ClearMicroplastics 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.

This systematic review examines how lifestyle factors, including microplastic exposure, affect male reproductive health. Research shows that microplastics, along with other environmental contaminants, may contribute to declining sperm quality and male infertility, which now affects up to 50% of infertility cases worldwide.
Microplastics Exposure Is Harmful to Male Reproductive Health
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.
Climate change, microplastics, and male infertility
This brief commentary discusses how climate change and exposure to environmental pollutants, including microplastics and endocrine-disrupting chemicals, may be contributing to the documented decline in male fertility over recent decades. While the exact causes remain unknown, the authors highlight the need for more research into how these environmental factors affect 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.
Adverse effects of microplastics and nanoplastics on the reproductive system: A comprehensive review of fertility and potential harmful interactions
This review summarizes how microplastics and nanoplastics can harm both male and female reproductive systems by disrupting hormone signaling, damaging sperm and egg cells, and causing inflammation in reproductive tissues. Smaller nanoplastics are especially concerning because they can cross biological barriers more easily and reach the testes and ovaries. With global infertility rates rising, the authors highlight environmental plastic exposure as a factor that deserves more research attention.
Reproductive toxicity of micro‐ and nanoplastics: Insights from experimental and human studies
This review examined 40 studies on how micro- and nanoplastics may affect human reproduction, finding that these particles have been detected in breast milk, placenta, ovaries, testes, and semen. Animal studies have linked plastic particle exposure to reduced sperm quality, disrupted egg development, smaller litter sizes, and possible effects passed to future generations. The evidence suggests that microplastic exposure may be a contributing factor worth investigating as global fertility rates continue to decline.
The Presence of Microplastics in Human Semen and Their Associations with Semen Quality
Researchers found microplastics in 75% of human semen samples tested, with an average of 17 particles per gram, including 15 different plastic types. Notably, higher levels of polystyrene microplastics were associated with lower sperm concentration and reduced sperm motility. This is one of the first studies to directly link microplastic presence in human semen to poorer sperm quality, adding to growing concerns about plastics and male fertility.
Effects of nano and microplastics on the reproduction system: In vitro and in vivo studies review
This review summarizes both lab and animal studies on how micro and nanoplastics affect the reproductive system in males and females. Evidence shows that microplastics can reduce sperm quality, damage ovaries, disrupt hormone levels, and even cross the placenta during pregnancy. The findings raise significant concerns about how widespread microplastic exposure might contribute to fertility problems and reproductive health issues in humans.
The Threat of Micro-/Nanoplastics to Male Fertility: A Review of the Data and the Importance of Future Research
This review synthesizes findings from 21 studies examining how micro- and nanoplastics and their associated endocrine-disrupting chemicals affect male reproductive health at the cellular level. Researchers found evidence of multiple toxicity mechanisms including damage to the blood-testis barrier, disruption of hormone signaling, oxidative stress, and structural damage to testicular tissues. The study notes that while these findings from cell and animal studies are concerning, translating the results to human health requires further research with realistic exposure conditions.
