The blood pressure of women before conception can determine the sex of the fetus

The story of blood pressure related to the control of the sex of the fetus is currently a problem that is surprising to the medical community.

Accordingly, scientists at Mount Sinai Hospital in Toronto have announced that pre-conception women's blood pressure is related to determining the sex of the fetus, specifically the study of the previous women. When conception has low blood pressure, it is common to give birth to girls , whereas those with high blood pressure often give birth to boys .

' The blood pressure factor that governs the sex of the fetus is a medical phenomenon that is difficult to recognize normally ' - Dr. Ravi Retnakaran said in a statement.

' This new finding will be an important scientific basis for implementing family planning measures, population balance, and male-female ratio in society' - Ravi Retnakaran added.

To reach this conclusion, the research team conducted a survey of 1411 women in Liuyang Province, China. And especially this survey team is planning to become pregnant.

Monitoring blood pressure of this group of women during long periods before and after conception combined with age factors, cholesterol levels . The results showed that 739 boys and 672 girls were born .

Surprisingly, mothers with low systolic blood pressure about 103.3mmHg are most likely to give birth to girls. In contrast, people with high blood pressure of about 106mmHg are mostly male. The difference in blood pressure between the two subjects is 2.7 mmHg.

In terms of percentages, the range is about 50/50, with the advantage of studying male gender a bit. And with the rate of blood pressure difference of 2.7 mmHg, although the rate is very small, but it has produced a clear result, the number of sexes of children is very important in balancing gender in the commune.

In 2009, a similarly interesting finding showed that the more married couples live in the equator, the easier it is to give birth to girls .
