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 brand new matchmaking anywhere between single antioxidants and you can fertility prices have been analyzed, while recently the influence of various combos of several nutrition have increasingly started analyzed
Into the an effective meta-studies had written into the 2014, it had been reported that you will find nothing proof indicating you to anti-oxidant supplementation inside the subfertile people may raise real time beginning rates to own partners planning fertility centers .

About group of subfertile men just who received 2 tablets having zinc sulfate having 4 weeks (440 milligrams total), the brand new imply value of sperm frequency, the fresh new percentage and you will total typical sperm fertility and you may progressive spunk motility was in fact significantly enhanced . It had been together with learned that zinc supplements restored ideal variety out-of clean air sensitiveness and you may catalase hobby from the semen of men which have asthenozoospermia . Ajina mais aussi al. listed you to anti-oxidant treatment according to when you look at the vitro supplements off zinc, escort reviews Edinburg TX enhanced values of the anti-oxidant condition index for the infertile boys, not, it don’t prevent cum lipid peroxidation . In one study of 690 infertile people which have idiopathic asthenoteratospermia, simultaneous supplementation that have selenium, from the an amount regarding 200 ?g daily and e vitamin at a dose off eight hundred IU on a daily basis, for around one hundred days was utilized . When you look at the 52.6% out of participants, an improvement in the cum motility and you will/otherwise cum morphology is actually noticed. On the other hand, as many as ten.8% regarding couples of those guys 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 .
