Effects of different doses of PS-MP and probiotics on malondialdehyde (MDA) levels of (A) sperm, (B) plasma and (C) testis in rats after 7 weeks. Sperms were adjusted to 106 cells/mL. Data are shown as the mean ± S.E.M. (n = 7 rats/group). Con: control; PS-MP1:1 mg/kg Polystyrene microplastic (PS-MP) per day; PS-MP5: 5 mg/kg PS-MP per day; PS-MP10:10 mg/kg PS-MP per day; PS-MP10 + Pro: 10 mg/kg PS-MP + 108 number of probiotics per day; Pro: 108 number of probiotics. The values with different letters (a–c) represent significantly different (p < 0.05) as analyzed by Duncan’s multiple range test. *P < 0.05 versus control group.
