OBJECTIVE To investigate the toxic mechanisms of Tripterygium wilfordii tablet(TWT) causing male mice reproductive damage and to identify detoxification targets. METHODS TWT was used to induce reproductive injury in mice. Metagenomic and metabolomics analysis were employed to perform differential analysis and functional analysis of gut microbiota and metabolites, aiming to identify the causative strains and metabolic pathways for reproductive injury, and to elucidate the mechanisms by which the microbiota and metabolites affect reproductive injury. RESULTS TWT significantly reduced the testicular index and sperm count in mice, leading to oxidative stress in testicular tissues. And TWT disrupted the gut microbiota and testicular metabolism. Supplementation with exogenous indole-3-lactic acid and Lactobacillus reuteri could regulate oxidative stress and improve testicular damage induced by TWT. CONCLUSION TWT cause reproductive damage by disrupting the gut microbiota and testicular metabolism. Lactobacillus reuteri and its metabolite, indole-3-lactic acid, improve male mice reproductive damage induced by TWHF tablets by regulating oxidative stress in testicular tissues.
