Semen pathology induced by oxidative stress involves damage to cell membranes and DNA, leading to asthenozoospermia (reduced number of motile sperm in semen), necrosiscommia (lack of viability of spermatozoa in the ejaculate), and DNA fragmentation . Tremellen reports that 30% to 80% of cases of reduced male fertility result from the harmful effects of oxidative stress on sperm . The antioxidant system that protects sperm from free radicals, consists of both the enzyme complex, as well as non-enzymatic substances, which include vitamins C, A, E, B vitamins, coenzyme Qten, L-carnitine, glutathione and micronutrients such as zinc, selenium, and copper . The influence of lycopene and N-acetyl-cysteine on the quality of sperm is also of interest.
In a few education, the latest dating ranging from unmarried antioxidants and you will fertility rates was indeed analyzed, while has just the fresh new influence of numerous combos of several nourishment has actually even more started read

After 12 months of therapy, a significant improvement of mean sperm concentration (of 113.7%), sperm progressive motility (of 104.8%), and sperm with normal morphology (of 78.9%) was observed.
