While many expectant fathers and expectant mothers are happy about the arrival of their baby, they are also curious about the gender of the baby, because hospitals cannot perform gender tests on babies. Therefore, many people use some methods and symptoms to verify whether the baby is a boy or a girl. There are also some pregnant mothers who ask acquaintances to do NT at 12 weeks. So what are the characteristics of boys who do NT at 12 weeks?

NT is mainly an examination to check whether the development of the fetus is normal and healthy, and whether there will be malformations. Generally, it cannot check whether the fetus is a boy or a girl. If you do nt at 12 weeks, you can't actually know the gender of your baby. Although the gender of the fetus in this cycle has been determined, it cannot be clearly seen because the reproductive organs are not fully developed and are in the growth stage. However, some experienced doctors can make a simple judgment through some of their own judgments combined with NT. If NT is said to be a boy, it is mainly based on these two points, NT value and NT chart.

By the 18th week of pregnancy, the result of judging the gender of the fetus is relatively accurate, and the accuracy rate is relatively high. It is normal for the nt value to be below 3mm. Under normal circumstances, if the nt value is greater than 1.5mm and less than 3mm, the possibility of conceiving a boy is relatively high. If the NT diagram is so swollen that the fetal spine line and buttocks form an acute triangle of about 30 degrees, with the buttocks and legs pointing upward, the fetus with this shape is generally a boy.

But in fact, the above statement has no scientific basis, so you don’t need to take it too seriously. In fact, regardless of whether you are pregnant with a boy or a girl, since you are pregnant, a healthy, safe and smooth birth of the baby is the best gift God has given to this family.
