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

According to the Sydney Morning Herald, 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 the rates hypospadias – a congenital anomaly of the penis – have increased twice in Australia.

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 breeding problem for men ," said the researcher.

"When rates double, they can not be genetic defects: It takes years to spread through a population, so we know that must be of environmental origin ", 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 not yet any data at the population level to support this link.

The article points out that the country's government regulators reject this relationship between chemicals and human health, and other scientists are following that it is possible that it exists. 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 at the moment, it has not been shown to affect humans.
