Effect of Caffeine on Women Fertility


    I have seen many women been faced with lot of questions, most of these women are those trying to get pregnant and the question is whether the caffeine in their early morning cup of coffee affects their fertility. Of a truth, there are news everywhere about connections between caffeine, fertility and pregnancy; let us examine whether caffeine actually affects women fertility.

    For us to pin out factual points about fertility and caffeine, there are some questions we need to ask and as well find answers to.

    How Much Caffeine Do We Have in a Cup of Coffee?

    Overtime, research on consumption of caffeine has focused solely on coffee drinkers and it is assumed that caffeine causes potential problem with coffee, meanwhile, it could be another substances that is found in coffee.

    That is that, but to play safe with caffeine, you would want to know that taking less than 200mg of caffeine a day is recommended, but I have come to realized that we tend to fix our caffeine in terms of cup rather than milligram.

    Talking of caffeine content in coffee, how about soft drinks? Here are some guidelines to follow.

    For coffee:

    • Drip (8 oz) = 234 mg
    • Percolated (8 oz) = 176 mg
    • Regular instant (8 oz) = 85 mg
    • Decaffeinated instant (8 oz) = 3 mg
    • Expresso (1 -2 oz) = 45 to 100 mg
    • Starbucks grande (16 oz) = 330 mg

    For tea:

    • 1 minute brew = 9 to 33 mg
    • 3 minute brew = 20 to 46 mg
    • Instant = 12 to 28 mg
    • Canned ice tea (12 ounces) = 22 to 36 mg

    For soft drinks:

    • Dr. Pepper = 39.6 mg
    • Regular cola = 46 mg
    • Diet cola = 46 mg

    For cocoa and chocolate:

    • Cocoa from mix (6 oz) = 10 mg
    • Milk chocolate (1 oz) = 6 mg
    • Baking chocolate (1 oz) = 35 mg

    Connection between Caffeine, Endometriosis and Estrogen

    Studies have shown that caffeine may have effect on estrogen level, leading to higher circulating levels. Some other studies found that for those under pressure to conceive, caffeine drinkers may be more prone to have endometriosis, as opposed to other causes of infertility.

    It is a good thing to get our body in tip-top shape when trying to get pregnant, and many has even made it their primary goal –taking coffee or tea in the morning, while many are still aiming to join the team, many had wanted to give it up because of the caffeine content and the fear of lowering their estrogen level.

    What does the research actually have to say about caffeine and fertility? Is there any reason to feel guilty over just one cup of coffee?

    Then, read on for what all of this means for you.

    “Approximately 20 percent of adult Americans consume greater than 300 mg of caffeine daily. Some studies have reported that increased caffeine consumption (e.g., >300 to 500 mg) is associated with a modest, but statistically significant decrease in fertility, while others have not found an adverse effect. The widespread consumption of caffeine at doses associated with sub fertility makes it a potentially important contributor to fertility problems. The March of Dimes website recommends that women who are trying to become pregnant consume no more than 200 mg of caffeine per day.

    “The mechanism by which caffeine consumption may be linked to infertility is unclear. Caffeine consumption may increase estrogen production and/or decrease estrogen metabolism. Caffeine consumption has also been linked to tubal factor infertility and endometriosis associated infertility. Most studies were done in coffee drinkers and do not account for other sources of caffeine or other substances in coffee that may affect fertility.

    “There is no strong evidence that caffeine consumption by the male partner influences fertility. Whether caffeine consumption impairs success of in vitro fertilization is unclear due to lack of studies.”

    Conclusion on Caffeine and Fertility

    Studies have not found a connection between caffeine and lowered fertility in men.

    While it’s not clear yet whether caffeine lowers fertility in women, the studies that have shown an effect find that less than 200 mg of caffeine should be ok. You don’t have to give up your morning cup of coffee and you don’t need to feel guilty about it, but you might want to pass on seconds.
