Although you’ll be the one carrying the baby for those nine months, dad-to-be has an important role too — his sperm affects whether you’ll get pregnant at all and if the pregnancy will be healthy. To keep his boys in tip-top shape, he should make these changes.

Get His Weight in Check
Being underweight or overweight can have negative effects on a man’s sperm, and it can kill a couple’s sex life because weight problems can affect a man’s libido and performance. Sticking to a healthy diet that contains a good mix of fruits, vegetables, lean proteins, grains, and dairy, and fitting in physical activity on most days of the week can help him reach or maintain a healthy weight.

Get More Folate
Folic acid isn’t important just for moms-to-be. Men who had lower levels of folic acid in their diet had a higher rate of abnormal chromosomes in their sperm, according to a study by researchers at the University of California, Berkeley. When sperm with abnormal chromosomes fertilize an egg, it may result in miscarriage or birth defects. More than half of first-trimester miscarriages are caused by chromosomal abnormalities in the embryo. This doesn’t mean your guy has to take folic acid pills: A good multivitamin or foods that are high in folate, like beans, leafy green vegetables, whole grains, citrus fruits, and folate-enriched cereals, breads, and pastas, will help him get the recommended 400 milligrams of folic acid he needs daily.
Smoking cigarettes can cause low sperm counts and slow-moving sperm. To give his swimmers a boost, your guy should stop smoking. It’s better if he quits as soon as possible, but he should definitely aim to be smoke-free at least three months before you try to conceive. “Sperm production takes about three months, so any changes the man makes today won’t show up in the semen for at least three months,” says Suzanne Kavic, M.D., director of the division of reproductive endocrinology at Loyola University Health System.
He should nix marijuana or other illicit drugs too. “Sperm may be damaged by these drugs, and women are more likely to miscarry if their partners use recreational drugs like cocaine, marijuana, and any of the other typical amphetamines,” says Lisa Mazzullo, M.D., co-author of Before Your Pregnancy: A 90-Day Guide for Couples on How to Prepare for a Healthy Conception.
Can the Beer
He doesn’t have to give it up completely, but it’s a good idea for men to limit their alcohol intake if they hope to become a dad. Alcohol has been shown to reduce sperm production and cause sperm abnormalities. Dr. Kavic says one to two drinks a day is fine (as long as they’re normal-size servings!). Another reason he should dry out a bit: A lot of men don’t perform as well sexually when they’re inebriated, Dr. Kavic says.
See a Doc
A thorough checkup before trying to conceive will give him an overview of his health and fertility status. As in your pre-conception visit, he can expect discussions about his body mass index (BMI), any medications he uses, lifestyle factors that may affect fertility and pregnancy, any genetic disorders or history that may pose a risk to the future baby, and what he can do to ensure you have a healthy pregnancy. He will also be given any needed immunizations to help prevent him from passing on illnesses like chickenpox and the seasonal flu to you during pregnancy.
Cut Down on Caffeine
A study of Danish men found that sperm count and sperm concentration were slightly reduced in men who had a high soda and/or caffeine intake. Dr. Mazzullo says men should limit their caffeine consumption (that includes coffee, tea, chocolate, and energy drinks) to 300 milligrams a day (about three 6-ounce servings).
Blow Off Some Steam
Stress can increase abnormal sperm and reduce its concentration. Sleeping and eating well, exercising regularly to work off pent-up energy and tension, making time to hang out with his guy friends (or sit in front of the tube and do nothing!) and other activities that he finds enjoyable or relaxing can help keep his stress in check.
Check His Meds
Before you start trying to conceive, he should make a list of all the medications he takes — including prescriptions, over-the-counter drugs, vitamins, and herbal supplements — and check them with his doctor. Some medications can affect the quality or quantity of a man’s sperm. If he’s using a medication that could possibly interfere with your baby-making goals, his doctor should be able to recommend a more fertility-friendly alternative.
There’s a reason a male’s testicles hang outside of his body. “Sperm production has to take place at a certain temperature, and even our core body temperature is too hot, so the testicles are outside to keep cool,” explains Dr. Kavic. If your guy does something that overheats his testicles, it can interfere with sperm production. So he should limit the time he spends in hot tubs, saunas, and steam rooms. Dr. Mazzullo recommends that men keep it to 15 minutes, no more than twice a week.
He may want to change his laptop habits, too. Dr. Kavic says there’s a possibility that using a computer on his lap too often may cause genital warming that could possibly affect the sperm. His best bet? Keep the lap time to a minimum, invest in a laptop cooling pad, and use the laptop on a desk more often.
Stay Away from Toxins
If your guy works around a lot of chemicals and toxins, he needs to make sure they don’t do a number on his member. Toxic chemicals such as heavy metals, lead, and chemical solvents can increase the percentage of damaged sperm, so men who expect to conceive in the near future should try to avoid them. If his job places him around chemicals, he can limit his contact by wearing a face mask and protective clothing and always using proper ventilation.
