Knowing the gender of a baby seems to be one of the awaited events of a pregnancy. And because of this, there has been quite a number of so-called “ways” of trying to determine the gender of the baby that are largely unproven scientifically. These are wives’ tales that try to predict if a baby will be a boy or a girl while still in the womb. A recent study published in China may have found a possible way to do just that. It indicates that a mother’s blood pressure before conception may be a factor in determining a child’s gender.
Extensive research on farm animals have been trying to find out how to predict their offspring. One theory states that female cows, as well as other animals, that are in better physical condition are more likely to produce male offspring. Scientists argue that this may also apply to humans. A large study aims to sought out this connection and find a link between a female’s physical condition and predicting the gender of an unborn child.
Researchers, along with Dr. Ravi Retnakaran, an endocrinologist at Mount Sinai Hospital in Toronto, Canada, and an investigator with the Lunendfeld-Tanenbaum Research Institute, conducted a study starting in 2009 that involved 1,411 female participants from Liuyang in China. The participants had their health conditions assessed, taking measurements of their blood pressure, cholesterol, glucose and triglyceride levels. The measurements were taken at an average of 26.3 weeks before the participants became pregnant. Overall, the pregnancies resulted in the birth of 739 baby boys and 672 baby girls.
Analysis of the data taken from the participants showed that the mean adjusted systolic blood pressure prior to conception was found to be higher in women who eventually gave birth to male babies. Even while the researchers adjusted for other factors such as age, smoking, body mass index, and others, the difference was still significant the women who gave birth to a boy had a mean systolic blood pressure of 106.0 millimeters while those who gave birth to baby girls had a mean systolic blood pressure of 103.3 millimeters.
According to Dr. Retnakaran, the findings “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. This novel insight may hold implications for both reproductive planning and our understanding of the fundamental mechanisms underlying the sex ratio in humans.”
Further studies may be needed in order to determine if the connection between blood pressure and a baby’s gender may be genuine. Findings of the said study was published in the American Journal of Hypertension.
