Scientists have found that consuming an antioxidant supplement daily for three months does not help improve sperm quality in infertile men as previously thought and therefore can not be considered a therapy.
According to the authors, spermatogenesis – production or development The transport of mature spermatozoa lasts about 74 days, but reactive oxygen species have a greater negative effect during the transport phase of sperm than during spermatogenesis. Antioxidants are therefore beneficial even after a short interval.
"The results do not support the empirical use of antioxidant therapy for male infertility in couples who attempt to conceive naturally," said Anne Steiner, a professor at the University of Toronto. University of North Carolina at Chapel Hill, United States. , presented at the 34th annual meeting of ESHRE in Barcelona, the team conducted a clinical study of 174 couples where male partners daily took an antioxidant supplement in the form of tablets containing vitamins C, D3 and E, folic acid, zinc, selenium and L-carnitine, while the control group received placebo.
The results showed only a slight "overall" difference in sperm concentration between the two groups, and no significant difference in morphology – the shape and size of sperm – the ability of sperm to swim or swim in spermatozoa. move – or DNA fragmentation measures – damage in the sperm DNA.
In addition, the natural conception rate during the first three months was 10.5% in and just over nine percent in the placebo group, according to the researchers.
