Pregnancy front wall and back wall to see the gender

Pregnancy front wall and back wall to see the gender

If you only rely on the anterior and posterior walls to determine the gender of the fetus after pregnancy, there is no scientific basis. If you want to know the gender of the fetus, the best way is to go to the hospital for a detailed physical examination in time. The most common method is amniocentesis, which is also the fastest way to know the gender of the fetus. However, this method has certain risks and may cause fetal deformities after the puncture.

Fluff

Chorionic villus sampling, also known as chorionic villus sampling, is a procedure in which a thin needle is used under ultrasound guidance to enter the amniotic cavity through the pregnant woman's abdomen, uterine wall, and amniotic membrane to extract a small amount (about 20CC) of amniotic fluid. The fetus and the amniotic fluid around it are surrounded by a layer of amniotic membrane. The amniotic fluid contains many cells shed from the fetal skin, respiratory tract, digestive tract, and urinary tract mucosa, which can be used for examination. It is usually performed after 10 weeks of pregnancy. It has been 30 years since the first successful amniotic fluid culture in 1968. However, chorionic villus sampling has certain risks of causing miscarriage or fetal malformation.

The main purpose is the same as amniocentesis, which is to diagnose whether the chromosomes of the fetus are normal, but it can also be used to diagnose the sex of the fetus. The accuracy rate can reach 100%, and the results can be obtained in 2 days. Although chorionic villus sampling can determine the sex of the fetus around 10 weeks of pregnancy, it may cause miscarriage (1% may harm the fetus).

Maternal blood

Maternal blood identification is to use the peripheral blood of pregnant women, that is, capillary blood, to collect a few drops of blood from the earlobe of pregnant women, make a blood smear, and use special staining and cell morphology technology to identify the sex of the fetus. This test is relatively safe, with an accuracy rate of more than 95%. The condition is that the pregnancy is more than 45 days. Maternal blood identification will not cause miscarriage or malformation in pregnant women.

B-ultrasound

Ultrasound identification of fetal gender requires that the pregnant woman be more than 19 weeks pregnant. However, even the most experienced imaging experts can only determine the gender of the baby after three and a half months or more than three months of pregnancy, and the accuracy rate cannot reach 100%. However, it is the safest.

puncture

Amniocentesis is an invasive method of sex determination, with a 1%-3% risk of miscarriage, fetal malformation, and infection. The accuracy rate can reach about 95%. Amniotic fluid is a special fluid that reflects the various functions and certain diseases of the fetus. It contains cells shed from the fetal skin, respiratory tract and urethra. The medical community does not approve of amniocentesis for the sole purpose of determining the sex of the fetus: Amniocentesis is a procedure in which a long needle is used to draw amniotic fluid from the amniotic cavity of a pregnant woman through her sacral wall to detect the condition of the fetus.
