Which factors determine the gender of the future child?

People shake the dice cup harder when they need a high number. They believe in winning the lottery if they tick their own numbers. And they swear by certain positions, moon phases or ambient temperatures in order to beget a boy or a girl. Is it all just unreal?

First of all, the chance of finding the desired sex is not bad. While the chances of winning the lottery jackpot are much lower than dying the following day, the chances of having the desired child are a comfortable 50:50. This good starting position explains why so many people seem to be successful in their arrangements for having their desired child.

In addition, the gender of the child does not seem to be left to pure chance if you look at what scientists have found out: Girls are born more often when there is bad weather, crises, wars or hunger. Warm weather and good economic conditions, on the other hand, increase the chance of a boy.

A current study confirms these findings. US researchers evaluated the births during the great famine in China from 1959 to 1961. As the population suffered, more girls were born.

As early as 2008, British scientists had established a connection between the nutritional status of women and the gender of their child: women who had a high-energy and high-sugar diet at the time of conception had a higher than average frequency of boys. Especially the women who preferred muesli in the morning gave birth to sons a little more often.

These observations support the previous investigations: The diet at the time of conception depends on the weather and the economic conditions within the women's environment. And it is likely an indicator of the woman's energy reserves and state of health.
