What happens when microplastics reach the testes? Study shows autophagy and cell loss

Researchers found that microplastics from everyday plastic tableware accumulate in human semen and, although not linked to semen quality in the full cohort, were associated with altered sperm parameters in specific subgroups. Experimental models confirmed that 50 nm polystyrene particles trigger autophagy and apoptosis via the FOXA1/MAP3K1/p38 pathway, impairing sperm structure and function.
