Table 1.

Total thiol content in the human spermatozoal samples untreated/treated with FeAA, nicotine and FeAA + nicotine and/or unsupplemented/supplemented with Mn²⁺ (0.1 mM)

μ moles -SH/mg prot/min
Mn2+ (mM)	Untreated	Treated
		FeAA	Nicotine	FeAA + Nicotine
0	17.66 ± 1.57 (control)	18.56 ± 1.386	19.85 ± 1.047	21.518 ± 1.06*
0.1	19.78 ± 0.69	21.18 ± 1.27*	19.139 ± 0.59	24.66 ± 1.16*a

Each value represents the mean + SE of three independent observations;

^aP < 0.05 as compared with the Mn²⁺-supplemented samples treated similarly;

^*P < 0.05 as compared with the control samples
