Caffeine has been a part of many people’s daily lives for over a century now. Whether it comes in coffee, tea, cappuccino or soda pop, many people either can’t or don’t want to limit their caffeine intake. While research has shown negative effects of an overabundance of caffeine in pregnant women, does caffeine affect your ability to get pregnant?

Some research has suggested that there is a connection between high caffeine intake and a delay in conception. For purposes of one study, high caffeine intake” was defined as consuming more than 300 mg of caffeine per day. For another study, “high caffeine intake” was defined as consuming more than 500 mg of caffeine per day. A woman who is trying to conceive should limit her caffeine intake to no more than 300 mg per day.

Research has focused mainly on the woman’s caffeine intake; there have been fewer studies on the impact of caffeine on male fertility, and these studies have produced ambiguous results. They suggest that a man who naturally (or from some other cause) has a low sperm count may actually improve his sperm count by increasing his caffeine intake. However, there is some evidence to suggest that, for a man who naturally has a normal or high sperm count, that high caffeine intake may indeed reduce a man’s sperm count, making conception much more difficult.

Below are some common sources of caffeine and their amounts:
Brewed coffee, 8 ounces: 100-300 mg
Instant coffee, 8 ounces: 50-190 mg
Espresso, 2 ounces: 40-70 mg
Cappuccino, 12 ounces: 300-400 mg
Decaffeinated coffee, 8 ounces: 1-8 mg
Brewed tea, 8 ounces: 35-175 mg
Instant tea, 8 ounces: 40-80 mg
Diet Coke, 12 ounces: 45 mg
Mountain Dew, 12 ounces: 55 mg
Hot cocoa, 8 ounces: 3-30 mg
Milk chocolate, 1 ounce: 1-15 mg
Dark or semisweet chocolate, 1 ounce: 5-35 mg
Baker’s chocolate, 1 ounce: 26 mg

As you can see, the amount of caffeine in a give product can vary greatly. Fortunately, many companies list the amount of caffeine in their products, either on the product label or on their web sites. The above guide is best used when you do not have access to more specific information.”
