Description
Summary:Given the extensive use of plastic materials in modern society, there is an escalating concern about the potential risks associated with exposure to plastic products. This study investigated the impact of plastic leachates from boiled-water-treated cups, including polypropylene (PP), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polystyrene (PS), and polyethylene terephthalate (PET), on male reproductive health. Experimental mice were administered daily doses of the plastic leachates for 180 consecutive days. Histological analysis of the testes and epididymis was conducted, revealing vacuolization and absence of sperms in the seminiferous tubules of mice treated with PP, HDPE, LDPE, and PS, while PET exhibited lower reproductive toxicity. Furthermore, transcriptomic and metabolomic profiling were employed to identify key genes and metabolites related to plastic exposure. Transcriptome analysis showed significant changes in genes associated with spermatogenesis following exposure to leachates, while metabolome analysis indicated an impact on the lipid metabolism pathway. Overall, the study provides evidence that oral exposure to leachates from boiled-water-treated plastic cups could negatively affect spermatogenesis and lipid metabolism, thereby posing risks to male reproductive health. These findings offer crucial insights into the potential risks associated with plastic consumption and may advocate for the selection of relatively safe plastic cups for everyday use.
