Fetal Sex Determination by USG

Fetal gender assignment by first-trimester ultrasound.
"Ultrasound determination of fetal sex can benefit decision-making regarding invasive prenatal testing in pregnancies at risk of sex-linked genetic abnormalities.
The genital region was examined in the mid-sagittal plane by the authors. The angle of the genital tubercle to a horizontal line through the lumbosacral skin surface was measured. The fetus was assigned male gender if the angle was greater than 30 degrees , and female gender if the genital tubercle was parallel or convergent less than 1o degrees to the horizontal line. At an intermediate angle of 10-30 degrees the gender was not determined. Prenatal gender assignment by ultrasound has a high accuracy rate at 12-14 weeks. "
