According to the Health Daily, cryptorchidism is a serious pediatric urinary system malformation.For children, testicles cannot be descended from the back of the lumbar peritoneal to the bottom of the scrotum according to the normal development process, and still stay in the abdomen.Recently, the research of Professor Wei Guanghui, a doctoral supervisor, gave an unexpected answer: plastic is the culprit that causes cryptor test.
The disaster caused by environmental estrogen
Studies have shown that androgen is a "power source" that promotes testicular decline.In the period of fetal development, if the level of estrogen in the mother is too high, therogen is "weak" in the growth and development of male reproductive organs such as testicles and lack of sufficient motivation for testicular declines, which will lead to cryptor testing.
What causes abnormal elevations of estrogen levels in the human body?
A number of studies at home and abroad suggest that a large amount of environmental estrogen produced by environmental pollution is difficult to remove.Environmental estrogen refers to a class of chemicals that exist in the environment. After entering the human body, this substance can cause endocrine, reproduction, development and behavior abnormalities.Most of the environmental estrogen is lipid -soluble. It is stable in the environment and is not easy to degrade. It can accumulate in the body and gradually achieve the pathogenesis of the pathogenic concentration.The residual pesticides on fruits and vegetables, plasticizers, detergents, and detergents in the environment can enter the children's body through placenta, milk, polluting water, food, or directly absorbing through the skin to produce adverse effects.Before the child was born, "if a large amount of environmental estrogen enters the mother and the estrogen level of the mother is too high, the fetus may appear." Wei Guanghui explained.
Plastic additives form a fatal pollution
"It is difficult for plastic products to be degraded naturally in the natural environment in the natural environment, causing fatal pollution & mdash; environment estrogen;" Wei Guanghui said that DEHP is a kind of plastic increase in the biological chain.During the manufacturing process of plastic products, only DEHP can be added to form plastic light and other qualities.However, even if this substance is deeply buried in the ground, it is difficult to degrade, and the environmental estrogen's effect can cause great pollution to the soil, and then pollute food and water.
