The mean value of the total antioxidant status on the rat sperm sample treated as follows: control, white NAE 0.22, 0.44, 0.88, 1.76 and 3.52 mg/mL, FeSO₄ and FeSO₄ following the white NAE 0.22, 0.44, 0.88, 1.76 and 3.52 mg/mL (NAE: N. nucifera petals aqueous extraction). ^a,b,c,d,e The variables with the different letters indicate significant differences between groups at p < 0.05. The variables with the same letters are not statistically significant. Data are mean values ± standard deviation (error bars).
