Histologic Assessment of Polyvinyl Chloride on the Uterus of Adult Wistar Rats
AI summary Read the abstract
Researchers administered polyvinyl chloride (PVC) microplastics orally to female Wistar rats at different doses for 21 days and examined uterine tissue. Histological examination revealed distorted uterine architecture across all PVC-treated groups, suggesting that microplastic exposure may have implications for reproductive health.
Backgrounds: Polyvinyl chloride (PVC), has emerged as a significant environmental concern with potential impacts on reproductive health. The uterus, a critical organ for female fertility and embryo development, may be vulnerable to microplastic exposure. This study investigated the histological effects of orally administered PVC microplastics on the uterus of adult Wistar rats. Methods: Fifteen adult female Wistar rats (150-200g) were randomly divided into five groups: A: control group, B: negative control group receiving cyclohexanone at 0.1 mg/kg, and C, D and E: Test groups receiving PVC at 0.1, 0.2, and 0.3 mg/kg. Animals were euthanized after 21 days of administration. Uterine tissues were harvested, fixed immediately in 10% formal saline and processed under a histological procedure. Results: Histological examination revealed distorted uterine architecture across all PVC-treated groups. Conclusion: Findings from the current study, showed that PVC-MPs impacted the histoarchitecture of the uterus and prolong and daily exposure can initiate fertility issue in the future, thereby preventing pregnancy in its totality.

Researchers administered polyvinyl chloride microplastics orally to adult female rats for 21 days and examined the effects on uterine tissue. Histological examination revealed distorted uterine architecture across all PVC-treated groups compared to controls. The findings suggest that PVC microplastic exposure may negatively impact reproductive organ structure, raising concerns about potential fertility implications from prolonged exposure.
Chronic Exposure to Polystyrene Microplastics and Its Expected Effects on Tissue Remodeling and Follicular Function in Female Rats: a Proposed Histopathological Study
AI summary Read the abstract
Scientists are planning a study to see how tiny plastic particles, called microplastics, might harm the uterus and ovaries in female rats over time. Since microplastics are known to travel through the body and cause cell damage elsewhere, this research could reveal whether long-term exposure affects reproductive health and fertility, an important question given how common these particles are in our food, water, and air.
The risk of short-term microplastic exposure on female reproductive function: A rat model study
AI summary Read the abstract
Researchers investigated the effects of short-term microplastic exposure on female reproductive function in rats and found that even brief exposure disrupted hormone levels and altered ovarian and uterine tissue. Higher concentrations of microplastics led to thinning of the uterine lining and changes in steroid hormone receptor expression. The study suggests that even intermittent microplastic exposure may pose risks to reproductive health.
The Histopathological and Genetic Effects of Long-Term Treatment with High-Molecular-Weight Polyvinyl Chloride on Various Organs of Young Wistar Rats
AI summary Read the abstract
Researchers fed young Wistar rats food containing 1% or 2% polyvinyl chloride for eight weeks, finding histopathological damage to the intestines, liver, kidney, and spleen, along with genetic effects including DNA fragmentation, demonstrating organ-level toxicity of chronic PVC microplastic ingestion.
