Baby Gender is a program that allows you to predict the gender of the baby of your pregnant friends based on their birth dates.
Baby Gender is based on the biological rhythms of the babys parents. This method tries to identify which chromosomes are stronger at the time of conception, the males or the females, based on the birth date of the parents.
This calculation is based on decades of nursery personnel experience and is not a scientifically based or proved procedure. Other factors that influence the gender of the baby are well known and cannot be controlled using this method so this wont be a 100% prediction.
Based on an ample test group, the approximate effectiveness of this method is around 78% and it is only applicable to natural conceiving. To test the accuracy of this method you could use data of already born children or even yourself using the birth date of your parents.
Always remember that no method could give you a 100% certainty, but for sure this is a fun way to amaze your pregnant friends with how accurate your predictions are.
