Antioxidant Effect of the Castanea sativa Mill. Leaf Extract on Oxidative Stress Induced upon Human Spermatozoa

Figure 2

Differential pulse voltammogram (DPV) (a) and cyclic voltammogram (b) recorded for CEE 1 : 5 in water solution on a glassy carbon electrode. Scan rate: 20 mV/s. An anodic process (oxidation) at +0.55 V is recorded by differential pulse voltammetry and cyclic voltammetry methods. Other oxidation peaks were detected in DPV (asterisks).
