Some studies have shown a link between caffeine consumption and infertility. For example, BabyCenter cites a study that found that women who ingested 300 mg or more of caffeine per day had a 27 percent lower chance of conceiving than those who consumed no caffeine. The American Pregnancy Association also says some studies show a possible link between high caffeine intake and delayed conception.
Significance
BabyCenter notes that caffeine's effect on fertility is not fully understood. A moderate intake of caffeine, which it defines as less than 300 mg a day, might not affect your chances of conception. But some research indicates consuming 200 mg or more of caffeine per day while you're pregnant increases your risk of miscarriage. Consequently, BabyCenter recommends reducing your caffeine intake now while you're trying to conceive. If you're not sure whether caffeine will affect you, discuss your situation with your health care provider.
Reducing Withdrawal Symptoms
One reason to give up caffeine now is it will take some time to wean yourself off it. People who drink caffeine regularly develop a physical dependence. If they suddenly stop drinking caffeine, they likely will experience headaches, grogginess and other negative side effects. Slowly reducing your caffeine intake now will minimize the effects of withdrawal later.
Expert Insight
Reducing or eliminating your intake while you're trying to conceive helps you get a head start on proper pregnancy nutrition. Caffeine use during pregnancy can inhibit nutrient intake, according to the American Pregnancy Association. It says caffeine reduces your body's ability to absorb iron and calcium, which you and your developing baby will need during the pregnancy.
Considerations
Cut back on your caffeine intake by reducing or eliminating from your diet coffee, tea, sodas, chocolate products, energy drinks and coffee ice cream. Some herbal products and over-the-counter drugs, such as headache, cold and allergy medications, also contain caffeine. The amount of caffeine these products provide varies widely, so check ingredients carefully. For example, an 8 oz. cup of generic brewed coffee could contain anywhere from 102 to 200 mg of caffeine depending on such factors as the type of beans and brewing methods used.
