title: Determination of foetal sex by ultrasound: state of the art.
abstract: The determination of foetal gender is clinically indicated in sex-linked disorders. The reliability of ultrasound in prediction during the late second and third trimesters is well-established. Few studies attained high success rate in early second trimester. The variations in the success rate are due to the difference in size and gestational age of the published samples. Most studies have concentrated on the visualization of the external genitalia. Differentiation based on internal organs is not pursued. The ethical aspects have received attention by almost all workers in this field.
