Dads-to-be: Diet changes to boost your fertility
By the BabyCenter editorial staff

Why diet matters

Nutrition has a direct impact on the potency of your sperm. Research shows that poor eating habits and regular consumption of alcohol, for instance, can lower the quality and quantity of sperm, making conception more difficult. And since infertility is nearly as much a man's issue as a woman's — up to 40 percent of fertility problems can be traced to men — eating healthfully now will boost your chances of conceiving a child.

Conception isn't the only reason to revamp your diet. Additional research shows that dads who drink heavily — the equivalent of two drinks a day — during the month prior to conception have babies who weigh on average 6.5 ounces less than other babies. Low birth weight is a serious medical condition that can affect your child's health and behavior for the rest of his life.

Which nutrients are most important?

Your diet should be every bit as balanced, varied, and nutritious as your partner's. Specifically, future dads should:

• Eat plenty of foods rich in vitamin C and other antioxidants: They help prevent sperm defects and boost its motility (movement). An eight-ounce glass of orange juice contains 124 milligrams. Aim for at least 60 mg of vitamin C daily, more — at least 100 mg — if you smoke.

• Get more zinc in your diet. Several studies show that even short-term zinc deficiencies can reduce semen volume and testosterone levels. Great sources to help you get the 15 mg you need a day include oysters (six medium oysters have a whopping 76.3 mg), extra-lean ground beef (a three-ounce serving has 4.5 mg), baked beans (a one-cup serving has 3.55 mg), and dark chicken meat (2.38 mg per three ounces).

• Fuel up on folic acid. Studies suggest that men with low levels of this key B vitamin — the same one women need to reduce the risk of neural tube birth defects — have low sperm counts. You may be able to get the amount you need (400 micrograms a day) from fortified breakfast cereals, leafy greens, legumes, and orange juice, but just to be sure, it can't hurt to take a folic acid supplement or a multivitamin.

• Increase your intake of calcium and vitamin D. Infertility researchers at the University of Wisconsin at Madison suggest that consuming 1,000 mg of calcium and 10 micrograms of vitamin D each day may improve men's fertility. Good sources of calcium include low-fat milk (an eight-ounce glass has 414 mg) and yogurt (one cup has 302 mg of calcium). You'll find vitamin D in milk (an eight-ounce glass has two mcg) and salmon (a three-ounce serving has eight mcg).

• Cut out or cut back on alcohol. While an occasional drink is generally considered safe, studies show that daily consumption of wine, beer, or hard liquor can decrease testosterone levels and sperm counts and increase the number of abnormal sperm in your ejaculate.
