Is NT less than 1.5 necessarily a girl? How can we accurately confirm the gender of the fetus? NT less than 1.5 refers to the thickness of the fetal neck transparent layer being less than 1.5 millimeters, which is an early prenatal screening indicator. Many people believe that NT less than 1.5 is necessarily a girl, is this really the case? Next, we will delve deeper into the following aspects.

What is NT?

The full name of NT is Nuchal Translucency, which means "neck transparent layer" in Chinese, referring to a transparent liquid layer behind the fetal neck. NT thickness is one of the indicators for prenatal screening of congenital heart disease, which can be measured through ultrasound examination.

Is NT less than 1.5 a girl?

The fact is not that, NT less than 1.5 cannot determine the gender of the fetus. NT less than 1.5 only indicates that the likelihood of fetal chromosomal abnormalities is low, but it does not necessarily mean that the fetus is healthy or a girl.

According to a large amount of data research at home and abroad, the relationship between NT size and fetal gender is not significant, as NT size is influenced by multiple factors such as gestational age, maternal age, maternal BMI, etc., while fetal gender is mainly determined by sperm fertilized eggs, and there is no necessary connection between the two.

How to accurately confirm the gender of the fetus?

Prenatal echo examination is currently one of the most commonly used and accurate methods for confirming fetal gender. Prenatal echo examination can be performed around 20 weeks of pregnancy by detecting the reproductive organs of the fetus using an ultrasound probe to determine the gender of the fetus.

In addition, pregnant women can also choose methods such as DNA double testing or amniocentesis to accurately confirm fetal gender, but these methods require invasive procedures, have certain risks, and require high costs.

The meaning of NT less than 1.5

Although the size of NT is not necessarily related to fetal gender, the possibility of fetal chromosomal abnormalities can be ruled out when NT is less than 1.5, making it an important prenatal screening indicator.

The relationship between NT less than 1.5 and chromosomal abnormalities is as follows:

1. The correlation between NT less than 1.5 millimeters and certain chromosomal abnormalities (mainly trisomy 21) is low, but not completely unrelated.

There is a significant correlation between NT greater than 3.5 millimeters and chromosomal abnormalities.

When the NT is less than 1.5 millimeters, the risk of chromosomal abnormalities is very low, but comprehensive evaluation still needs to be combined with other indicators.

Therefore, although NT less than 1.5 cannot determine the gender of the fetus, it still has certain significance and can provide important prenatal screening information for pregnant women.

Is NT less than 1.5 necessarily a girl? How can we accurately confirm the gender of the fetus? NT less than 1.5 does not mean that the fetus is a girl, and the possibility of the fetus suffering from other diseases cannot be ruled out. NT less than 1.5 only indicates a lower risk of fetal chromosomal abnormalities and is an important prenatal screening indicator. If you want to accurately confirm the gender of the fetus, it is recommended to choose prenatal echo examination and choose other screening methods based on the actual situation after consulting a doctor to comprehensively understand the health status of the fetus.
