31 gru 2015 · After 13 weeks, success rates for correctly predicting males exceeded that of female fetuses. Statistical differences were noted in the success rates of individual sonographers. Sixty seven percent of women were in favour of knowing fetal gender from ultrasound.

21 lut 2006 · The accuracy of female assignment increased with increasing CRL: it was 91.5% at a CRL of 55.4 to 62.5 mm (12 to 12 + 3 weeks); 99% at a CRL of 62.6 to 67.9 mm (12 + 4 to 12 + 6 weeks), and 100% at a CRL of 68.0 to 83.9 mm (13 to 13 + 6 weeks).
31 gru 2010 · This study demonstrated that the gestational age of the fetus has a material effect on the accuracy rate of gender determination. At 12 weeks and over, the average success rate for correctly identifying gender, where gender identification was possible, was 94.8%, with the accuracy at 13 weeks of 98.3% approaching that achieved by invasive testing.
Understanding Gender Accuracy Rates: While expectations for 100% gender accuracy in a 13-week ultrasound may be unrealistic, studies have shown encouraging results. On average, the accuracy rate falls within a range of 85% to 95%, depending on various factors.
3 maj 2023 · The results were divided into three categories based on gestational age: 11 + 2 to 12 + 1, 12 + 2 to 13 + 1, and 13 + 2 to 14 + 1 weeks’ gestation. To establish its accuracy, the first trimester fetal sex determination was compared to fetal sex determined on a mid-second trimester ultrasound.
Conclusion Prenatal gender assignment by ultrasound has a high accuracy rate at 12–14 weeks. These results indicate that invasive testing can probably be carried out in fetuses identified as males at this gestational age.
Gender can be detected with great accuracy in gestations between 11 to 13 weeks and 6 days by using AGD. CRL and gestational week (GW) were determined as nonsignificant predictors of fetal gender by AGD measurement.
