Recent publications from researchers at the University of New Mexico have identified microplastics—tiny plastic particles—in human testicular tissue. The analyzed samples from neutering operations and cadavers, showed these particles in humans and dogs.
The study examined 23 human testicles and 47 dog testicles, finding that human testicles contained nearly three times as many microplastics as those of dogs. Specifically, human testicles averaged 330 micrograms of microplastics per gram of tissue, while dog testicles contained 123 micrograms per gram.
They collected the testicles from autopsies of people ranging in age from 16 to 88 and from nearly 50 dogs after being neutered at local veterinary clinics.
Through animal studies, the most prevalent type of microplastic found was polyethylene. This finding, discovered in men, is thought to impact male fertility. Certain microplastics, such as PVC, can interfere with sperm production and disrupt hormones. A worry particularly alarming in light of the global decline in sperm counts, suggesting that microplastics might be a contributing factor.
While the full health effects of microplastics are still being investigated, evidence suggests they can elevate the risk of heart attacks, strokes, and tissue inflammation. These results stress the extensive reach of plastic pollution and its potential impacts on human health.
“Microplastics are everywhere,” says Dr. John Yu, a toxicologist in the College of Nursing at the University of New Mexico and lead author of the study. “The quantification of those microplastics in humans is the first step to understanding its potential adverse effects.”
Per Dr. Yu’s words, there’s a necessity to address plastic pollution. Microplastics can infiltrate even the most intimate areas of our bodies, potentially affecting reproductive health. As the use and disposal of plastics continues, understanding their effects on health is crucial.
Key Points to Understand:
What is Microplastics?
Microplastics are small plastic fragments less than five millimeters in size, originating from the breakdown of larger plastic items and products like cosmetics and synthetic clothing.
How Does Microplastics Enter the Body?
Microplastics can enter our bodies through ingestion, inhalation, and dermal absorption. They are present in everyday items such as bottled water, seafood, and even the air we breathe.
Health Risks of Microplastics
The health risks associated with microplastics are under study but are known to carry harmful chemicals that can cause inflammation and other health issues, including hormonal disruptions and organ damage.
Environmental Impact
Microplastics contaminate oceans, rivers, and soil; posing threats to wildlife and ecosystems. Marine animals often ingest microplastics, leading to health problems and mortality.
Reducing Plastic Pollution
Combating plastic pollution requires collective effort. This involves reducing plastic use, recycling properly, supporting policies that limit plastic production, and opting for products made from sustainable materials.
The presence of microplastics in human testicular tissue is a worrying discovery that reflects the broader issue of plastic pollution. By understanding and addressing this problem, we can work towards a healthier future for both people and the planet.
