Summary:
- This study investigates the impact of microplastic exposure on the reproductive health and endocrine systems of zebrafish (*Danio rerio*), providing critical data on aquatic toxicology.
- The research highlights significant disruptions in gene expression related to the hypothalamic-pituitary-gonadal (HPG) axis, suggesting that microplastics act as endocrine-disrupting chemicals.
- The findings contribute to the broader scientific understanding of how environmental pollutants bioaccumulate and threaten biodiversity in freshwater ecosystems.
