If you’ve ever wondered what the sex of your baby is likely to be, a study has revealed it could be as easy as examining your blood pressure.
According to a study published in the American Journal of Hypertension, women with higher systolic blood pressure are more likely to give birth to boys. While those with lower blood pressure are more likely to give birth to girls.
Researchers revealed this effect comes into play even before a woman has conceived. They study looked at the births of 739 boys and 672 girls.
“(This research) suggests that a woman’s blood pressure before pregnancy is a previously unrecognized factor that is associated with her likelihood of delivering a boy or a girl,” study author Ravi Retnakaran told Science Magazine.
“This novel insight may hold implications for both reproductive planning and our understanding of the fundamental mechanisms underlying the sex ratio in humans.”
While some have argued the findings could be coincidental, it could help explain why some women tend to only give birth to boys, while others have huge families of girls.
