So can caffeine affect your fertility? Yes it can. Studies have shown that a high caffeine consumption (that’s around 5 cups per day of coffee) can contribute to decreased fertility in women. While the findings are not exactly clear on why this is the case, it’s worthwhile to lower your intake of coffee, tea, cola drinks and even chocolate while trying to conceive.
One particular study found that women who had more than 300 mg of caffeine per day had lowered their chances of getting pregnant by 27% compared to women who didn’t have any at all. However some other studies have shown no correlation at all between caffeine and fertility so it can be confusing to know who to believe.
You are going to have to decrease your caffeine levels anyway when you do get pregnant as it can affect the baby (and in some cases has been linked to miscarriage), so starting now is worthwhile for your health anyway.
