Want to know if you'll have a boy or a girl? This surprising research suggests there might be a way to get a better idea before you've even conceived.
Ever wonder why some women seem to give birth to only boys while others have families full of girls? According to new research, an unexpected factor—a woman's blood pressure—might have an effect on whether she has a boy or a girl. The crazy part? The study's authors claim this effect comes into play before a woman has even conceived. So you may be able to get a better picture of whether you'll be a boy mom or a girl mom before you're even pregnant.
The study, which was published in the American Journal of Hypertension, was based on the observation of a group of women who were planning to get pregnant. The researchers assessed the participants before they conceived and through gestation until they delivered. The researchers observed the births of 739 boys and 672 girls.
The researchers found a relationship between systolic blood pressure and the sex of the babies these women welcomed. According to their research, women with higher systolic blood pressure appeared to be more likely to give birth to boys, while lower blood pressure seemed to correlate with giving birth to 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, M.D., said, according to ScienceMag. "This novel insight may hold implications for both reproductive planning and our understanding of the fundamental mechanisms underlying the sex ratio in humans."
But let's not forget that this study doesn't necessarily establish cause and effect—the findings could very well be pure coincidence. So while we've all understood that genetic information from the man dictates a baby's sex, the mother's health could come into play. So if you'd like to prognosticate about what you can expect long before that 20-week ultrasound, this might just help you guess smarter.
