Background: The improvement of high-resolution ultrasound equipment has provided the possibility of determination of the fetal gender during pregnancy. However, because of the way in which the genitalia develop, the accuracy of gender identification is different among gestational age.
Objective: To assess the accuracy fetal gender determination during prenatal screening and to find in which week of the gestational age is more accurate.
Methods: A questionnaire had been distributed to a group of sonographers working in king Abdulaziz University, Jeddah and Khobar hospitals .another questionnaire prepared for a group of women who delivered their babies in those hospitals. Data collected, analyzed by using Microsoft Excel software.
Result: 13 (76%) of the responses indicated that fetal gender determination by ultrasound has a high precision in second trimester (13-27 weeks of gestational age), while the remaining 4(24%) found the gender can identified in the first trimester.
Of the of the total 52 women with ultrasound scan, 50 (96%) knew about the fetal gender during the pregnancy, while only two (4%) answered by no. 46 (92%) of women the gender was the same as determined by ultrasound, while only 4(8%) of women was not. The overall accuracy to correctly determine the fetal gender was 92%.
Conclusion: From this research work we can conclude that prenatal gender assignment by ultrasound has a high degree of accuracy rate at 14 to 21 weeks.
