How accurate is an ultrasound for gender?
The results of this study indicate ultrasound gender predictions by sonographers are 100% sensitive for accurately predicting the gender in the second and third trimesters. The overall success rate of correctly identifying fetal gender in the first trimester was much lower (75%).
