Expectant mothers will find the words X and Y on the list issued by some hospitals when they get nt report forms. Some people will interpret it as an indication of the sex of the fetus, and some hospitals will write M or F, that is, male and female. In fact, it is just a piece of information on the report, which doctors use to judge the situation of the report.
There is no direct information about the sex of the fetus in nt report. The results of nt report are used to evaluate the risk of Down syndrome in early fetus. Abnormal nt results can find out whether the fetus has heart malformation and achondroplasia in time. It is more necessary to judge the sex of the fetus by nt color Doppler ultrasound, but the position related to the sex of the fetus will not be displayed in color Doppler ultrasound, and it needs to be judged by the real-time picture of the detector during inspection.
The Nt report pays more attention to examining the health status of the fetus, rather than paying attention to whether the fetus is male or female, and the state does not advocate hospitals to disclose the sex of the fetus, just to avoid the phenomenon of son preference.
