Doing B-ultrasound to see the boy and girl

Many pregnant women want to know whether they are pregnant with a boy or a girl. In fact, you can know whether you are pregnant with a boy or a girl through B-ultrasound with a relatively high accuracy. However, in our country, the requirements are different and the gender of the baby is determined by B-ultrasound. So, at how many months can we tell the baby’s gender through B-ultrasound? What other methods are there to determine the sex of the fetus?

1. March-April

Generally, it is possible to determine whether the baby is a boy or a girl through B-ultrasound around March or April, but it also depends on the position of the fetus. When the fetal position is perfect, it is correct, but don't be too confident in your judgment. The most intuitive way to determine the sex of the fetus is B-ultrasound, which can clearly show every organ and position of the fetus, including sexual organs. However, our current Chinese law stipulates that privately informing pregnant women and relatives of the gender of the fetus is against the law. Another way to identify the sex of the fetus is amniocentesis, which is to test the sex chromosomes, which has the highest accuracy. However, amniocentesis is very prone to infection, which may harm both the pregnant mother and the fetus.

2. Amniocentesis

Amniocentesis is mainly used to perform service tests on patients with Down syndrome. It can also test whether the sex chromosomes of the fetus are normal. The best time to test is around 16-20 weeks of pregnancy. In addition, pregnant mothers should be reminded that amniocentesis is a traumatic test and there is a certain degree of risk of miscarriage. If parents do not have necessary reasons, it is recommended not to use this method of testing.

3. DNA blood test

The DNA blood test predicts the gender of the fetus by analyzing part of the fetus's DNA in the pregnant woman's blood. It is a quick and safe method. And as the fetus grows, the concentration of fetal DNA in the mother's body will become higher and higher, especially reaching the maximum after 2 months of pregnancy, and the accuracy of DNA blood tests will reach 98%. Therefore, this type of test is best performed when the pregnant woman is about 2 months pregnant. The risk and risk are almost zero. It is a relatively safe method that is often chosen and recognized. Since mainland China does not allow testing for fetal gender identification, the blood test (sending pregnant women's blood for fetal gender identification) projects in Hong Kong and other places are very popular among mainland pregnant women.

Generally speaking, when you are three or four months pregnant, you can use B-ultrasound to determine whether the baby is a boy or a girl. It is important to note that although the accuracy of B-ultrasound in distinguishing the gender of a baby is high, it is not 100% accurate, so there are cases of misjudgment.
