New study: stressed women are more likely to give birth to a girl

A new research made in New-York have shown that pregnant women who suffer from high levels of stress are at more risk of miscarrying a baby if the baby is a boy. The results have been published in the journal of the Proceedings of the National Academy of Sciences. The results of this research explain the increase in birth of girls following national traumas such as terror attacks, earthquakes or wars.


Scientists at Columbia University studied 187 pregnant women. They observed women and checked the levels of psychosocial, physical and lifestyle stress. Group of researchers found out that the boy-to-girl ratio in women who were physically stressed was 4:9, and 2:3 in women who were psychologically stressed.

Scientists say that these results might be explained by the fact that males need more time to complete their early developmental stages, leaving them more vulnerable to sub-optimal conditions in the womb.


Professor Monk, who conducted the study, said that women who feel “overwhelmed” for a long period of time during early pregnancy stages are at more risk, as well as those who suffer from mild depression.

This study also supports other studies in this field, that showed that stress in animals also affects their offspring.
