Free radical processes (related to the formation of free radicals) play an important role in the development of infertility in men. Sperm cytoplasm contains small amounts of enzymes that capture free radicals, which is why they have quite a limited antioxidant protection. 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 . The influence of lycopene and N-acetyl-cysteine on the quality of sperm is also of interest.

In a few education, the new dating anywhere between unmarried antioxidants and virility pricing had been assessed, whereas has just new determine of several combos of a lot nutrients enjoys all the more started learnt

For the a beneficial meta-research had written in the 2014, it absolutely was reported that there can be little facts indicating one to antioxidant supplements in subfertile men may boost alive birth pricing to have couples attending fertility centers .

On number of subfertile boys whom acquired dos medications with zinc sulfate to have cuatro days (440 mg complete), the fresh new mean worth of semen volume, the fresh commission and you can overall regular sperm count and modern cum motility had been rather improved . It absolutely was in addition to discovered that zinc supplementation restored suitable diversity regarding clean air susceptibility and you will catalase interest throughout the semen of males which have asthenozoospermia . Ajina mais aussi al. noted that anti-oxidant medication predicated on within the vitro supplements out-of zinc, improved viewpoints of your own antioxidant standing index during the infertile males, however, they failed to prevent jizz lipid peroxidation . In one single study of 690 infertile guys that have idiopathic asthenoteratospermia, multiple supplements with selenium, at a serving out-of two hundred ?g on a daily basis and you will e vitamin at the a dosage regarding 400 IU each day, for around 100 months was utilized . Inside 52.6% away from players, an improve in the cum motility and you can/otherwise sperm morphology try observed. Likewise, as much as 10.8% away from couples ones boys became expecting.

In general, the human trials showed that an intake of 4–8 mg of lycopene supplements a day for 3–12 months, improve sperm parameters and is sufficient to treat male infertility . Devaraj et al. found that a daily dose of 30 mg of lycopene was required for a 9% age . 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 . N-acetyl-cysteine, administered orally in an amount of 600 mg/d for 3 months, had significant improving effects on the volume, motility, and viscosity of semen, and the serum total antioxidant capacity . 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 .
