A new book finds the culprit behind shrinking penises and suicide sperm

We know environmental pollutants can lead to cancer, heart disease, and brain damage, but now a scientist links them to shrinking Penises.

Yes, you read that right. In her new book countdownReproductive epidemiologist Shanna Swan, Ph.D., argues that shrinking a particular male organ may be associated with everyday chemicals. If that’s not sobering enough for you, this is the book’s subtitle How our modern world is threatened Count sperm, Changing male and female reproductive development and endangering the future of mankind.

If Swan’s name sounds familiar, it may be because of 2017 study She helped with behaviors that were found to have seen men’s sperm counts drop by more than half in nearly 40 years in western countries.

What is to blame for shrinking penises?

When the penis gets smaller countdown blames a group of chemicals known as phthalates.

Phthalates are found in plastics, vinyl, floor and wall coverings, medical devices, and toys. They are also part of hairsprays, soaps and shampoos. You may have used a product with phthalates in the shower this morning.

Research has shown that maternal exposure to high levels of phthalate concentrates can alter male reproductive development in infants. Early data suggests that men whose mothers were exposed to high levels of phthalate have decreased testicular volume, which is linked to lower testicular function.

“It’s an unfortunate accumulation of effects from different perspectives,” writes Swan in the book.

In addition, young men with high levels of metabolized phthalates have poorer motility and sperm shape. You are also at risk for sperm apoptosis, which is a different way of saying sperm suicide.

Swan’s writing that “you can assume that no one wants to hear their sperm self-destruct,” could at least be one of the understatements of the decade.

Phthalates aren’t just bad for men, as high exposure is just as harmful for women. Premature ovarian failure, hormonal imbalances, and early menopause are just a few of the effects it has on women.

What happens next

Swan says she wrote the book to illustrate the harmful effects of chemical exposure. Currently, some companies have voluntarily stopped using phthalates, while the European Union plans to do so in the future. The US currently has no plans to regulate the chemicals.

While countdown came out recently, some are suggesting it might lead more people, especially men, to action. Link to an article about the book, climate activist Greta Thunberg tweeted “See you all on the next climate strike :)”
