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.

Toxicological effects of micro/nano-plastics on human reproductive health: A review

This review summarizes research on how micro- and nanoplastics affect human reproductive health in both men and women. Evidence from animal and lab studies shows that these particles can accumulate in reproductive organs, disrupt hormones, damage eggs and sperm, and cause inflammation and oxidative stress. While human studies are still limited, the growing body of evidence suggests that microplastic exposure is a potential threat to fertility that warrants further investigation.

Microplastics and male reproductive system: A comprehensive review based on cellular and molecular effects

This comprehensive review examines how microplastics affect the male reproductive system at cellular and molecular levels, drawing on studies from multiple scientific databases. Researchers found that microplastics can damage testicular structure and function, impair spermatogenesis, and disrupt sperm parameters through mechanisms including oxidative stress, inflammation, and activation of cell death pathways. The review highlights that microplastics reduce ATP production and trigger signaling cascades that may contribute to male fertility problems.
