After the pregnancy, many people will be pregnant mothers based on the various manifestations to speculate on the pregnancy is a boy or a girl, although it is said that the child's gender from the fertilization of the egg from the beginning of the already determined, but also can not stop people biased towards their own desired gender results of the imagination.

So, by the twelfth week of pregnancy, the different sex of the fetus in the womb, whether there will really be any difference in performance?

One, the gender characteristics of the manifestation is to wait until 16 weeks

B ultrasound examination is able to determine the baby's gender through the ultrasound imaging, want to clearly see the baby in the end is a boy or a girl, it will need to wait until 16 weeks of the fetus's reproductive organs to develop and shape, only to be able to determine the determination of ultrasound examination through the ultrasound. Therefore, in 12 weeks of pregnancy, through the ultrasound can not see anything.

And to see clearly whether the baby is a boy or a girl, it requires the baby? cooperation? Only then can the baby's reproductive organs be seen when the body is positioned correctly during the ultrasound and the limbs are not covered, as a way of determining the sex characteristics of the baby.

However, there are clear regulations in China, hospitals can not do gender identification through ultrasound, and even more so, can not disclose the baby's gender information to the pregnant woman, so go to the hospital to do ultrasound, the doctor can see and will not tell you.

Second, look at the shape of the gestational sac is not different

This is actually just a probability, that is to say, when the gestational sac favors a certain shape, the probability of a single gender will be greater. And by the 12th week of pregnancy, ultrasound can already clearly see the gestational sac in the abdomen and can accurately detect the exact size of the sac size.

Generally speaking, if the overall shape of the gestational sac appears to be an oval, then the fetus is likely to be more of a girl, and if the shape of the sac is an irregular long eggplant shape, then the fetus is likely to be more of a boy. But this is not guaranteed to be 100% accurate.

Three, look at the pregnant mother's reaction to the different

In the early stages of pregnancy, most of the mothers need to go through a long and painful reaction to the pregnancy, so some people will be based on the mother of the intense degree of vomiting to see whether it's a boy or a girl, and the conclusion is that: the reaction to the strong vomiting is a boy, the reaction to the vomit is not very strong is a girl.

But in fact, there is no connection between pregnancy vomiting and the sex of the fetus, the vomiting may be due to the mother's physical fitness is not good enough, as well as the body's estrogen and progesterone secretion levels are different, so there is no connection with the baby's sex.

Four, look at the different taste preferences of pregnant mothers

There is an old Chinese saying that has been around for a long time? "Sour children, spicy women? It is also from the pregnant mothers after pregnancy taste changes to determine the sex of the baby is different, if the mother likes to eat more sour taste, then it is likely to be a boy, and vice versa if it is spicy, then it is likely to be a girl. In fact, there is no necessary connection, but also a kind of statistical probability of big data.

Fifth, the direct chromosomal differences

The sex of the fetus is determined at the beginning, so the biggest difference between the different sexes of the fetus lies in the chromosomal differences, the boy's chromosome combination is YX, while the girl's is XX, then, in the DAN examination, we will be able to clearly see this difference.

Important note: Although mothers want to know the sex of the fetus after pregnancy, but to determine the sex through ultrasound, you need to wait until 16 weeks, and the hospital doctors will not be explicitly informed, and other things, such as the shape of the gestational sac, the reaction to vomiting and taste preferences on the difference, is only a probability of the problem, the accuracy is not high.

Lastly, I'd like to say that it's the same for both boys and girls, as long as they grow up in the care of their parents, they will be the ones to rely on and support them when they grow up!
