Technology has advanced the humanity into a world of convenience. It's also true in the medical world. Pregnant women can now know their baby's gender as early as 16 weeks in gestation. However, a controversial yet striking study says, aspiring moms may now be informed of their offspring's gender even before it's conceived.
How is this possible?
Scientists in Canada say, by checking a woman's blood pressure 26 weeks before pregnancy, they can identify the baby's sex. Experts claim, higher systolic blood pressure signals she will deliver a boy while lower suggests a girl.
Dr. Ravi Retnakaran, endocrinologist at Mount Sinai Hospital in Toronto, told the Telegraph
, “It suggests that a woman's blood pressure before pregnancy is a previously unrecognised factor that is associated with her likelihood of delivering a boy or a girl.”
In the study
, experts recruited 1,411 newly-married Chinese women, and took their blood pressure.
The results showed, women who had boys was 106 mm Hg, and for those who had girls was 103 mm Hg before conception. Researchers also learned that overall the women gave birth to 739 boys and 672 girls.
“This study suggests that either lower blood pressure is indicative of a mother’s physiology that is less conducive to survival of a male foetus or that higher blood pressure before pregnancy is less conducive to survival of a female foetus," Dr Retnakaran said.
In pregnancy, the gender of the fetus depends on whether the father provides an X or Y chromosome sperm. Though, the conception sex ratio remains at 50:50, the birth ratio will alter depending on which sex is stronger.
Fertility expert Prof Charles Kingsland, of Liverpool Women’s Hospital, told the Telegraph, “We have been aware that more male fetuses miscarry than females and more females are born for obvious biological reasons, namely you need more women in the world to have children.
“There is also some evidence that you are more likely to miscarry a boy when you are compromised either by health or environmental issues. So I suppose, blood pressure changes in these circumstances might affect conception of different sexes."
Does this mean, tailoring your baby's gender is purposely putting yourself in stressful events? Hmm..no thanks.
