Is There a Relationship Caffeine and Risk of Infertility?

Some experts recommend that the effects of caffeine consumption of less than 200 milligrams is not too problematic for women who are trying to conceive.

A question often arise in the minds of the women who are trying to conceive, that if the content of caffeine in a cup of coffee or tea can affect their fertility?

The possibility of a link between caffeine, fertility, and the rate of miscarriage is still a debate among scientists. To get some idea about the relationship between caffeine and fertility, it helps if you listen to quote a reference that has been trusted and become a benchmark by many physicians and patients the following:

  1. About 20 percent of American adults consume more than 300 mg of caffeine per day. Several studies have reported that increased consumption of caffeine (more than 300-500 mg) is still relatively moderate, but statistically this has led to significant fertility penuruanan. Consumption of large amounts of caffeine can have a major contribution to fertility problems. The Site March of Dimes recommends that women trying to become pregnant should not consume more than 200 milligrams of caffeine per day.
  2. How does the caffeine in triggering infertility remains unclear. It is not known whether the consumption of caffeine can also increase the production of estrogen or estrogen actually lowers your metabolism. There is even an opinion, caffeine consumption was associated with infertility due to tubal factor and endometriosis-related infertility. Most research conducted on coffee drinkers do not take into account other sources of caffeine that may affect fertility.
  3. There is no evidence that caffeine consumption by men or husbands will affect fertility. Effect of caffeine on the success of in vitro fertilization (IVF) has not proven because there is still lack of research.

Based on the above study, experts concluded that the effect of caffeine on reducing the fertility rate remains unclear. While several other studies showing the effects of caffeine on fertility have absolutely no effect.

Although the study did not find the allegedly caffeine entirely on fertility, but decreased levels of caffeine intake may be a good idea.

Caffeine, Endometriosis, and Estrogen

Several studies have found that caffeine can affect estrogen levels, especially leading to higher circulating levels. Previous research found that women caffeine drinkers who are struggling to conceive, may be more likely to have endometriosis, rather than other causes of infertility. Due to the high levels of estrogen can make endometriosis worse. So, if you have endometriosis, you may need to consider more mature again to reduce caffeine intake.


Numerous studies have so far found no association between the effect of caffeine on reducing fertility in men, although this is still not clearly evident in women. Some experts recommend that the effects of caffeine consumption of less than 200 milligrams are not be too problematic for women who are trying to conceive. Amount of 200 milligrams of caffeine equivalent of about two cups of coffee.
