Probiotics improve polystyrene microplastics-induced male reproductive toxicity in mice by alleviating inflammatory response
Researchers found that giving mice probiotics (beneficial bacteria including Lactobacillus and Bifidobacterium) helped protect against reproductive damage caused by polystyrene microplastics. The microplastics disrupted gut bacteria and triggered inflammation that traveled to the testes via the gut-testis connection, reducing sperm quality and testosterone levels. Probiotic treatment restored healthy gut bacteria and reduced the inflammatory response, suggesting that maintaining gut health could help counteract some reproductive harm from microplastic exposure.
Novel probiotics adsorbing and excreting microplastics in vivo show potential gut health benefits
Researchers screened 784 bacterial strains and identified two probiotic strains that can stick to microplastic particles in the gut and help remove them from the body. In mice, these probiotics increased microplastic excretion by 34% and reduced the amount of plastic remaining in the intestine by 67%. This is the first study to show that specific probiotics could help the body get rid of ingested microplastics and reduce gut inflammation caused by them.
