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

Table 2

The levels of total antioxidant capacity as measured by FRAP (ferric reducing antioxidant power) and lipid peroxidation as measured by MDA (malondialdehyde) in human spermatozoa in the different groups.

Groups	FRAP (μmol/sperm)	MDA (nmol/sperm)
0 min	0.132 ± 0.001^a	0.905 ± 0.001^a
Control	0.126 ± 0.006^a	0.765 ± 0.011^a
Lithium chloride	0.012 ± 0.010^b	2.156 ± 0.021^b
Silymarin + lithium chloride	0.122 ± 0.002^a	0.515 ± 0.001^a
Silymarin	0.128 ± 0.006^a	0.733 ± 0.005^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, ).
