What is it about?
zinc supplementation restores the oxido-sensitive index and catalase-like activity in spermatozoa and seminal plasma of asthenozoospermic subjects to normal ranges. Zinc supplementation enhances the quantitative and qualitative roperties of semen. Progressive motility correlates with the oxido-sensitive index level and catalase-like activity.

Why is it important?
Although several studies have considered the relationship between infertility and semen superoxide radical scavengers levels, no study on the effects of asthenospermia treatments such as oral zinc supplementation on superoxide radical scavenger activity, which are important in fertility of the individual, has been reported. The present study was conducted to examine the effect of zinc supplementation on the quantitative and qualitative characteristics of semen along with superoxide radical scavenging activity in the seminal plasma of asthenospermic patients.
Perspectives
superoxide dismutase activity may not be a useful indicator of the oxidative damage associated with physical characteristics of sperm, and a more appropriate marker of the levels of oxidative stress should be utilized to assess its relationship to sperm functions. The best proof is the oxido-sensitive index, because it indicates the exact value of balance between pro-oxidant and antioxidant enzymatic substances.
