From: Chronic exposure to polystyrene microplastics induced male reproductive toxicity and decreased testosterone levels via the LH-mediated LHR/cAMP/PKA/StAR pathway

PS-MPs exposure induced reproductive toxicity in male mice. Mice were given drinking water containing different sizes of PS-MPs at 100 μg/L and 1000 μg/L for 180 continuous days. A The paired testis/body weight index was assessed (n = 15). B The paired epididymis/body weight index was analyzed (n = 15). C The viability of sperm was detected (n = 15). D The rate of sperm abnormality was calculated (n = 15). E The impact of PS-MPs on testis structures was examined by H&E staining. Arrows: abnormal structure. Data represent means ± SD. *P < 0.05, **P < 0.01, ***P < 0.001 vs. control. #P < 0.05, ##P < 0.01 vs. 100 μg/L group
