Study Finds Cancer-Causing Microplastics in All 23 Human Testicles Tested

A new study published in Toxicological Sciences has found cancer-causing microplastics in 100% of the human testicles tested. The study examined 23 human testicles and 47 dog testicles, revealing that both contained microplastics. Human testicles had 330 micrograms of plastic per gram of tissue, nearly three times higher than the levels found in dogs. The most common types of microplastics identified were polyethylene and PVC. Researchers suggest that the presence of microplastics in testicles could be linked to the global decline in sperm counts observed over the past few decades. Additionally, crumbly polystyrene, a single-use plastic, has been highlighted as a significant contributor to this issue. This discovery raises concerns about male fertility, inflammation, and the pervasive nature of microplastics in the human body, which have also been associated with heart attacks and strokes.
