Summary

This narrative review summarizes the evidence that microplastics may harm male reproductive health through oxidative stress, hormone disruption, inflammation, and direct damage to reproductive cells. While animal studies show concerning effects on sperm quality, testicular function, and fertility, human studies are still lacking. The review calls for urgent research on microplastic impacts on human male fertility and for policies to reduce microplastic exposure.

Current evidence suggests that microplastics may impair male reproductive health through mechanisms like oxidative stress, hormonal disruption, inflammation, and cellular damage. However, the lack of human studies highlights the urgent need for robust research to clarify their impact on human male infertility. Furthermore, this review underscores the necessity for continued research to elucidate molecular mechanisms, inform preventative strategies, and guide regulatory policies addressing microplastic pollution and its health implications.
