Now China's population distribution is more men than women. Naturally, many people want to know the gender of their children when they are pregnant. However, the first thing to make clear is that China's laws prohibit non-medical fetal gender identification, that is to say, hospitals will not do medical fetal gender identification for you. But in Hong Kong, it is recognized by law to do fetal sex identification. Generally, the gender of the fetus can be identified by B-ultrasound at the time of four months of pregnancy. Next, let me introduce several common detection methods.

Reliable detection? You can see boys and girls for months

First, amniocentesis: there are many ways to identify the gender of men and women after pregnancy, and amniocentesis is one of them. At about 16 weeks of pregnancy, amniocentesis was performed and amniotic fluid was extracted for special culture. After examination, if the sex chromosomes were XX, the fetus was female; if the sex chromosomes were XY, the fetus was male.

Second, B-mode ultrasound diagnosis: B-mode ultrasound diagnosis, not only can check out the sex of the fetus, but also can see whether the fetus has microcephaly, meningocele, hydrocephalus and other serious mental development disorders, at the same time can also check out whether twins, hydatidiform mole and ectopic pregnancy. This is not only a kind of damage to the fetus and pregnant women, but also a high accuracy examination method.

Third, the detection of X or Y sex chromosomes of chorionic cells can also early predict fetal sex, with an accuracy of more than 90%. When the external genitalia of the fetus can be distinguished, the sex of the fetus can also be judged by direct observation with a fetoscope.
