Objectives : The purpose of this study was to determine the accuracy of sonographer predictions of fetal gender during routine ultrasounds. Primarily, the study sought to investigate the accuracy of predictions made in the first trimester, as requests from parents wanting to know the gender of their fetus at this early scan are becoming increasingly common.

Second and third trimester fetuses were included in the study to confirm the accuracy of later predictions. In addition, the mother’s decision to know the gender was recorded to determine the prevalence of women wanting prenatal predictions. Methods : A prospective, cross sectional study was conducted in a specialist private obstetric practice in the Illawarra, NSW.

A total of fetuses across three trimesters were examined collectively by seven sonographers. Fetal gender was predicted using the sagittal plane only in the first trimester and either the sagittal or transverse plane in later trimesters. Phenotypic gender confirmation was obtained from hospital records or direct telephone contact with women postnatally. Male fetuses under 13 weeks were more likely to have gender incorrectly or unable to be assigned.

After 13 weeks, success rates for correctly predicting males exceeded that of female fetuses.

In short, the researchers found that there were no meaningful differences between the prediction of date of birth by scan and last menstrual period LMP.

Which means, they conclude, that if the woman feels her own menstrual dates are reliable, there is no need for an early dating scan. This is good news for a couple of reasons. In a retrospective study, data were analyzed from 18 women with spontaneous labor who delivered a single neonate without major anomalies in a local health district in Australia between and Data were sourced from a computerized population birth database.
