There is no one magic food that will lure sperm to egg. Practicing all around good nutrition however, can help. The more natural your diet the better of you'll be. Think bright reds, yellows and greens for fertility-boosting foods. While trying to conceive, be sure to consume lots of calcium, a mineral vital for mom and her baby-to-be. To fill dietary gaps both mom and dad need to take a daily multivitamin. Never take more than the recommended dose.There are also some foods and drinks you should avoid. Alcohol decreases fertility in women and studies have shown that it increases the amount of abnormal sperm produced by men. Also, cut back on the caffeine. More than 300 milligrams, or three cups of coffee, daily can decrease fertility and even trigger a miscarriage.
