Caffeine: Does it affect your fertility?
Does caffeine affect fertility?
It might. Some studies have found a link between caffeine consumption and a woman's ability to conceive, while others have not. Most experts say there just isn't enough evidence to make a definite conclusion about caffeine and fertility.
Although researchers haven't been able to find a clear connection between moderate caffeine intake and fertility problems, it's generally considered safe to consume 200 to 300 milligrams (mg) of caffeine daily while trying to conceive. That's up to two 8-ounce cups of coffee for a weak brew. If you get more than that, it might be a good idea to cut back.
Which foods and beverages contain caffeine?
Coffee is one, of course. The amount of caffeine in a serving of coffee varies widely, depending on the type of bean, how it's roasted, how it's brewed – and, obviously, on the size of the coffee cup. (For example, espresso contains more caffeine per ounce, but it's served in a tiny cup. So a full cup of brewed coffee will actually deliver more caffeine.)
To manage your caffeine intake, you'll need to be aware of other sources, like tea, soft drinks, energy drinks, chocolate, and coffee ice cream. Caffeine also shows up in herbal products and over-the-counter drugs, including some headache, cold, and allergy remedies. Read labels carefully.

How can I cut back on caffeine?
If you decide to drink less caffeine, cut back slowly to avoid withdrawal symptoms, such as fatigue and headaches.
You might want to start by switching to a drink that's half regular brew and half decaf. Or reduce the caffeine in homemade hot beverages by watering them down or brewing them for a shorter time. If you love to start your day with a cup of English Breakfast tea, steeping your tea bag for one minute instead of five reduces the caffeine by as much as half.
Once you've acclimated to life with little or no caffeine, you may find steamed milk with a shot of flavored syrup to be a nice coffee substitute – and the calcium will do you good.
