Abstract

© 2014 SEGO. Objective: To assess the accuracy of fetal gender determination by ultrasound at 11-14 weeks' gestation as part of first-trimester ultrasound screening. Material and methods: Fetal gender assessment by ultrasound was prospectively carried out in 534 women at 11-14 weeks of gestation attending first-trimester ultrasound screening. The genital region was examined in a midsagittal plane to determinate the direction of the genital tubercle to a horizontal line through the lumbosacral skin surface. Fetal gender was assigned as male if the angle was greater than 30 degrees and as female if the tubercle was parallel or convergent (less than 30 degrees). Clinical confirmation of fetal gender was obtained by 20- and 32-week ultrasound and after delivery. Results: Fetal gender was correctly determined in 85.13% of cases. The accuracy of sex assignment was 78.32% at 11 weeks, 84.49% at 12 weeks, and 93.7% at 13 weeks. Gender was correctly determined in 82.8% of the male fetuses and in 88% of the female fetuses. Conclusion: Fetal gender can be determined with an acceptable efficiency at 12-14 weeks of gestation on routine ultrasound.
