Amniocentesis is a type of examination commonly performed during prenatal care for contemporary pregnant women. Amniocentesis can check a variety of items. The more widespread function of amniocentesis is to distinguish the gender of the fetus in the mother’s womb. In fact, there are still many ways to determine the gender of the fetus. So, how accurate is the amniocentesis result in determining the sex of the baby?

1, How accurate is the amniocentesis for determining the gender of the fetus?

Amniocentesis directly examines the DNA of the test tube embryo and can accurately determine whether it is a boy or a girl, with an accuracy of up to 99%.

Note that in China, it is strictly prohibited to do fetal gender determination evaluation, so the amniocentesis report will not explicitly state the gender of the fetus, but always reflect whether there are abnormalities in the number and structure of sex chromosomes, unless the sex chromosomes of the fetus have abnormalities, such as 47XXY, etc.

2, How to look at the gender of amniocentesis results?

We can determine the gender of the fetus according to the sex chromosomes in the amniocentesis report.

Specific practice: if there are 22 pairs of normal chromosomes plus a pair of chromosomes xy, then it indicates that it is a boy. If there are 22 pairs of normal chromosomes plus a pair of chromosomes xx, it is a girl.

Note: Generally, the last chromosome in the amniocentesis result sheet is obscured by something, which is because in China, the law and regulations strictly prohibit fetal gender determination, so it is best for parents not to pay too much attention to fetal gender determination and focus on whether the fetus is healthy.

3, What are the pregnancy period inspections for determining fetal gender determination?

During pregnancy, in addition to amniocentesis, there are also the following methods that can accurately determine fetal gender determination.

1, DNA Blood Test

When the pregnant woman has been confirmed to be 8 weeks pregnant by B-ultrasound and the fetus is normal, fetal gender determination can be detected, with an accuracy of up to 98%, and more importantly, this method will not cause any impact on the pregnant woman and the fetus.

2, Chorionic Villus Sampling

Pregnant women can identify fetal gender determination around 10 weeks of pregnancy based on chorionic villus sampling, but generally this chorionic villus biopsy is used only when there is a serious problem related to gender in the baby. It is best not to accept this kind of test just to know the fetal gender, as it may cause miscarriage (3%～5%) and may also harm the fetus, causing malformations of hands and feet.

3, Ultrasound Scanner

Ultrasound is a sound wave frequency, which has no adverse effect on the fetus, but this method must be accurate in the 3-4 months of the baby. However, in the case of using ultrasound to determine fetal gender, the accuracy of male infants reaches more than 95%, and the reliability of female infants is only about 85%.

Detailed introduction in the text shows that the accuracy of amniocentesis for fetal gender determination is still very high, with an accuracy of up to 99%, which can be said to have basically no deviation. If you are a pregnant woman who wants to undergo amniocentesis, then you also don’t have to think that you can understand fetal gender determination, doctors are not easy to tell you the gender.
