ClearConcerning 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.
Impact of nanoparticles and nanoplastics on female reproductive health
This review examines the evidence on how nanoparticles and nanoplastics may affect female reproductive health after entering the body through dermal, oral, and inhalation routes. Researchers note that these materials have been found in human ovarian tissue, raising concern about their potential effects on fertility and reproductive outcomes. The study highlights the need for more research into the reproductive health implications of nanoplastic 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.

Understanding the impact of nanoplastics on reproductive health: Exposure pathways, mechanisms, and implications
This review summarizes existing research on how nanoplastics (tiny plastic particles smaller than one micrometer) affect reproductive health in animals and potentially humans. Studies show that nanoplastics can accumulate in reproductive organs including the placenta, and evidence from animal studies links exposure to hormone disruption, reduced fertility, and developmental problems. The authors highlight a significant knowledge gap about nanoplastic effects on human reproduction, despite growing evidence that these particles reach our reproductive systems.
Impact of microplastics on female reproductive health: insights from animal and human experimental studies: a systematic review
This systematic review of 15 experimental studies found that microplastic exposure significantly impairs ovarian function, decreases fertility rates, and disrupts hormone levels in female subjects. Several studies also reported negative effects on embryo development and offspring health, though study quality varied and more rigorous research is needed to confirm mechanisms.
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.
Exposição De Microplásticos E Nanoplásticos Ao Tecido Ovariano: Uma Revisão Integrativa
This integrative review (in Portuguese) examines published evidence on the effects of micro- and nanoplastic exposure on female ovarian tissue morphology, finding disrupted folliculogenesis, oxidative stress, and hormonal interference reported across animal model studies.
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.
Plastic Particles and Female Fertility: Pathways, Toxicity, and Analytical Challenges
This review examines the pathways, toxicity mechanisms, and analytical challenges associated with microplastic and nanoplastic impacts on female fertility. Evidence from animal studies indicates that these particles can accumulate in ovaries and placental tissue, inducing oxidative stress, inflammation, and granulosa cell death that diminishes ovarian reserve. The study notes that microplastics have been confirmed in human placentas and umbilical cord blood, and may disrupt the hormonal axis governing reproduction.
Adverse health effects and mechanisms of microplastics on female reproductive system: a descriptive review
This review describes how microplastics, particularly polystyrene, can reach and accumulate in the female reproductive system through ingestion, inhalation, and skin contact. Animal studies suggest these particles may disrupt ovarian function, hormone balance, and fertility through oxidative stress and inflammation. While human evidence is still emerging, the research raises important questions about microplastic exposure and women's reproductive health.
The impact of microplastics on female reproduction and early life
This review examined the current evidence on how micro- and nanoplastics may affect female reproduction and early life development. Researchers found that studies in animals suggest microplastics can cross important biological barriers and may interfere with reproductive processes, though human data remains very limited. The study highlights the urgent need for standardized methods to measure human exposure and better understand potential reproductive health effects.
Reproductive toxicity and related mechanisms of micro(nano)plastics in terrestrial mammals: Review of current evidence.
This review of terrestrial mammal studies found that micro- and nanoplastics induce reproductive toxicity through oxidative stress, inflammation, endocrine disruption, and DNA damage, affecting both male and female fertility. In males, effects include blood-testis barrier disruption and impaired spermatogenesis, while females show compromised oocyte maturation, ovarian fibrosis, and diminished ovarian reserve, with particles also capable of crossing the maternal-fetal interface.
Exposure to micro- and nanoplastics and human reproductive outcomes: a systematic review

Effects of polystyrene nanoplastics on the female reproductive system in mice: Implications for ovarian function and follicular development
Researchers exposed female mice to polystyrene nanoplastics orally for 29 days and examined the effects on their reproductive systems. They found that nanoplastic exposure disrupted estrous cycles, impaired follicle development, and altered hormone levels in a dose-dependent manner. The study suggests that nanoplastics, due to their extremely small size, may cross biological barriers and accumulate in reproductive tissues, raising concerns about potential effects on fertility.
