Microplastics Exposure Is Harmful to Male Reproductive Health
Summary
This chapter reviewed evidence on how microplastic exposure may harm male reproductive health through multiple pathways including ingestion and inhalation. The study examined mechanisms by which microplastics may disrupt reproductive function, including hormonal interference, oxidative stress, and inflammation in reproductive tissues, suggesting that widespread environmental microplastic contamination warrants attention as a potential factor in male fertility concerns.
This chapter will delve into the burgeoning concern surrounding microplastics (MPs) exposure and its insidious impact on male reproductive health. MPs, ubiquitous environmental pollutants stemming from the degradation of plastic products, have permeated various ecosystems and consequently found their way into the human body through multiple exposure routes, such as ingestion via food and water, and inhalation of airborne MP particles. The scope of this chapter encompasses an in-depth exploration of the mechanisms through which MPs exert their deleterious effects. It will examine the potential for MPs to induce oxidative stress in male reproductive tissues, leading to damage of sperm cells and disruption of the blood-testis barrier. Furthermore, the endocrine-disrupting properties of MPs will be scrutinized, as these pollutants can interfere with the normal hormonal regulation of the male reproductive system, affecting testosterone production and spermatogenesis. In addition, the chapter will present epidemiological evidence linking MPs exposure to adverse reproductive outcomes in men, such as reduced sperm quality, including decreased sperm count, motility, and morphology, as well as an increased risk of male infertility. Animal studies that have provided crucial insights into the dose-response relationships and the potential for transgenerational effects of MPs on male reproductive health will also be discussed. By synthesizing the existing body of knowledge, this chapter aims to highlight the urgent need for further research and public health interventions to mitigate the potential harm of MPs to male reproductive health.

Microplastics and impaired male reproductive health—exploring biological pathways of harm: a narrative review
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.
Microplastics: A Threat for Male Fertility
This review examines the growing evidence that microplastics may pose a threat to male fertility in mammals. Researchers found that these tiny plastic particles can enter the body through food and water, accumulate in tissues, and carry environmental pollutants that may act as hormone disruptors. Recent studies suggest that microplastic exposure is associated with changes in sperm quality, making them a potential concern for reproductive health.
Microplastics May Be a Significant Cause of Male Infertility
This review examines the potential link between microplastic exposure and the decline in male fertility observed over recent decades. Researchers reviewed evidence showing that microplastics can accumulate in reproductive tissues and may damage sperm quality through oxidative stress, hormonal disruption, and inflammatory responses. The study suggests that microplastics deserve serious attention as a possible contributing factor to rising male infertility rates.
Research Progress in Reproductive Toxicity of Micro- and Nanoplastics on Males and Its Mechanisms
This review summarized research on the reproductive toxicity of micro- and nanoplastics (MNPs) in males, finding that MNPs accumulate in reproductive organs and cause toxicity through oxidative stress, hormonal disruption, and DNA damage, with implications for both animal and human reproductive health.
The Microplastics and Human Health: Focus on the Reproductive System
This review examined evidence that microplastics accumulate in human reproductive tissues and evaluated their potential effects on fertility and reproductive health.
