The plastic makes the female mouse

Most of these plastic products use bisphenol A. ( Photo: gallery )

When will female mice behave like male mice? When you give it a small amount of bisphenol A - the chemical is similar to estrogen. It is worth mentioning that this chemical is present in most types of cans, cans, bottles, food containers.

Ana Soto and colleagues at Tufts University in Boston experimented by continuously infusing bisphenol A into tissues of pregnant or lactating mice. As a result, female mice in the offspring have shown a masculine effect.

The amount of bisphenol A infused into their bodies is equivalent to the concentration found in human urine samples at the US Centers for Disease Control and Prevention.

According to the team, the offspring of the offspring were exposed to only half the amount of neurons in the area that controlled the reproductive cycle compared to normal, equivalent to the number of neurons in the male mice. They also exhibit more male-like behaviors during a standard behavioral test.

If this is true for people, then this is a potential disaster, because long ago bisphenol A has been warned to be a dangerous health hazard, but it is still widely used in children's toys. and plastic household items such as bowls, cups, briefcases, boxes, bottles, jars, beverage containers such as milk, beer, wine .

Meanwhile, Steven Hentges from the American Plastics Administration in Arlington, Virginia, pointed out that humans can metabolize bisphenol A, while mice are not because the chemical is injected directly into their tissues.
