Usually the earliest point you can tell the sex of a baby from a scan is 20 weeks, but like the Ramzi Theory , this quirky theory says you can tell the sex of your baby at your very first ultrasound. The Nub Theory is based on the hypothesis that you can predict the sex of your baby based on the angle of their genital tubercle. According to this theory, the angle of the nub will indicate whether a baby is a boy or girl. The nub is at a much steeper angle upwards from the spine, indicating that this could be a baby boy. That includes not having their legs closed! Keep in mind, the sonographer may not have extra time between appointments to wait for the baby to move into a better position to make a prediction.
