12 Things Men Can Do To Boost Their Fertility

Watch your weight

“The healthier the body, the healthier the sperm,” says Jamin Brahmbhatt, MD, co-director of the PUR Clinic in Clermont, FL. A study by Harvard School of Public Health found that overweight men were 11 percent more likely to have a low sperm count and 39 percent more likely to have no sperm at all in their ejaculate than normal-weight men. The news was even worse for men who were obese; they were 42 percent more likely to have a low sperm count and 81 percent more likely to produce no sperm than men at a normal weight. These are surprising facts about fertility OB-GYNs wish you knew.

Ditch the cigarettes

Smoking doesn’t just affect your lungs, it can also impact your fertility. “Smoking is known to affect our sperm count, motion, and general health of sperm. Tobacco metabolites can even be found in semen,” says Edmund Sabanegh, MD, director of the Center for Male Fertility at Cleveland Clinic in Cleveland, Ohio. The good news: Sperm health seems to bounce back relatively quickly once men quit. Learn techniques to break the habit for good.

Get enough sleep

It’s important to use your bed for more than just sex when you’re trying to make a baby. A study at Boston University School of Public Health followed nearly 800 couples who were trying to conceive and found that men who slept less than six hours and more than nine hours a night had a 42 percent lower probability of getting their partners pregnant than men who slept seven to eight hours each night. Researchers believe hormones are likely to blame for the lower chance of pregnancy; testosterone is crucial for sperm production and most of it is produced when men are asleep. Watch out for these everyday things that can hard your fertility.

Test your sperm

Women often track their ovulation at home to determine the small window each month when they have the greatest chance of conceiving. Now, men can monitor something of their very own, right alongside them: sperm. Trak Male Fertility Testing System is a new FDA-approved at-home test where men can measure their sperm count. A corresponding app then allows them to track their daily habits (eating, sleep, exercise, etc.) to determine how those factors may be affecting their sperm health. “A lot of couples keep trying and never know until they finally see a specialist what’s going on. This way, they can start checking for stuff at home and make changes through the help of the app before they even see a doctor,” says Dr. Brahmbhatt. While the Trak system isn’t meant to replace the help of fertility specialists should your sperm count come back low (a small device uses centrifugal force to isolate the sperm from your semen sample and rates the count on a three-tiered scale of low, moderate, optimal), Dr. Brahmbhatt says that it usually takes at least three months to see a change in sperm quality after making necessary lifestyle adjustments, so checking things out at home first can get the ball rolling in the right direction.

Limit your caffeine consumption

You and your mommy-to-be should both limit caffeine intake when you’re prepping for baby. A study in Nutrition Journal found that drinking more than four cups of coffee a day results in a higher proportion of abnormally shaped sperm. More research needs to be done to determine the link. (Find out if you’ve built up a caffeine tolerance, and what you can do about it.)

Steer clear of heat

Heat can be damaging to the testicles, which are cooler than the rest of the body because they reside outside the body. “There’s a reason they have a slightly lower temperature than the rest of the body, they function better that way,” says Dr. Sabanegh. Avoid hot tubs or anything that heats up your pelvis area, like laptops or heat packs, he says. (Learn about the top infertility myths.)

Eat your veggies

Prepping for a baby is the time when it’s even more important to eat a healthy diet with plenty of fruits and vegetables. Not only does having enough vitamins and minerals contribute to overall sperm health, but researchers have also discovered that the antioxidants found in many types of produce is associated with better semen quality. “Just like eating French fries is bad for your heart, your testicles are an organ too, and they feed off the same nutrients that the rest of your body does,” says Dr. Brahmbhatt.

Get off the couch

Researchers at Harvard School of Public Health found that healthy young men who watched more than 20 hours of TV a week had a 44 percent lower sperm count than those who watched almost no TV. They also found that men who exercised for 15 or more hours a week had a 73 percent higher sperm count than those who got less than five hours of activity. “We seem to have better hormone levels when we exercise regularly and testosterone levels seem to be higher,” says Dr. Sabanegh. Regular exercise also helps maintain a healthy weight, another fertility factor.

Consider your alcohol and drug use

“Alcohol in high levels can lower fertility and hurt our liver, which affects hormone levels. Marijuana and other drugs like opiates also affect the hormones required in sperm production,” says Dr. Sabanegh. This is the surprisingly young age that male fertility drops 20%.

Keep an eye on blood pressure and cholesterol

High blood pressure and cholesterol can contribute to erectile dysfunction, which means it’ll be harder for you to contribute your necessary dose of sperm, but it can also hamper you and your partner’s chances of getting pregnant. One study, published in the Journal of Clinical Endocrinology and Metabolism found that couples who had collectively high cholesterol levels took the longest time to get pregnant. Saturated and trans fats can cause blood pressure and cholesterol levels to spike; learn how to lower your cholesterol by eating the right foods. Keep in mind that both high blood pressure and cholesterol are risk factors for general cardiovascular disease. If you have either or both, find ways to improve your diet and exercise so you can lower your risk.

Avoid testosterone supplements

If you’re taking testosterone supplements to bulk up at the gym, you might have to make do with natural muscle-building methods while you’re trying to conceive. “Testosterone supplements trick the body into thinking it’s getting enough of the hormone, so it stops making it itself and sperm count lowers to almost zero,” says Dr. Sabanegh. The good news: Once you stop taking supplements, sperm count bounces back. These are surprising reasons you’re having trouble getting pregnant.

Try to relax

“Stress is associated with lower fertility, possibly because of cortisol, but nobody knows for sure,” says Dr. Sabanegh. Researchers have discovered that men with high levels of perceived stress and stressful life events have lower concentrations of sperm in their semen and the sperm that was present was more likely to be misshapen or have impaired motility, although they stopped short of saying there was a causal effect. Watch out for these other ways stress may make you sick.
