Why do you only give birth to girls and not boys when the cadmium content in drinking water is particularly high?

In Gaoban Village, Qingliu County, Fujian Province, China, there used to be 10 households with 49 people, including 20 males and 29 females. They moved in during the construction of Huinv Reservoir in Quanzhou in 65,438+0965. In the more than 20 years of settlement, the village only gave birth to a baby girl, but not a baby boy. 1975, seven baby girls were born one after another, and the villagers were in distress. People nicknamed them "the seven fairies" and came to earth. Therefore, Gaoban Village has become a well-known "daughter village".

The villagers thought from the mystery of "geomantic omen" that the birth of children may be related to the water quality of three wells in the village. A villager eager to have a boy first moved his family to a stream and drank it instead. The next year, a boy was born. From 65438 to 0989, with the care and support of the government, the masses raised funds to install water pipes and introduced mountain springs to every household. From then on, "Feng Shui" began to turn, and three men and one woman were born in the village. Later, according to the appraisal of relevant departments, the original well water was polluted by cadmium, and the cadmium content in the water was particularly high.

Why do you only give birth to girls and not boys when the cadmium content in drinking water is particularly high? Scientists have confirmed through experiments that adding a certain amount of cadmium to the feed of pigs and mice will reduce the male birth rate of their offspring, while the female birth rate will increase significantly. It turns out that the increase of cadmium in human body will affect the maturation of male sperm and damage its vitality, which is the reason why "daughter village" only gives birth to girls but not boys.
