The mean value of AOPP formation in 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 The variables with the different letters indicate significant differences between groups at p < 0.05. The variables with the same letter are not statistically significant. Data are mean values ± standard deviation (error bars).
