The gender of the child is the top concern of all mothers and fathers. But in fact, in what month does the sex of the fetus begin to form? How do I know if a baby is a boy or a girl? The following 5 methods will help parents understand more about this.
Looking at ultrasound, how to know a boy or a girl? Ultrasound is the way that medicine is used to check the development and sex of the fetus . This is a method that uses sound frequencies as high as more than 20 thousand Hz. When the machine emits this wave, they hit the uterine muscle and bounce back. The degree of the bounce wave will inform doctors about the thin, shallow depth of the uterine wall. From that information, the doctor will synthesize and give the mother details about how life is forming in the womb.
Currently, the ultrasound types are widely popular under 3 forms: 2D, 3D and 4D ultrasound.
Below is a picture of a son's ultrasound:

With this ultrasound, images are provided to the pregnant mother in a dimensional form. This is a simple form of ultrasound, which provides only a horizontal wave image of the ultrasound. Therefore, images of the fetus in this way are only visible in black and white.
Unlike 2D, 3D ultrasound is capable of transmitting frequencies that oscillate in many dimensions at the same time. Therefore, the resulting images will be serial. As a result, the pregnant mother has a 3-dimensional image of the fetus, allowing her to have a fairly realistic picture of the fetus inside.
4D ultrasound knows boys or girls? This ultrasound will be a lot more complicated than the two above. The machine will first collect 3-dimensional images and then synthesize the images and information into a series of results. Thereby creating moving images. With this ultrasound mother can see the baby is moving as well as how to react during the ultrasound.
This is a method used to check for chromosomal abnormalities in the fetus. The doctor will take a sample of the lining that surrounds the embryo, then take it for testing and analysis. With this way, it will help to detect early diseases as well as abnormal symptoms in the womb. However, this method also helps parents to know the sex of the baby.
Usually, if this method is used, a sample is taken from 10-12 weeks of pregnancy.

With this way, the mother will be able to take a sample of guava juice from the uterus and be tested. However, not all mothers are prescribed amniocentesis.
Doctors often ask mothers to do this test if necessary and mothers are at risk of complications from pregnancy, so special monitoring is needed.
Amniocentesis can be a bit painful because the doctor has to use a long, small needle through the abdomen into the uterus.
This method is used to test chromosomes of the fetus. Therefore, it can help the doctor know the exact gender of the baby is a boy or girl.
With the amniocentesis , pregnant mothers can perform from the 15th week of pregnancy. However, this is also a method that can cause certain effects to the fetus (it can cause miscarriage, usually 1%). Therefore, if not because of predictions about fetal abnormalities, most doctors do not encourage mothers to use this method just to know the sex of the baby.
The NIFTY Test is known in medicine as a non-invasive prenatal test. This is the primary test with the aim of identifying chromosomal abnormalities of the fetus.
This test method is much safer and more accurate than amniocentesis. The mother was given a 10ml blood sample and waited within 10 days to get the results. Diseases such as cleft palate, Down, hearing loss, ... can all be detected early thanks to this method.
Pregnant mothers can know the sex of the child through this way from the 10th week onwards. At this time, the child's body parts were almost complete. Therefore, the NIFTY Test method will bring high accuracy and safety for both mother and fetus.
With this method, the mother will receive a blood sample. The doctor tests and analyzes the fetal cells in maternal blood. If the blood sample appears to have a Y chromosome, it means the mother is pregnant with a boy. And vice versa, if there is no Y chromosome, the mother becomes pregnant with the baby girl.
If the sex of the fetus is tested in this way, the pregnant mother can completely perform it from 10 weeks of pregnancy. Moreover, this is one of the methods to tell the sex of the baby to more than 90% accurate.
The identification of the child's sex through ultrasound can be done from 11 weeks of pregnancy onwards. However, accuracy and clarity will depend on each week of pregnancy, namely:
If you do an ultrasound on the 11th week, you can know exactly about 40-70% of the fetus's sex.
From 12-14 weeks onwards, sex determination by ultrasound can be correct up to 70-80%.
And if from the 16th week of pregnancy, almost 80-90% of the doctors were able to accurately inform the parents of the child's sex.
In addition, the remaining cases may have to wait longer because the baby's lying position makes the doctor unable to see accurately. In this case, 4D ultrasound can help parents no longer need to guess the sex of their child nervously.
