Vitamin for sperm production1/12/2024 ![]() Male factor accounts for nearly half of cases of infertility presenting an abnormal semen analysis. Nevertheless, 10–15% of couples trying to achieve pregnancy remain childless. ![]() Study ID: ISRCTN48594239Īt the peak of reproductive capability, a healthy couple has an annual pregnancy probability rate of 80–85%. Retrospectively registered at ISRCTN (7th October 2016). ![]() There is need for more research in this matter that includes long term outcome data. Conclusionīoth analyzed groups displayed a positive short term effect on all sperm parameters however effect on density and motility was significantly better for the combined formulation. However, relative change (expressed as % increase of absolute values) for sperm density and overall progressive motility (including fast motility) was found to be higher for the combined micronutrient treatment group as compared to the mono-treatment using l-carnitine alone. Semen parameters (volume, density, overall progressive motility ) and percentage of sperm with normal morphology improved after 3 months in both groups as compared to baseline. Resultsīaseline characteristics were similar among studied groups (age and body mass indices). Sperm parameters were analyzed before and after treatment and groups comparisons performed. This was a prospective, open-labelled, nonrandomized study that included male subjects (20 to 60 years) with at least 1 year of subfertility and at least one pathological semen analysis who received 3 months treatment with a mono-substance (500 mg l-carnitine/twice a day, n = 156) or a combined compound (440 mg l-carnitine + 250 mg l-arginine + 40 mg zinc + 120 mg vitamin E + 80 mg glutathione + 60 μg selenium + 15 mg coenzyme Q10 + 800 μg folic acid/once a day, n = 143) for the same time period. a mono-substance (l-carnitine alone) on sperm parameters. This study was carried out to compare the short term effects of a combination of eight micronutrients including l-carnitine vs. However, comparative studies are still lacking. There are reports showing that l-carnitine alone or in combination with other micronutrients improve sperm parameters. Physcial activity and semenquality among men attending an infertility clinic.
