What is the Ramzi method to know the sex of the baby?

By Silvia Azaña Gutiérrez B.Sc., M.Sc. (embryologist).
Last Update: 04/04/2023

The Ramzi method is a method that can be used to predict by ultrasound, as early as 6-8 weeks of pregnancy, the sex of the baby.

This method is based on the position of the placenta within the uterus, which, because of the polarity of the chromosomes, is to the right if it is a boy or to the left if it is a girl.

However, this method is not sufficiently accepted and it is usual to wait for the ultrasound scan in the 20th week of pregnancy to know the sex of the baby with great precision and probability of success.
