Amniotic fluid puncture is a prenatal surgery for pregnant women, and many people believe that amniocentesis can determine the gender of the fetus. So, how much do friends know about amniocentesis? Next, the editor will provide a detailed introduction to this aspect, hoping to be helpful to everyone. Please listen to the editor's introduction.
1. Maternal DNA blood test: Genetic engineering technology can be used to determine the gender of the fetus by taking blood from the maternal veins. There is no risk to the fetus or mother, and the reliability of the test is about 98%. Gender inference can be made through chromosomes, especially for male babies, with a strong positive response. The baby will undergo a check-up after 8 weeks and the results will be obtained in about 5 days.
2. Hymenoplasty: Hymenoplasty is mainly performed to diagnose whether the fetus has chromosomal or neural tube defects, usually performed between 16-20 weeks of pregnancy. Since the chromosomes of the fetus can be determined, the gender of the fetus can also be known. The accuracy can reach 99%, but there is a 1% chance of miscarriage. Therefore, the medical community does not approve of amniocentesis for the sole purpose of determining the gender of the fetus: amniocentesis uses a long needle to extract amniotic fluid from the amniotic cavity of the pregnant woman, thereby detecting the condition of the fetus. Amniotic fluid is a special liquid that reflects various functions and certain conditions of the fetus. Amniotic fluid contains cells shed from the fetal skin, respiratory tract, and urethra.
3. chorionic villi sampling: Although chorionic villi sampling can determine the gender of the fetus around 12-14 weeks of pregnancy, it may cause miscarriage (3% -5%) and may also harm the fetus, resulting in incomplete limbs. Therefore, it is best not to undergo this test solely for the purpose of determining the gender of the fetus.
4. Ultrasonic scanning: Ultrasonic waves are a type of sound wave, and reports so far have shown that they have no adverse effects on fetuses, so they are widely used in the obstetrics and gynecology industry.
The above is the content about amniocentesis to determine fetal gender that the editor has introduced to you. After reading the editor's introduction, is there anything else that you don't understand about this aspect? Amniotic fluid puncture can still be quite painful and harmful to the health of pregnant women, so it is best not to do it unless absolutely necessary.
