The question of drinking before and during fertility treatment tends to bring out strong opinions. It also comes up a lot with our Ovally customers: “Can I have at least a little Spanish wine during treatment?”. For the purpose of this post, we are going to focus on alcohol consumption before and during fertility treatment until conception only, and leave out any research on pregnancy and alcohol. As usual, check with your doctor on their guidance regarding alcohol intake during any fertility treatment. We’re summarizing the findings of high-quality research studies for you, but your doctor may have access to relevant, yet to be published findings.
Does drinking coffee or tea affect fertility?
“Can I have caffeine before and during my treatment?” is a great question we’ve gotten from our egg freezing and IVF Ovally customers. As is so often the case, the research on this question isn’t as clean and clear-cut as we’d like: It’s hard to separate out variables besides caffeine that can affect fertility outcomes, and many studies rely on retrospective self-reports of consumption, which can be unreliable. However, high-quality studies looking at a relationship between caffeine consumption and the ability to conceive during IVF treatment suggest that 1-2 cups of coffee per day don’t significantly affect the ability to conceive. Surprisingly, however, 1-2 cups of coffee a day (or the equivalent level of caffeine in another drink) have been found to double the risk of miscarriage during pregnancy.
