Researchers have found a groundbreaking way to control the sex of the baby through maternal blood pressure before pregnancy. The new study, led by Dr. Ravi Retnakaran from Mount Sinai Hospital in Toronto, Canada, stated that the finding has significant importance as it deals with questions about selecting the baby's sex. A lot of parents are inclined to choose their child's gender nowadays, and this new study, if replicated successfully can provide the cheapest and easiest way to do it. 

Dr. Ravi Retnakaran, an endocrinologist, started recruiting for subjects in 2009. A total of 1,411 women who were planning to get pregnant were selected as participants for the study from Liuyang in China. They all underwent physical and medical examinations at the start and during pregnancy with their blood pressure, cholesterol, triglycerides, and glucose measured at average of 26.3 weeks before conception, the News reports. 

All in all, 739 baby boys, and 672 baby girls were delivered in the experiment.The researchers found that systolic blood pressure before pregnancy was higher in women who gave birth to boys at 106.0 millimeters of mercury, and lower in those who had girls with103.3 millimeters of mercury. In conclusion, the study found that those with the lowest reading, there is a 43 percent chance of having a boy, while those with the highest had a 62 percent chance, the Medical News Today says. 

The scientists explain that a higher maternal blood pressure before pregnancy indeed came out as a valuable factor in delivering a boy. The implication of this finding indicates that would be parents can now have a possibly reliable way in detecting their baby's gender, and even attempt to manipulate it through blood pressure before conceiving. With a number of other useful pregnancy-related news this week, using maternal blood pressure to control an offspring's gender certainly seems groundbreaking.
