Foods to Boost—or Bust—Fertility
Fertility Booster: Fish
The omega-3 fatty acid DHA (docosahexaenoic acid), found in oily fish, may help improve sperm quality, suggests a study in the Journal of Lipid Research. University of Illinois researchers found that mice lacking a gene necessary to convert alpha-linolenic acid (ALA) into the long-chain omega-3 DHA that promotes brain function and heart health appeared to be infertile. “They produced a low sperm count (10% of the norm) and these sperm have an abnormal shape that doesn’t move,” says author Manabu T. Nakamura, D.V.M., Ph.D. Supplementing their diets with DHA reversed these abnormalities. It’s still too early to make recommendations for how many omega-3s men should aim to get, says Nakamura, but any amount is likely to be helpful.
