Methods for determining the gender of a baby during the third month of pregnancy

After being pregnant for a period of time, female friends will very much want to know the gender of the fetus in their belly, so they want to see whether they are pregnant with a boy or a girl. If they really want to know, they can use DNA blood tests and amniocentesis, but no matter which method is used, it will cause more or less harm to your body and the fetus, and knowing the gender in advance is also illegal.

Pregnant women can know the sex of the fetus through DNA gender identification as early as 7 weeks of pregnancy, with an accuracy rate of up to 99.4%.

Maternal DNA blood test: Genetic engineering technology can be used to take blood from the mother's vein to determine the sex of the fetus. There is no risk to the fetus or mother, and gender is inferred through chromosomes.

There are three methods that have been medically and scientifically proven to determine the sex of the fetus: color Doppler ultrasound to determine the sex of the fetus, DNA blood test, and amniocentesis. Although these three methods have been medically proven to be useful for testing the sex of a fetus, color Doppler ultrasound alone has many disadvantages in determining the sex of a fetus.

Many pregnant women identify the sex of their fetus by simply looking at the sex of the fetus through color Doppler ultrasound, and then the gynecologist will tell them the sex of the fetus. There are several problems with this detection method, the first of which is the issue of accuracy. Many factors can affect accuracy, such as the model of the B-ultrasound machine. Older models may prevent gynecologists from seeing clearly and lead to misjudgment.

The position of the fetus can also affect the accuracy. For example, if the fetus's sexual organs are pressed, it can also affect the obstetrician's and gynecologist's judgment. Of course, the experience, skills, and years of service of the obstetrician and gynecologist will affect the accuracy, so there are many uncertainties in identifying the sex of the fetus through B-ultrasound, and the accuracy rate is generally only about 70%.

In recent years, advances in genetics and medicine have enabled pregnant women to test the sex of their fetuses through blood tests. It is no longer necessary to use color Doppler ultrasound to determine the sex of the fetus. The advantages of DNA blood testing are very obvious and prominent. The advantages are as follows:

It only requires drawing blood from the mother, and the process is simple and safe

It is a non-invasive test and does not increase the risk of miscarriage.

To be tested, the following 4 requirements must be met:

1. The gestational age must be more than 6 weeks.

2. No male baby has been born within one year,

3. No blood transfusion, major surgery, organ transplantation,

4. The blood types are common: A, B, AB, and O. If the above four conditions are met, the accuracy rate will reach 99.4%-99.5%.
