Antioxidants tied to older men's sperm quality: Study

(REUTERS)- Middle-aged and older men who get enough antioxidants in their diets, through eating foods such as broccoli and tomatoes, may have better-quality sperm than men who don't get as much of the nutrients, according to a United States study.
Researchers found that among men aged 45 or older, those who got the most vitamins C and E, folate and zinc tended to have fewer DNA-strand breaks in their sperm, according to a report in the journal Fertility & Sterility.
Strand breaks are a measure of the genetic quality of sperm, which is known to decline as a man ages, though the findings do not prove that antioxidants themselves directly improve sperm quality or boost the chance of a healthy pregnancy.
"People who eat well are probably doing a bunch of other healthy things too," said senior researcher Andrew Wyrobek, of the Lawrence Berkeley National Laboratory in California.
