view, the gender of the fetus can be determined through ultrasound examination after a woman is 4 months pregnant. Because at 4 months old, the difference between boys and girls is already very obvious. As your pregnancy progresses, these differences will become more recognizable. But there is a prerequisite that the doctor can see the key parts of the fetus during the examination. 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 ultrasound data in the late pregnancy.

Ultrasound examinations in early pregnancy are not very accurate in determining the sex of the fetus. Because the gender of the fetus is determined by genetic genes, there is no difference between men and women in the early stages of fetal growth and development. Ultrasound is not allowed to accurately identify the sex of the fetus. Just like the growth and development of the fetus's sexual organs, it is a gradual process. It is only from around 11 weeks (80 days) of pregnancy that the appearance of fetuses of different genders begins to show differences. In the fourth month of pregnancy, that is, after 20 weeks, the ultrasound examination can basically determine the sex of the fetus without any errors. Friendly reminder: It is strictly prohibited to identify the sex of the fetus in our country. It is not allowed to do B-ultrasound examination to identify the sex of the fetus, whether it is a boy or a girl.

During the first four months of pregnancy (the first 20 weeks), the embryo is in the early stages of development and its gender cannot be determined even through ultrasound. During this time, boys and girls looked the same. All test tube embryos often have a small bud or protrusion at the sexual organ. If you are pregnant with a boy, your fetus will begin to secrete testosterone around 7 weeks of pregnancy, stimulating the growth of new buds in the genitals to form genitals and scrotum. When you're pregnant with a girl, the small bud in this genital area will grow into the clitoris and vulva.

The gender of the fetus cannot be determined by B-ultrasound at the beginning. It becomes clear gradually as the sex organs of the embryo grow and develop. It is only from around 11 weeks (80 days) of pregnancy that the appearance of fetuses of different genders begins to show differences. At this time, the position of the entire fetus's sexual organs is often 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. According to netizens' experience, if you want the doctor to see the exact gender of the fetus during B-ultrasound, pregnant women are best to lie with their back down and face up.
