The consumption of caffeine in excess brings various problems and it is possible that it has some incidence on fertility. Although the available data is not confirmed.

  • It is said to reduce the chance of conceiving
  • Let’s start by saying that there is research stating that caffeine consumption affects fertility. However, there are also studies that suggest the opposite. It is not easy to come to a definitive conclusion.
  • It should be noted, in any case, that a healthy lifestyle is one of the central pillars of fertility. Therefore, regulating caffeine consumption would be a good idea when someone decides to have a child.
  • The initial study on caffeine and fertility women who drank a daily cup of coffee halved their chances of conceiving
  • On the other hand, research led by Dr. Rosemarie Hakim, from the Hopkins Hospital School of Medicine in Baltimore (United States), indicated that there was a significant association between the consumption of more than 3 cups of coffee per day and a reduction in fertility by 26%.
  • caffeine consumption reduced muscle activity in the fallopian tubes
  • Other experts point out that caffeine consumption does not seem to have caused any effect in couples trying to conceive through assisted fertility treatments. It neither made those processes more difficult nor slowed them down.

Findings and controversies

  • The available studies on the relationship between caffeine consumption and fertility are not as extensive as one would like. Several experts question these findings, since aspects such as the following are overlooked:
  • The studies, in many cases, are based on volunteer reports or recollections . This gives rise to data that cannot be fully corroborated .
    There is no certainty that it was the coffee and not some other substance that caused the reduced fertility or problems during pregnancy. There was no way to control what the volunteers consumed.
  • The investigations cannot attest to the doses that each one of the volunteers consumes . A cup of coffee at home may have more or less caffeine than one in a public place.
    The consumption of caffeine in large amounts is common in people who suffer from fatigue. At the same time, fatigue could be a manifestation of some underlying disease, including endometriosis or depression. These conditions do alter fertility.
  • How much coffee is enough?

If a woman wants to have children, it is best to consume 100 milligrams or less of coffee per day.

The problem is that data on how much caffeine is in an 8-ounce cup of coffee, which is the average, is not always readily available. The basic indicators would be the following:

  • 1 cup of ground coffee: between 55 and 150 milligrams of caffeine.
  • 1 cup of regular instant coffee: between 27 and 173 milligrams.
  • 1 2-ounce cup of espresso: 47 to 75 milligrams.
  • 1 cup of decaffeinated coffee: between 1 and 25 milligrams.
  • 1 cup of decaffeinated instant coffee: 2 to 12 milligrams.
