Binary classification tests for the ultrasound identification of male and female genders.

A study conducted by Hsiao et al. Since, in the present study, ultrasound imaging was performed in the 11 th and 12 th weeks of pregnancy, the overall accuracy obtained was very favorable Ultrasound accuracy was Compared to Hsiao's study, the ultrasound identification accuracy obtained in the present study was significantly higher in the 11 th week of pregnancy. In , Whitlow and Efrat published the very first articles about fetal gender identification in the first trimester of pregnancy.
The results obtained by Whitlow et al.

Ultrasounds may reveal sex organs by 14 weeks, but they aren't considered fully accurate until 18 weeks. If you have CVS at 10 weeks, the results will reveal your baby's sex by 12 weeks.
