ClearToxic effects of microplastic and nanoplastic on the reproduction of teleost fish in aquatic environments
This review summarizes research on how microplastics and nanoplastics harm the reproductive systems of fish, covering effects on fertility, sperm quality, egg development, and offspring abnormalities. The tiny plastic particles enter fish through their digestive tract, gills, and skin, causing oxidative damage that disrupts reproduction at the molecular and cellular level. Since fish are a major protein source for humans, reproductive damage to fish populations could affect both food security and the transfer of microplastics through the food chain.
