What is the likelihood of having a boy with NT 1.2 mm?

Under normal circumstances, there is no significant probability associated with an NT measurement of 1.2 mm. The normal range for NT values is less than 2.5 mm; therefore, an NT of 1.2 mm falls within the normal range, indicating that there are no chromosomal abnormalities in the fetus or associated cardiac malformations. The detailed explanation is as follows:

NT screening is a very important examination that uses ultrasound to measure the thickness of the nuchal translucency in the fetus to assess the risk of Down syndrome. The normal value for NT should be less than 2.5 mm. Generally, the higher the NT value, the greater the likelihood of fetal abnormalities. An NT measurement of 1.2 mm is considered normal. However, clinically, this value has no direct correlation with the baby's gender or other birth outcomes. NT screening is merely the first step during early pregnancy to rule out fetal abnormalities, and the final NT measurement serves as a key criterion in assessing whether fetal malformations are present.

In summary, NT screening is simply one method used to evaluate fetal health and is not related to predicting specific birth outcomes. If abnormal results occur, it is essential to take them seriously and promptly seek further evaluation at a reputable medical facility.
