Mother’s blood pressure can influence the sex of her children

This study conducted by scientists in Canada came to show that women with higher blood pressure are more likely to give birth to a boy, while women with lower blood pressure, a girl.

The study, conducted by Canadian scientists, has shown that a woman’s blood pressure, about 26 weeks before she becomes pregnant, can greatly influence the sex of her children, meaning higher blood pressure signals mean that she is more likely to give Light a boy – if they are lower, a girl, The Telegraph reported.

“This suggests that a woman’s blood pressure before pregnancy is a previously unrecognizable factor that is associated with the likelihood of having a boy or a girl”, said Dr. Ravi Retnakaram, an endocrinologist at Mount Sinai Hospital in Toronto.

This finding was made by chance, at a time when researchers were trying to find out what the determinants for the ratio of male and female infants in a given population were, coming to this question to the conclusion that stress environments are the big (for example wars, natural disasters and even economic crises). That is, in times of increased stress, one gender is more likely to survive relative to another during pregnancy.

Thus, according to Ravi Retnakaram’s explanation, “When a woman is pregnant, the sex of the fetus is determined by the fact that the father’s sperm supply an X or Y chromosome, and there is no evidence that this probability is variable in humans. However, what is believed to vary is the ratio between male and female fetuses, which ends up being lost during pregnancy”, added Retnakaram in testimony to The Telegraph.

Simply put, women who have lower stress, have a physiology less conducive to the survival of a male fetus and women with higher stress, are less conducive to the survival of a female fetus.

This study published in the American Journal of Hypertension also counted on the participation of 1,411 Chinese newlyweds who were trying to get pregnant, so their arterial tensions were measured about 26 weeks before they became pregnant and were followed throughout the process. In the end, the women gave birth to 739 boys and 672 girls.
