Could coffee impair women's fertility?

31st May 2011

Questions have been raised over the effect that coffee can have on a women's fertility, after a study showed that it could have adverse effects.

Researchers from the University of Nevada School of Medicine found that caffeine affected fertility in some mice, which have a similar reproductive system to people, as it relaxed cells in the muscles of the fallopian tubes, which carry eggs from the ovaries to the womb.

Details were not provided on the level of caffeine which could lead to this inhibition of transportation, but the scientists said that the amount they were using in the tests was equivalent to around two cups of coffee a day for humans.

Study researcher Sean Ward said: "This provides an intriguing explanation as to why women with high caffeine consumption often take longer to conceive than women who do not consume caffeine."

The Telegraph reported that previous advice surrounding coffee and fertility said that even a moderate amount of coffee could impair a woman's ability to get pregnant.

Earlier this month a study was published suggesting that drinking coffee could reduce the risk of prostate cancer.
