The NT examination report cannot determine the gender of the fetus. NT is a screening for the transparent layer of the fetal neck, which is the earliest examination to exclude whether the fetus has congenital neural tube defects.

1. NT examination cannot determine the gender of the fetus

The NT examination report cannot determine the gender of the fetus. NT examination is a transparency check of the fetal neck, commonly used for prenatal screening, which can diagnose chromosomal diseases and detect fetal abnormalities caused by various reasons in the early stage. If it exceeds 3mm, it often suggests poor fetal outcomes, and generally B-ultrasound examination is used. Although NT examination uses B-ultrasound to observe the condition of the fetus, the focus of NT examination is on observing the thickness of the transparent band behind the neck. To determine the gender of the fetus, a doctor needs to use an ultrasonic instrument to observe the fetus's reproductive organs. Therefore, it is impossible to determine the gender of the fetus only through NT examination.

2. The role of NT examination

Routine obstetric B-ultrasound examination mainly focuses on the development and general structure of the fetus. With the development and popularization of transvaginal ultrasound, more attention is paid to the proportional relationship between various tissue structures of the fetus. Quantitative analysis and detection indicators are used to predict whether the fetus has certain defects, especially chromosomal abnormalities. For example, the measurement of the transparent layer of the fetal neck is becoming one of the effective methods for prenatal screening of fetal chromosomal abnormalities.

3. Time for identifying the gender of the fetus

During pregnancy, gender determination through B-ultrasound is distinguished based on the reproductive organs, but the results must be accurate after the 15th week of pregnancy. This is because there are significant differences in the reproductive organs of male and female fetuses after the 15th week of pregnancy, which can be clearly seen.
