ClearMaternal exposure to polystyrene nanoplastics induces sex-specific cardiotoxicity in offspring mice
When pregnant mice were exposed to polystyrene nanoplastics, their offspring developed heart damage that differed between males and females. Female offspring lost more body and heart weight, while males showed signs of atherosclerosis and females showed viral heart inflammation markers. This study suggests that prenatal nanoplastic exposure could program sex-specific cardiovascular problems in children, raising concerns about plastic exposure during pregnancy.
Gender-specific effects of prenatal polystyrene nanoparticle exposure on offspring lung development
Researchers found that prenatal exposure to polystyrene nanoparticles impairs lung development in mouse offspring in sex-specific ways — females showed inflammation and disrupted surfactant proteins while males had impaired blood vessel growth — both increasing the risk of a serious lung condition called bronchopulmonary dysplasia.
Effects of polystyrene nanoplastic gestational exposure on mice
Researchers exposed pregnant mice to airborne polystyrene nanoplastics and studied the effects on both mothers and offspring. High-dose exposure caused fatty liver disease in the mothers and in adult female offspring, but not in male offspring, with each group showing different underlying molecular mechanisms. The study suggests that prenatal exposure to airborne nanoplastics may have sex-specific effects on metabolic health that persist into adulthood.
Sex differences in cardiac fibrosis induced by gestational exposure to polystyrene nanoplastics in mice offspring
Researchers exposed pregnant mice to polystyrene nanoplastics and examined the hearts of their adult offspring, finding dose-dependent cardiac fibrosis and cell death that differed between males and females. Male offspring showed greater changes in estrogen receptor gene expression compared to females, which may explain the observed sex differences in heart damage. The study suggests that prenatal nanoplastic exposure could have lasting effects on heart health, with males potentially more vulnerable.
Maternal exposure to polystyrene nanoplastics causes brain abnormalities in progeny
When pregnant mice were exposed to polystyrene nanoplastics, their offspring showed abnormal brain development including changes in neural stem cell function, altered brain structure, and cognitive problems. The effects were gender-specific, with some deficits appearing more strongly in one sex. This study raises concerns that nanoplastic exposure during pregnancy could increase the risk of neurodevelopmental problems in children.

This study examined the impact of polystyrene microplastic exposure on kidney and liver function in male and female albino rats, finding sex-dependent differences in organ pathology and biomarker responses after subchronic exposure.
Toxicological effects and mechanisms of renal injury induced by inhalation exposure to airborne nanoplastics
Researchers studied what happens to mouse kidneys after breathing in airborne polystyrene nanoplastics and found the particles accumulated in kidney tissue after entering through the lungs. The nanoplastics activated stress and inflammation pathways that led to kidney cell damage and death. Testing on lab-grown human kidney organoids showed they were even more sensitive to nanoplastic exposure than standard cell lines, suggesting developing kidneys in embryos could be particularly vulnerable.
Maternal exposure to polystyrene nanoplastics during gestation and lactation induces hepatic and testicular toxicity in male mouse offspring
Researchers exposed pregnant and nursing mice to polystyrene nanoplastics and studied the effects on their male offspring. The offspring showed reduced body weight, liver damage with inflammation and disrupted sugar metabolism, and testicular harm including decreased sperm counts. The findings suggest that nanoplastic exposure during pregnancy and breastfeeding can cause significant organ damage in the next generation.
Ferroptosis Is Involved in Sex-Specific Small Intestinal Toxicity in the Offspring of Adult Mice Exposed to Polystyrene Nanoplastics during Pregnancy
When pregnant mice were exposed to 80-nanometer polystyrene nanoplastics through inhalation, their offspring developed intestinal damage involving oxidative stress and a type of cell death called ferroptosis. Female offspring were more severely affected than males, showing sex-specific vulnerability to prenatal nanoplastic exposure. This study raises concerns that breathing in nanoplastics during pregnancy could harm the developing gut of unborn children, with potentially different effects on boys and girls.
Effects of nano- and microplastics on kidney: Physicochemical properties, bioaccumulation, oxidative stress and immunoreaction
Researchers exposed mice to polystyrene nano- and microplastics of varying sizes and tracked their accumulation and effects in the kidneys. They found that the particles changed their physical properties during digestion, accumulated in kidney tissue, and caused oxidative stress and immune responses. The study suggests that plastic particle size plays an important role in determining the extent of kidney-related harm.
Exposure to polystyrene nanoplastics impairs sperm metabolism and pre-implantation embryo development in mice
This study found that male mice given polystyrene nanoplastics by mouth showed significant harm to sperm function and early embryo development, with changes in gene expression that could affect offspring. The findings raise concerns that nanoplastic exposure could impair male fertility and potentially pass harmful effects to the next generation.
Comparing the effects of polystyrene microplastics exposure on reproduction and fertility in male and female mice
Researchers exposed both male and female mice to polystyrene microplastics for 30 to 44 days and found that the particles accumulated more in ovaries than testes, causing oxidative stress and reproductive damage in both sexes. Male mice had fewer viable sperm and more deformed sperm, while female mice had smaller ovaries with fewer eggs, and both sexes showed altered hormone levels and reduced fertility. This study suggests that microplastic exposure could contribute to declining fertility in both men and women.
Prenatal and postnatal exposure to polystyrene microplastics induces testis developmental disorder and affects male fertility in mice
Researchers exposed pregnant mice and their offspring to polystyrene microplastics from gestation through early life and found significant disruption to testicular development and male reproductive function. The exposed males showed reduced sperm quality, lower testosterone levels, and structural damage to testicular tissue. The study suggests that early-life microplastic exposure may have lasting effects on male fertility.
Polystyrene microplastics induced male reproductive toxicity in mice
Researchers exposed male mice to polystyrene microplastics of different sizes and found that the particles accumulated in testicular tissue and entered reproductive cells. After 28 days of exposure, sperm quality and testosterone levels declined, and tissue examination revealed disorganized sperm-producing cells and inflammation. The study suggests that microplastic exposure may pose risks to male reproductive health in mammals.
Maternal exposure to polystyrene nanoplastics impacts developmental milestones and brain structure in mouse offspring
Researchers exposed pregnant mice to polystyrene nanoplastics and studied the effects on their offspring's brain development. The study found that maternal nanoplastic exposure affected developmental milestones and brain structure in the young mice. The findings suggest that nanoplastic exposure during pregnancy may pose risks to fetal brain development, though more research is needed to understand the implications for humans.
Sex-specific gene expression alterations in response to ingested PVC microplastics in Wistar rats
Researchers examined sex-specific differences in gene expression changes in mice exposed to PVC microplastics via ingestion, finding that male and female animals responded differently at the molecular level. The sex-specific patterns suggest that biological sex may be an important variable in microplastic health risk assessments.
Maternal exposure to polystyrene nanoplastics leads to ovotoxicity in female mouse offspring
Researchers exposed pregnant mice to polystyrene nanoplastics throughout mating, pregnancy, and nursing, then examined the ovaries of their female offspring. They found that maternal nanoplastic exposure significantly reduced ovarian weight and follicle numbers in the offspring and lowered the expression of key antioxidant genes. The study suggests that nanoplastic exposure during pregnancy may pose risks to the reproductive development of female offspring.
Toxicity to the Male Reproductive System after Exposure to Polystyrene Nanoplastics: A Macrogenomic and Metabolomic Analysis
Researchers exposed male mice to polystyrene nanoplastics of different sizes through their drinking water for four months and found significant harm to reproductive function. The nanoplastics disrupted gene activity and metabolic pathways in the gut, which was linked to reduced sperm quality and testicular damage. The study suggests that long-term nanoplastic exposure through drinking water may pose risks to male reproductive health.
Comparative impact of polystyrene, rice bag-derived high-density polyethylene nanoparticles, and polystyrene–silver nanoparticle interactions in a 28-day in vivo study in male and female Wistar rats
Researchers gave rats daily doses of plastic nanoparticles for 28 days and found subtle signs of DNA damage, cholesterol changes, and liver stress — with females showing greater sensitivity in lipid metabolism and males experiencing reduced testicular weight from HDPE plastic nanoparticles. The study highlights that the health effects of nanoplastics differ by sex and can be worsened when multiple types of nanoparticles are mixed together.
Gestational exposure to micro and nanoplastics differentially impacts cardiac development and function in male and female rats throughout the lifespan
Researchers exposed pregnant rats to airborne micro- and nanoplastics and tracked heart development and function in their offspring from before birth through three months of age. They found that the exposure caused sex-specific cardiac changes, including altered heart wall thickness and chamber dimensions that persisted into adulthood. The study suggests that prenatal microplastic exposure may program lasting cardiovascular differences, with male and female offspring affected in distinct ways.
The emerging risk of exposure to nano(micro)plastics on endocrine disturbance and reproductive toxicity: From a hypothetical scenario to a global public health challenge
Researchers administered polystyrene nanoplastics orally to male rats for five weeks and found significant reductions in testosterone, LH, and FSH levels, sperm DNA damage, altered testicular gene expression, and dose-dependent histological lesions, indicating that nanoplastic exposure disrupts the hormonal axis governing male reproductive function.
The male reproductive toxicity after nanoplastics and microplastics exposure: Sperm quality and changes of different cells in testis
A mouse study compared the reproductive toxicity of nanoplastics versus microplastics and found that both damaged the testes after 12 weeks of exposure, but microplastics caused more severe harm in some measures. The plastics disrupted sperm production, caused inflammation and oxidative stress, and damaged the cells that support sperm development. These findings suggest that plastic particle exposure could contribute to male fertility problems, with different particle sizes affecting reproductive health through different biological pathways.
Adolescent exposure to polystyrene nanoplastics induces male reproductive damage via the microbiome-gut-testis axis
Researchers exposed adolescent rats to polystyrene nanoplastics for five weeks and observed dose-dependent damage to testicular tissue, disrupted spermatogenesis, and compromised blood-testis barrier integrity. The study revealed a novel microbiome-gut-testis axis mechanism, where nanoplastics altered gut bacteria composition, which in turn contributed to reproductive toxicity in developing males.
Polystyrene nanoplastics alter intestinal toxicity of 2,4-DTBP in a sex-dependent manner in zebrafish (Danio rerio)
Researchers exposed zebrafish to polystyrene nanoplastics combined with an industrial chemical called 2,4-DTBP and found that the toxic effects on the intestines differed between males and females. In males, the nanoplastics made the chemical's gut damage worse, while in females the combination actually reduced harm compared to the chemical alone. The study highlights that sex-specific biological differences can significantly change how organisms respond to combined plastic and chemical pollution.
