Protection of Exogenous Antioxidant of Cinnamomum burmanii as a Hepatoprotective on the Toxicological Responses of Nanoplastics in Rats (Rattus norvegicus L.)

Researchers tested whether Cinnamomum burmanni leaf extract (CLE) protects rat liver function from polystyrene nanoplastic toxicity, administering NPs orally for 14 days with or without 100–400 mg/kg CLE for 28 days. NPs caused oxidative stress and liver damage, while CLE at 200–400 mg/kg significantly reduced hepatotoxicity markers and restored antioxidant enzyme activity, suggesting hepatoprotective potential against nanoplastic-induced toxicity.

Pharmacotherapeutic potential of ginkgetin against polystyrene microplastics–instigated testicular toxicity in rats: A biochemical, spermatological, and histopathological assessment

In a rat study, polystyrene microplastics caused significant damage to the testes, including reduced sperm quality, oxidative stress, and tissue inflammation, but the natural plant compound ginkgetin was able to partially reverse this damage. Ginkgetin worked by boosting antioxidant defenses and reducing the inflammatory response triggered by the microplastics. This suggests that natural antioxidant compounds might help protect male reproductive health from the harmful effects of microplastic exposure.

Attenuative effect of astilbin on polystyrene microplastics induced testicular damage: Biochemical, spermatological and histopathological-based evidences

Researchers found that astilbin, a natural plant compound, significantly reduced testicular damage caused by polystyrene microplastic exposure in rats. The microplastics disrupted hormone levels, sperm quality, and testicular tissue structure, but astilbin treatment counteracted these effects by boosting antioxidant defenses and reducing inflammation.

The presence of microplastics in human semen and the protective role of nicotinamide mononucleotide against polystyrene nanoplastics-induced reproductive and early embryonic toxicity

Researchers detected microplastics, including polystyrene, in human semen samples using laser direct infrared spectroscopy, confirming that these particles reach the male reproductive tract. In laboratory and mouse experiments, polystyrene nanoplastics impaired sperm motility, increased oxidative stress, and disrupted early embryonic development in a dose-dependent manner. The study found that nicotinamide mononucleotide (NMN) effectively reversed many of these harmful effects by restoring antioxidant capacity, suggesting a potential protective intervention.

Toxic Effects of Immunofluorescent Polystyrene Nanoplastics on Rat Testicular Tissue

Researchers exposed rat testicular tissue to fluorescent polystyrene nanoplastics at two different doses for one month and found that the particles accumulated in the reproductive organs. Higher doses led to increased oxidative stress, tissue damage, and changes in biochemical markers associated with reproductive function. The study suggests that nanoplastic exposure may pose risks to male reproductive health, though more research is needed to understand the implications for humans.

Impact of polystyrene microplastic exposure at low doses on male fertility: an experimental study in rats

Researchers exposed adult male rats to varying doses of polystyrene microplastics and found dose-dependent declines in semen quality along with disrupted reproductive hormone levels. Higher doses caused increased oxidative stress, mitochondrial damage, and inflammatory responses in testicular tissue. The study suggests that even relatively low doses of microplastic exposure may have adverse effects on male reproductive health in animal models.

Lycopene supplement mitigates polystyrene microplastics (PS-MPs)-induced reproductive alteration in rats via modulation of steroidogenic enzymes, inhibition of apoptosis and oxido-inflammatory reaction

Researchers found that lycopene, a natural antioxidant found in tomatoes, helped protect male rats from reproductive damage caused by polystyrene microplastic exposure. The microplastics disrupted hormone levels and sperm quality, but lycopene supplementation reduced oxidative stress and inflammation in reproductive tissues. The study suggests that dietary antioxidants may help counteract some of the harmful reproductive effects associated with microplastic exposure.

Astragalus Polysaccharides Ameliorate the Toxic Effects of Polystyrene Nanoplastics on Boar Sperm

Scientists found that tiny plastic particles called nanoplastics can damage sperm cells by causing harmful chemical reactions, but a natural compound from the Astragalus plant can help protect against this damage. This study used pig sperm in lab dishes, so we don't know yet if the same protection would work in humans. The findings matter because microplastics are everywhere in our environment and food, and this research suggests natural antioxidants might help reduce their potential harm to reproductive health.

Oral exposure to polystyrene nanoplastics altered the hypothalamic–pituitary–testicular axis role in hormonal regulation, inducing reproductive toxicity in albino rats

This study found that oral exposure to polystyrene nanoplastics disrupted the hormone signaling pathway between the brain and testes in male rats, leading to reproductive damage. The nanoplastics interfered with the hormones that regulate sperm production and testicular function. These findings add to growing evidence that nanoplastic exposure through food and water could be a contributing factor to declining male fertility.
