Study: Child's Gender Is Not Always Random

A new study published in Nature suggests that a child's gender at birth is not always random. The mother's age and genetics can play a significant role.

The study, which examined maternal and genetic factors influencing offspring gender, found that in families with three boys, there is a 61% chance the next child will be a boy. Similarly, in families with three girls, there is a 58% chance the next child will be a girl.

Alex Polyakov, an obstetrician and researcher at the University of Melbourne, emphasizes that the findings challenge the notion that there is an equal chance of having a boy or a girl in each pregnancy.

Researchers at Harvard University in Boston analyzed data from 58,007 female nurses in the United States between 1956 and 2015. They found that women aged 29 and over when they had their first child were 13% more likely to give birth to children of only one gender.

The researchers note that changes in vaginal pH with age could affect the child's gender.
