Overview

A recent small study found that human testicles contain higher levels of microplastics and nanoplastics compared to animal testes and human placentas. The study, coauthored by toxicologist Matthew Campen and published in the journal Toxicological Sciences on May 15, revealed that these tiny plastic particles, often nano-scale and resembling small broken bits from old plastics, can invade cells and tissues in major organs. Experts warn that they may carry endocrine-disrupting chemicals, potentially affecting the reproductive system.

The study tested 23 preserved human testes and compared them with 47 dog testes. It found that the levels of microplastics in human testes were three times higher than those found in dogs, highlighting the extent of plastic ingestion in human bodies. The predominant types of plastics found in both species were polyethylene and PVC, which can contain chemical additives and heavy metals.

According to Campen, this discovery calls for urgent research to understand the possible role of microplastics in reproductive issues and certain cancers. The study’s findings emphasize the need for action to address the presence of microplastics in the human body.
