Microplastics and nanoplastics found in human and dog testicles, which cause fertility problems

In a surprising revelation, researchers from the University of New Mexico have discovered the presence of microplastics and nanoplastics in the testicles of all human subjects and dogs involved in a study of 70 participants. This finding underscores the widespread infiltration of microscopic plastic particles into the human body, likely through contaminated food, water and air.

The study's lead author, John Yu, expressed his surprise at the prevalence of plastics in the male reproductive system. He suggested that this could be related to the overall decline in male fertility, particularly sperm count. Tracey Woodruff, director of the Center for Environmental Research and Translation for Health, called the research “a wake-up call for policymakers.”

The first recorded study of plastic debris in the ocean dates back to 1972, when scientists discovered tiny particles of plastic in the mid-Atlantic. The study of plastic debris gained momentum after the discovery of the “Great Pacific Garbage Patch,” the largest accumulation of plastic in the open ocean, in 1996. Over the past two decades, the increase of discoveries and public awareness campaigns have brought the problem of the ocean. pollution at the top.

In 2012, researchers discovered that the majority of plastic pollution consisted of tiny, often invisible pieces of microplastics. Since then, scientists have been investigating the origins of microplastics, their travel patterns, their infiltration into living organisms and their impact on ecosystems.

Richard Thompson, Professor of Marine Biology and Director of the University's Marine Institute, said microplastics have been found in all beach sand samples, whether in Australia, Asia, Europe, North or South America . Microplastic pollution has been detected in the deep sea, in the Arctic ice and in the intestines of hundreds of fish in the English Channel.

According to the United Nations, 400 million tons of plastic waste are produced every year. A 2020 study reported that more than half of the world's single-use plastic waste comes from 20 petrochemical companies, with ExxonMobil identified as the biggest offender. It is estimated that 90% of single-use plastic is produced by just 100 companies.
