Reproductive toxicity of micro- and nanoplastics
This review summarizes existing research on how micro- and nanoplastics harm reproduction across many species, from marine invertebrates to mammals. The particles can cause oxidative stress and hormone disruption, leading to reduced fertility, abnormal embryo development, and toxic effects that pass to offspring. The findings raise concerns that human reproductive health could be similarly affected given our increasing exposure to these particles.
The invisible Threat: Assessing the reproductive and transgenerational impacts of micro- and nanoplastics on fish
This review examines how micro- and nanoplastics can cross biological barriers in fish, accumulate in reproductive organs, and cause damage that passes down to offspring who were never directly exposed. The findings raise concerns about the long-term effects of plastic pollution on aquatic food chains, since fish that humans consume may have accumulated microplastics that affected their development and reproductive health.
Mechanistic insights into microplastic-induced reproductive toxicity in aquatic organisms: A comprehensive review
This review summarizes how microplastics cause reproductive harm in aquatic organisms by disrupting hormones, triggering oxidative stress, and interfering with cell death pathways. These effects lead to reduced fertility, abnormal egg and sperm development, and changes that can pass to future generations. Since microplastics accumulate through the food chain, these reproductive effects in aquatic life could have broader implications for ecosystem health and the seafood that humans consume.
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.

The Pressing Issue of Micro- and Nanoplastic Contamination: Profiling the Reproductive Alterations Mediated by Oxidative Stress
This review examined how micro- and nanoplastics affect reproductive health across aquatic and land-based organisms, focusing on oxidative stress as the primary damage mechanism. Researchers found that these plastic particles can reach the gonads through the bloodstream and even accumulate in human and mouse placenta, with harmful effects on sperm and egg development, embryo growth, and offspring survival. The severity of reproductive harm appears to increase with smaller particle sizes and longer exposure times.
Toxicity of microplastics and nanoplastics: invisible killers of female fertility and offspring health
This review summarizes research on how microplastics and nanoplastics affect female fertility across multiple species, from reproductive failure to developmental problems in offspring. The tiny particles can infiltrate the body through food, air, and skin, accumulating in reproductive tissues where they disrupt hormones and damage eggs. While animal studies cannot be directly applied to humans, the consistent findings across species raise serious concerns about the potential impact of microplastic exposure on women's reproductive health.
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.
