In addition, they are sensitive to the detrimental effect of oxidative stress due to the high content of polyunsaturated fatty acids in the cell membrane. 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 .

In a study conducted by Safarinejad, 287 infertile men with idiopathic oligoasthenoteratozoospermia were treated with coenzyme Q10, with an oral dose of 300 mg twice a day . 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. The results of the meta-analysis, carried out by Lafuente et al., confirmed that coenzyme Q10 improves sperm parameters, however, there was no increase in live births or pregnancy rates .

All semen parameters significantly improved with N-acetyl-cysteine and selenium treatment. There was also a decrease in the concentration of follicle-stimulating hormone and an increase in serum concentration of testosterone .
