Single Mothers Have More Girls Than Boys, Study Reveals
Does the fact if the mother is single or married determine the sex of the baby? Well, it appears that it does, according to a scientific study that confirms the biological theory that the sex of a baby is determined by the family conditions.

The study done by the University of Boston of 86.000 births between 1959 and 1998, shows that single mothers more baby girls than boys.

According to the data, when the father lives with the future mother, there is a 14% higher chance of the baby being a boy.

The investigation shows that women who do not maintain a stable and monogamous relationship tend to have less boys, leading investigators to conclude that single mothers have more baby girls.
