ClearNano and microplastics: unveiling their profound impact on endocrine health
This review summarizes existing research showing that micro- and nanoplastics can disrupt the endocrine (hormone) system, altering reproductive hormones, thyroid function, and gene expression in lab and animal studies. Exposure to these particles triggered inflammation markers and oxidative stress in hormone-producing organs, suggesting that widespread plastic pollution may be contributing to rising rates of hormonal and reproductive health problems.
A review of the endocrine disrupting effects of micro and nano plastic and their associated chemicals in mammals
This review summarizes how micro- and nanoplastics carry hormone-disrupting chemicals that can interfere with the thyroid, reproductive organs, and other parts of the endocrine system in mammals. Because these chemicals are not tightly bound to the plastic, they can leach into milk, water, and food, potentially disrupting hormone function in humans who consume them.
The endocrine disrupting effects of nanoplastic exposure: A systematic review
This systematic review summarizes research on how nanoplastics, the smallest plastic particles, can disrupt the hormonal system. The evidence from lab studies suggests nanoplastics may interfere with thyroid function, reproductive hormones, and stress responses. These findings raise concerns because endocrine disruption can lead to fertility problems, metabolic issues, and developmental effects in humans.
Human exposure to micro- and nanoplastics: a mechanistic perspective of health risks associated with metabolic and reproductive functions
This review examines how micro- and nanoplastics enter the human body through food, air, and skin contact, and the mechanisms by which they may disrupt metabolic and reproductive health. Researchers describe how these particles are absorbed through the gut, enter the bloodstream, and accumulate in organs where they can trigger inflammation, oxidative stress, and hormonal disruption. The evidence indicates that micro- and nanoplastics, particularly those carrying endocrine-disrupting chemicals, may pose significant risks to fertility and metabolic function.
Implications of plastic-derived endocrine disruptors on human health
This review summarizes how chemicals released from plastics, known as endocrine disruptors, can interfere with the body's hormone systems. Common substances like BPA and phthalates mimic or block hormones, contributing to obesity, diabetes, reproductive problems, and developmental issues in children. Micro- and nanoplastics make the problem worse because they can release these hormone-disrupting chemicals inside the body after being ingested or inhaled.
Microplastics, Endocrine Disruptors, and Oxidative Stress: Mechanisms and Health Implications
This review examines how microplastics and nanoplastics trigger oxidative stress as a central mechanism of toxicity across multiple organ systems, including reproductive, cardiovascular, hepatic, and neurological tissues. The study highlights that these particles often carry endocrine-disrupting chemicals like bisphenol A and phthalates, which together generate reactive oxygen species, impair mitochondrial function, and compromise antioxidant defenses.
"Unseen Dangers: The Effects of Micro- and Nanoplastics on Human Reproductive Health - A Narrative Review"
This review examines the effects of micro- and nanoplastics on human reproductive health, covering evidence from in vitro, animal, and epidemiological studies showing that plastic particles can disrupt hormone signaling, sperm function, ovarian development, and placental integrity.
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.
Threats of nano/microplastics to reproduction and offspring: Potential mechanisms and perspectives
This review summarized the evidence on how nano- and microplastics threaten reproduction and offspring health across multiple species, including fish, invertebrates, and mammals. The authors outlined potential mechanisms by which these plastic particles disrupt endocrine function, gonadal development, and embryonic development.
Effects of micro(nano)plastics on the reproductive system: A review
This review summarizes research on how micro and nanoplastics affect the reproductive system in both animal studies and cell experiments. Evidence indicates these particles can cross biological barriers, accumulate in reproductive organs, and disrupt hormones, egg development, and sperm quality. While human studies are still limited, the animal data suggests microplastic exposure may be a meaningful concern for reproductive health.
Endocrine Toxicity of Micro- and Nanoplastics, and Advances in Detection Techniques for Human Tissues: A Comprehensive Review
This review summarizes growing evidence that micro- and nanoplastics contain or carry endocrine-disrupting chemicals that interfere with hormones throughout the body, triggering oxidative stress, inflammation, and cell death in hormone-producing tissues. The paper also reviews new detection methods that can identify and measure these tiny plastic particles in human blood, tissue, and other biological samples, which is essential for understanding real-world health impacts.
PLASTAMINATION: Outcomes on the Central Nervous System and Reproduction.
This review assessed evidence for neurotoxic and reproductive effects of both biodegradable and conventional micro- and nanoplastics, finding that plastic particles and their chemical additives can cross the blood-brain barrier and disrupt hormone systems, with concerning implications for nervous system and reproductive health.
Concerning influences of micro/nano plastics on female reproductive health: focusing on cellular and molecular pathways from animal models to human studies
This review summarizes research showing that micro- and nanoplastics can harm the female reproductive system in multiple ways, from reducing ovarian reserves and disrupting hormone balance to accumulating in the placenta and breast milk. Animal studies show these particles trigger oxidative stress and inflammation in reproductive tissues, and human studies have confirmed their presence in placental tissue and infant feces, raising concerns about effects on fertility and fetal development.
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.
Microplastics as Emerging Contaminants: Investigating their Potential to Alter Human Metabolic and Endocrine Systems
This review investigated the potential of microplastics to alter human hormone signaling, synthesizing evidence that plastic particles and their chemical additives can act as endocrine disruptors at environmentally relevant concentrations.
