The time when the gender of the fetus becomes apparent
How many months into pregnancy can you tell the gender of your baby through B-ultrasound? This is a question that many expectant mothers are very concerned about. Generally speaking, the gender characteristics of the fetus can be checked through multiple B-ultrasound examinations before birth. Specifically, an ultrasound examination performed around 12 weeks of pregnancy can initially determine the gender of the fetus, while a B-ultrasound examination performed around 20 weeks of pregnancy is the most accurate time to determine the gender of the fetus.
B-ultrasound characteristics of male and female fetuses
B-ultrasound examination mainly determines the gender of the fetus by observing its genital development. Generally speaking, the genital development of boys is more obvious, and the shape of the penis can be observed on the B-ultrasound at about 12 weeks of pregnancy. This feature is an important sign for judging whether the fetus is male or female. The development of girls\’ genitals is relatively obscure. It is necessary to carefully observe the shape and size of the vagina and clitoris on a B-ultrasound at about 20 weeks of pregnancy to determine the gender.
Factors affecting judgment accuracy
Although B-ultrasound examination is currently one of the most accurate methods to determine the gender of the fetus, there is also a certain probability of misjudgment. This is mainly due to fetal development characteristics and technological limitations. For example, because the fetus\’s genitals are not fully mature in the early stages of development, sometimes the characteristics of the genitals of male and female fetuses are not very obvious, and the differences in location and angle during examination will affect the accuracy of judgment. Therefore, you should maintain an objective attitude towards the results of B-ultrasound examination. Especially if you want to get more accurate results, you can reexamine multiple times, or consider other methods to determine the gender of the fetus.
Other checking methods
If the B-ultrasound examination results are unsatisfactory or you want to know the gender of the fetus more accurately, in addition to B-ultrasound examination, you can also consider other examination methods. For example, during amniocentesis after 16 weeks of pregnancy, fetal cells can be obtained for chromosomal analysis to determine the gender of the fetus. However, amniocentesis examination has certain limitations and risks, and expectant mothers need to choose carefully after signing their consent. In addition, there are currently businesses selling fetal gender testers and pregnancy test sticks, but their accuracy is controversial and should be carefully considered.
Summary
It is a common method to determine the gender of the fetus through B-ultrasound examination, but the British National Institute of Health recommends that B-ultrasound examinations performed before 20 weeks of pregnancy, especially around 12 weeks, should not be based solely on reading the numerical results. , it is best to synchronize the inspection results and corresponding diagnostic standards with further testing to ensure the accuracy of the results. If expectant mothers want to know more accurately about the gender of their fetus, they should choose an appropriate examination method based on their own situation and conduct it under the guidance of a doctor and examination center.
