It is obvious that pollution reduces the human penis

An environmental scientist has warned that human penises shrink and genitals generally become defective at birth due to pollution.

In his new book entitled Countdown, Dr. Shanna Swan, a professor of environmental medicine and public health at Icahn School of Medicine at Mount Sinai Hospital in New York City, warned that phthalates in the air cause people to suffer harmful consequences such as abnormal genital size, erectile dysfunction, lower sperm counts and dangerously low fertility rates.

A chemical used in the production of plastics, phthalates in the air affect the endocrine system which produces hormones designed to regulate almost all processes in the body. As a result, more babies are born with smaller penises, Swan wrote.


Her book examines how they affect sperm count as well as male and female reproductive organs in the modern era, and how pollution potentially “threatens the future of the human race”.

Pollution causes low shocks.

In her research, Swan studied phthalate syndrome, which caused rats to give birth to fetuses exposed to chemicals with smaller genitals.

In the case of men, she found that male babies exposed to chemicals in the womb had a shorter anogenital distance, meaning less penis volume.

The reason why this happens is that phthalates mimic the hormone estrogen, which is likely to disrupt the natural production of hormones in the human body and cause detrimental effects on the development of the sexual organs.

As for the way these phthalates reach the unborn baby, Swan thinks the chemical – used to make plastic products more flexible – is most likely transmitted through toys and food.

“Babies are now entering a world already contaminated with chemicals because of the substances they absorb in the womb,” she wrote in her book.

Swan’s findings are based on several expert reviews, one of which showed that sperm levels among men in Western countries have sunk by more than 50 percent in the past four decades.

Worryingly, she also predicted that with such a rapidly declining fertility rate by 2045, most men would become infertile.
