Environmental scientist Dr. Shanna Swan warned in her new book titled Countdown that human penises shrink and deform due to pollution.

The cause of the shrinkage, which Swan says is an existential crisis facing humanity due to declining fertility rates, is due to the presence of phthalates commonly found in manufactured plastics.

Phthalate esters impact the human genitals by altering the hormone-producing endocrine system and, as a result, have led to the birth of more baby boys with small penises.

Swan based his research on the study of phthalate syndrome in rats, in which exposure of fetuses to the chemical increased the likelihood of the rat being born with shrunken genitals.

In humans, Swan found that male babies exposed to the chemical in the womb were more likely to have a shorter anogenital distance, which correlated with expected penile size.
The chemical’s origins come from toys and baby food and work by mimicking the hormone estrogen and disrupting the natural production of hormones in humans, later affecting sexual development in children as well as behavior in humans. the adults.

In a previous academic study published by Swan in 2017, it was found that sperm levels have dropped by more than half over the past 40 years, based on a review of 185 studies.

Swan believes most men will be unable to produce viable sperm by 2045.
