Caffeine and Infertility: Does the Cup of Joe Need to Go?

Is the connection between caffeine and infertility real? For those who are trying to get pregnant, the idea that you might need to forgo your morning pick-me-up can be daunting. So what is the truth about caffeine’s link to fertility?

Check out our FAQ guide:

Are caffeine and infertility linked?

Maybe. Published studies have drawn different conclusions. For example, one study found that women who had more than 300mg per day, which is the equivalent of two 8-ounce cups of coffee or nine caffeinated sodas, had a 27% lower chance of conceiving than women who had no caffeine.

However, a Spanish study found that caffeinated stimulants didn’t affect a woman’s fertility until she ingested more than 500mgs a day. Another 2008 review of several fertility/caffeine studies concluded that low to moderate caffeine consumption (less than 300mgs per day) did not reduce a woman’s chance of conception.

Does caffeine affect a man’s fertility?

While a few small studies suggest that caffeine affects sperm in a laboratory setting, there is currently no strong evidence that links caffeine and infertility in men. In fact, at least one study suggests that caffeine actually boosts sperm’s ability to propel itself all the way to the egg.

Is coffee the only thing I need to cut back on?

Unfortunately, no. Caffeine hides in many of our favorite foods and drinks, such as energy drinks, teas, and soft drinks. Chocoholics will also be disappointed to learn that their favorite treat also contains caffeine. Also be wary of herbal supplements and medications that contain the stimulant.

Do I need to go cold turkey?

No! When it comes to caffeine, many reproductive specialists say that it is safe as long as you don’t overdo it: keep consumption to less than 200mg each day. That means you’ll want to stick to one 8oz-cup of joe or 2 soft drinks each day.

Here are a few simple—and doable—strategies for reducing your caffeine fix:

* Start mixing decaf with your regular brew. Gradually decrease the amount of regular coffee until you’re eventually drinking all decaf.

* Switch to caffeine-free sodas and/or teas. You might also try carbonated waters, which give you the fizz of soda without the caffeine jolt.

* Add more milk to your coffee than you normally would. Your body will benefit from less caffeine and more calcium.

What’s the final word on how caffeine affects fertility?

They may be linked. No doubt, future science will give us a definitive answer. Until then, whether you choose to reduce your caffeine intake or cut it out entirely, you can be sure you’re giving your body the best chance for conception by being aware of the potential connection between caffeine and infertility.
