Polystyrene microplastics impair sheep spermatogenesis by disrupting rumen microbiota-derived butyrate signaling

Microplastics are emerging environmental contaminants with male reproductive toxicity; however, their effects on ruminants and underlying mechanisms remain poorly understood. In this study, male Hu lambs were exposed to dietary polystyrene microplastics (PS-MPs) at 0, 75, and 150 mg/kg diet for 120 d, followed by a 180...
