The European Food Safety Authority (EFSA) recommends that women who are trying to conceive, as well as pregnant women, keep their daily caffeine intake below 200 mg, while the World Health Organization (WHO) recommends a daily caffeine intake of less than 300 mg. Caffeine is a central component of coffee, but it is also found in other foods such as tea, soft drinks, chocolate, energy drinks, and some medications.
Although there are not many studies, it seems that the consumption of 100-300 mg of caffeine per day does not affect the chances of getting pregnant in women undergoing assisted reproductive treatment, but it is associated with a reduced number of eggs during egg retrieval. In case of pregnancy, consumption of >100-200mg per day is associated with an increased risk of miscarriage.
In men, caffeine intake can also negatively affect fertility. It seems that consuming more than 4 cups of coffee per day can damage the morphology of sperm, while the ability to fertilize is reduced with consumption of more than 3 cups per day. The caffeine that comes from cola drinks seems to have a more harmful effect.
Try to consume 1-2 coffees per day, with 1 teaspoon of coffee!
Choose coffees with a lower caffeine content per serving, such as Greek or espresso!
