How accurate a baby gender predictor is a 3D or 4D ultrasound?
A 3D or 4D ultrasound is slightly better at determining baby gender than a standard 2D ultrasound. Particularly for identifying the presence of a boy, the solidification of the image makes the forms of the scrotum and penis more prominent. The three lines indicator that your baby will be a girl is stronger in a normal 2D ultrasound, however, as most modern multidimensional ultrasound systems have the ability to change to 2D imagery, a 3D or 4D scan always has an advantage. The 3D or 4D ultrasounds may therefore ‘fill the gap’ by providing a better option of identifying baby gender before 16 weeks. Bear in mind, however, that it is still not full-proof baby gender predictor. Factors such as the baby position, placenta position and possible umbilical cord obstruction all play their part. If genital regions are visible then the accuracy of gender predictions are above 90% at after 16 weeks. Your health care provider will often refrain from giving a conclusive diagnosis of baby gender unti
