Researchers studied 80 healthy men, aged 22 to 80, and found the older men who had the highest levels of vitamin C, E, zinc and folate, had 20% less sperm DNA damage compared to older men who consumed the least amount of vitamins.
"This means that men who are at increased risk of sperm DNA damage because of advancing age can do something about it," said co-author Andy Wyrobek, of Berkeley Lab's life sciences division in California, in a statement.
Researchers said younger men who took more micronutrients didn't improve their sperm DNA.
The study was published Monday in the online issue of the journal Fertility and Sterility.
