It's not just about climate, food choices, and how active we are - pollution can also affect our fertility, libido and even the size of the male penis.

According to the Environmental and Reproductive Health Epidemiologist Dr. According to Dr. Shanna H. Swan, the modern world today threatens sperm counts by altering the reproductive development of men and women and damaging the future of the human race. This woman studies the correlation between smaller penises, lower sperm counts, and the use of industrial chemicals in everyday products.

"Chemicals in our environment and unhealthy lifestyles upset our hormonal balance"

The author of the study has previously participated in a similar study on the decrease of sperm count between 1973 and 2011. The new Dr. Swan's study reveals how industrial pollution and chemicals cause low sperm counts, affect fertility rates - a modern man, she writes, not only has half the amount of sperm that his grandfather had, but the penis itself is smaller.

"Chemicals in our environment and an unhealthy lifestyle upset our hormonal balance, causing varying degrees of reproductive problems," she says. "In some parts of the world, an average twenty-year-old woman is less fertile today than her grandmother at the age of 35."

According to Dr. According to Swan, this "global existential crisis" reduces the number of sperm and leads directly to a decrease in penis size and testicular size. "The current state of reproductive problems cannot continue for much longer without endangering human survival," writes Dr. Svona. 'Of the five possible criteria which endanger a species, only one must be met; the current human situation corresponds to at least three. "

Dr. Swan also explores how contaminants can affect our libido, explaining that “We found a link between female phthalate levels and their sexual satisfaction” researchers in China found that workers with higher levels of bisphenol A in the blood, commonly known as BPA, were more likely to experience sexual problems, including reduced libido. "

So are we destined to experience that future generations will have fewer and fewer penises, or can we do something about it?

According to Swan, buying organic products and using plastic as little as possible in everyday life will help prevent the effects of chemicals on the individual. She even recommends eating home-cooked meals instead of eating out, as food packs and gloves used by restaurant staff transfer phthalates to food, which then enters the body.

If not for the sake of the environment, then it is time to fight pollution to protect our penises and civilization. As Swan writes, "We must do everything we can to protect our fertility, the destiny of humanity and the planet."
