The size of men’s genitals around the world is decreasing due to environmental pollution, which is expected to have a negative impact on childbirth. Over the past 40 years, the sperm count for men in the West has decreased by more than 50 percent on average.

According to a recent study, the size of men’s genitals is decreasing as global environmental pollution accelerates. According to Shana Swan, a professor of environmental medicine and public health at Mount Sinai Hospital in New York, boys born recently were more likely to have smaller genitals or deformities.

“Phthalates, a chemical used to manufacture plastics, adversely affect the endocrine system. It also affects childbirth, and if left unchecked, it could lead to a crisis of human extinction,” said Swan.

According to the research, environmental pollutants cause problems with the fetus’ hormones, resulting in a smaller male genital size. These environmental pollutants have already penetrated various areas of our lives, from toys to food.


As the size of men’s genitals around the world is decreasing due to environmental pollution, it is expected to have an adverse impact on childbirth.

It is not just the size of the male genitalia that gets smaller. The bigger problem is that the quality of sperm is also deteriorating. Also, exposure to environmental pollution decreased the amount of sperm. Swan feared that if environmental problems were not resolved dramatically by 2045, the quality of sperm emitted by men would gradually decrease and the birth rate would decrease.

According to a study published in 2017, 185 studies involving nearly 45,000 healthy men found that sperm counts in men in the West (US, European, and Australian) have decreased by more than 50% on average over the past 40 years.
