A groundbreaking study has revealed a concerning link between a father’s exposure to microplastics and an increased risk of metabolic diseases, such as diabetes, in his female offspring. Conducted by researchers at the University of California, Riverside (UC Riverside), the study emphasizes how environmental pollutants can affect future generations through paternal lineage.
Microplastics are tiny particles, measuring less than five millimeters, that originate from industrial waste and common consumer products. While these particles have previously been detected in human reproductive systems, this research—published in the Journal of the Endocrine Society—is the first to focus specifically on how a father’s exposure impacts the health of his children.
The research involved mice models where fathers were exposed to microplastics and fed a high-fat diet. The results showed that daughters were significantly more affected than sons. These daughters developed insulin resistance, a primary precursor to diabetes, and showed signs of liver inflammation. Interestingly, while the sons did not develop diabetes, they did experience a slight reduction in fat mass, highlighting a distinct gender-based reaction to the pollutants.
