How long does it take to know the gender of a pregnancy?

Many couples who are pregnant are concerned about one question: How long does it take to know the sex of the fetus? Nowadays, medical technology is relatively advanced. You only need to go to the hospital for a B-ultrasound examination to get it. In addition, if you want to know the gender of the fetus, you can also do DNA blood tests, hair follicle puncture biopsy, amniocentesis and other methods. But no matter whether the baby in the belly is a boy or a girl, he is the fruit of the couple's love. Prospective parents should pay more attention to whether the fetus is healthy and whether its growth and development are normal, rather than caring about gender.

How long does it take to know the sex of the fetus?

1. B-ultrasound examination. At this stage, B-ultrasound is a very accurate way to distinguish whether the baby is a boy or a girl. Although the gender of the baby can be detected at around 18 weeks of pregnancy, during B-ultrasound, the baby may be facing in the wrong direction or with legs crossed, making it impossible to see the position of his or her genitals. B-ultrasound assessment of fetal gender requires that the pregnant woman be more than 19 weeks pregnant. However, even the most experienced imaging diagnostic experts can only tell the baby's gender around three and a half months or more than three months of pregnancy, and the accuracy cannot reach 100%. But the safety factor is the highest.

2. DNA blood test, DNA blood test is the assessment of maternal blood. The technology of genetic engineering can be used to use the blood of the pregnant mother's vein to determine the gender of the fetus. There is no risk to the fetus and pregnant mother. According to the report from the blood DNA test laboratory, the accuracy of the current assessment can reach up to 98%. Gender inference can be made based on sex chromosomes, especially for boys, with a strong positive response. The baby will be examined after 8 weeks and the results will be available in about 3 days. More importantly, this method will not cause any impact on pregnant women and fetuses.

3. Cricketary puncture biopsy. Pregnant women can undergo cricketary puncture biopsy at 10-12 weeks of pregnancy. Cricketary puncture biopsy is usually performed when the baby may have serious gender-related problems, such as to test for chromosomal abnormalities such as Down syndrome. This cricketary puncture biopsy is used to identify the gender of the fetus. Although the use of Vaginal Sampling can determine the gender of the fetus around 10 weeks of pregnancy, it may lead to miscarriage. 5. Ultrasound scanner. Ultrasound is a sound wave frequency and has no adverse effects on the fetus. However, this method must be used when the baby is 3-4 months old, so that the results will be more accurate. However, when using ultrasound to diagnose the sex of a fetus, the accuracy of confirming a boy is over 95%, while the reliability of confirming a girl is only about 85%.
