Two Australian researchers from the University of Melbourne, Andrew Pask and Mark Green, claim that some chemicals found in plastics are responsible for the size of the male genitalia is reduced and that more and more males are born with defects in this organ
The researchers based their findings on the study of animals exposed to these chemicals, as well as on the analysis of human data showing that hypospadias rates – a congenital penis abnormality – increased twice in Australia. 19659002] According to Pask, the chemicals that can affect humans are BPA, phthalates (both used in plastics), parabens (in toothpastes and cosmetics) and atrazine (a herbicide) . "Exposure to these chemicals is the number one reproductive problem in men," says the researcher.
"When rates double, they can not be genetic defects: they take years to spread in a population, and then we know that it must be of environmental origin," he said. Pask.
In addition, the scientist points out studies that show that exposure to chemicals known as endocrine disruptors can reduce the size of the penis, although there is no data available .
The article highlights that the country's government regulators reject this relationship between chemicals and human health, while other scientists say that it may exist. Some plastics, according to the note, may release chemicals that look like human sex hormones. In animal studies, exposure to these products can cause reproductive problems, while for now, it has not been shown that they affect humans.
