Caffeine consumption may reduce a woman’s fertility

Caffeine is a drug – a nervous system stimulant – that is found not just in coffee, but in many other foods and beverages, such tea, chocolate, energy drinks, and some soft drinks (e.g., Coca Cola). Common side effects of caffeine consumption include increased heart rate, hyper-alertness, a rise in blood pressure, and higher metabolism. Among women, caffeine may also affect fertility. Caffeine has also been associated with changes in estradiol and other hormones, which may affect a woman’s menstrual cycle, ovulation, and the time it takes to achieve a pregnancy. There is also some evidence to suggest that caffeine consumption may increase the risk of miscarriage.

At this time the research findings demonstrating the relationship between caffeine consumption and women’s fertility are mixed. Some studies have reported a negative effect of caffeine consumption on women’s fertility, while others have found little effect. The picture may actually be more complex, with women whose fertility is already compromised being more negatively affected by caffeine consumption.

Overall, the available evidence suggests that mild to moderate consumption of caffeine does not lead to detrimental effects on women’s fertility. However, for women who are trying to get pregnant, experts recommend limiting caffeine consumption to no more than 100 – 200 mg per day (i.e., less than 2 cups of coffee per day). If you are planning a pregnancy, you may wish to consult with your doctor or fertility specialist about your caffeine consumption.
