Scientist are claiming that chemical phthalates, which is often used to make plastics more flexible is effecting fertility rates and leading to genital malformation.
Shanna Swan, Ph.D., professor of environmental medicine and public health at Icahn School of Medicine at Mount Sinai is claiming babies are being born with smaller penises.
This is based on her research which started with rats, finding that rat fetuses exposed to the chemical were more likely to be born with shrunken genitals. She later found that male human fetuses exposed to the chemical resulted in decreased anogenital distance.
Other findings she saw were more than a 50% decline in sperm levels among men in Western countries.
