How long can pregnancy test out boys and girls

Methods 1. Amniocentesis: amniocentesis is mainly used to diagnose whether the fetus has chromosome or neural tube defects. It is usually performed at 16-20 weeks of pregnancy. Because we can know the chromosome of the fetus, we can also know the sex of the fetus. The accuracy is 99%, but there is a 1% chance of miscarriage. Therefore, the medical community does not approve of amniocentesis just to determine the sex of the fetus.

Methods 2. Chorionic villi collection: Although the chorionic villi collection can be used to determine the sex of the fetus at about 12-14 weeks of pregnancy, it may cause abortion (3% - 5%), and may also damage the fetus, resulting in the deformity of its hands and feet. Therefore, it is best not only to test the sex of the fetus and accept this test.

Method 3. Ultrasound scanning: when using ultrasound to diagnose fetal sex, the accuracy of male infant is more than 90%, while the reliability of female infant is only about 80%. Infants must be in 3-4 months with high accuracy. This method is mainly using sound waves, so up to now there is no bad effect on the fetus, so it is also the most common method.
