The method of detecting the gender of fetus mainly includes traditional B -ultrasound, amniotic puncture detection, and villi sampling detection. The best time for detection is also different due to different selection methods.
1.B Super Test -after four months of pregnancy
As far as the current level of medical development is concerned, the most intuitive and clear identification of the sex of the fetus is the B -ultrasound.However, identifying the sex of the fetus has time limit. Generally, around April of pregnancy, the B -ultrasound can know the gender of the fetus.Because from the perspective of the growth and development of the fetus, before 12 weeks of pregnancy, the child’s external genitalia has not yet fully developed, and it is difficult to determine the gender from the B -ultrasound. By the weekend of the 12 weekend, the fetal external genitals have developed.Genital determines gender.Whether the B -ultrasound can be accurate depends on the experience of the doctor and the impact of fetal position.
2. Pine membrane puncture-17-21 weeks of pregnancy
The main function of amniocestinal puncture is not to detect fetal gender. It is mainly used for the auxiliary examination of Tang’s screening and the judgment of certain genetic diseases.Compared to traditional B -ultrasound, the biggest advantage of amniotic perception detection is that it can detect whether the fetus has abnormalities in chromosomes.The best examination time for amniocemic puncture is 17-21 weeks of pregnancy, but expectant mothers need to remember that amniotic stabbing is a creative examination, and 1%of the risk of abortion.Use this method to check the sex of the fetus.
3. Sample sampling-10-14 weeks of pregnancy
Similar to the detection of amniotic wake, the method of sampling of fluff is also mainly to diagnose whether the fetus’s chromosomes are normal. In time, the sampling of fluff is usually performed at 10 to 14 weeks of pregnancy.This method is very risky and it is easy to hurt the fetus. In severe cases, it may cause disability or even abortion in hands and feet, so you must choose carefully.
In addition, it is necessary to remind everyone that in our country’s use of various methods for fetal gender testing, and choosing fetal gender is illegal.You should put the health of the fetus first, establish the concept of equality between men and women, and make scientific fertility.
