Taking antioxidant supplements would have no beneficial effect on male fertility, according to a new study by researchers from the Eunice Kennedy Shiver National Institute of Child Health and Human Development.
They indeed tested the effects of vitamins C, E and D, selenium, 1-carnitine, zinc, folic acid, and lycopene on participants with fertility problems. Studies followed 171 couples in which the male partner had at least one sperm deficit, and the women had normal results. They were separated into two groups, one taking a placebo and the other taking an antixodyant supplement.
After three months, no significant difference was seen between those taking the placebo and those taking the antioxidant.
According to the authors, recruitment was stopped before they had the necessary number of participants, because no benefits had been perceived in the groups. The supplements in question are readily available to treat male infertility, and several studies have suggested their benefit.
