ClearDisruptors on Male Reproduction – Emerging Risk Factors
This review of emerging risk factors for male infertility covers endocrine-disrupting chemicals, heavy metals, pesticides, radiation, and pharmaceuticals, including a section on microplastics and the plastic-associated chemicals that have been linked to hormonal disruption and reduced sperm quality. While microplastics are one of several disruptors discussed rather than the sole focus, the paper is relevant because it places microplastic exposure within the broader context of the global decline in sperm counts and male reproductive health over recent decades.
Environmental determinants of male infertility: emerging threats and technological interventions
This review examines how environmental contaminants, including microplastics, air pollution, heavy metals, and endocrine-disrupting chemicals, may contribute to declining male fertility.

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.
Impacto de los disruptores endocrinos derivados de plásticos en la regulación hormonal masculina: un análisis integral de la evidencia científica
This literature review compiled recent studies on how phthalates, bisphenol A, and microplastics from plastic products disrupt male hormonal regulation, finding evidence for reduced testosterone, impaired testicular synthesis, and alterations in the hypothalamic-pituitary-gonadal axis. The review calls for greater attention to plastic-derived endocrine disruptors in male reproductive health research.
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.
Environmental and microbiome determinants of sperm quality: a narrative review on male health
This narrative review examines how environmental factors, including microplastics and other emerging contaminants, affect male sperm quality and fertility. The study suggests that pollutants such as heavy metals, pesticides, phthalates, PFAS, air pollution, and microplastics can impair sperm parameters through various mechanisms, and highlights the role of the reproductive microbiome in mediating these environmental effects.
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.
Microplastics and Fertility
This paper reviews the growing body of evidence linking microplastic exposure to impaired human fertility, covering how microplastics and associated chemical additives can disrupt reproductive hormones and damage sperm and egg quality. It highlights the need for further research to establish dose-response relationships.
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.

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.
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.
Unraveling the threat: Microplastics and nano-plastics' impact on reproductive viability across ecosystems
This review summarizes research on how microplastics and nanoplastics affect reproduction across many species, from aquatic invertebrates to mammals including humans. In males, exposure leads to testicular damage, lower sperm quality, and hormone disruption; in females, it causes ovarian and uterine problems, inflammation, and reduced fertility. The evidence also shows these reproductive harms can be passed to offspring, raising serious concerns about long-term effects on human fertility.

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.
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.
