In Vitro Coexposure of Silymarin with Lithium Chloride Preserves Human Sperm Quality: A Useful Approach to Reduce Oxidative Damages

Table 3

Evaluation of catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) activity in human spermatozoa in the different groups.

Groups	CAT (U/sperm)	SOD (U/sperm)	GPx (U/sperm)
0 min	7.006 ± 0.01^a	4.331 ± 0.04^a	30.105 ± 1.01^a
Control	6.818 ± 0.02^a	4.145 ± 0.28^a	26.918 ± 0.89^a
Lithium chloride	5.241 ± 0.01^b	3.080 ± 0.01^b	7.715 ± 2.13^b
Silymarin + lithium chloride	6.560 ± 0.04^a	3.980 ± 0.04^a	22.771 ± 1.32^a
Silymarin	6.975 ± 0.03^a	4.135 ± 0.05^a	28.470 ± 0.58^a

Data are presented as means ± standard deviation. The means with the different letters are significantly different (one-way ANOVA, Tukey’s test, n = 6 for each group, ).
