Women's fertility levels can be negatively impacted by consuming a lot of caffeine, it has been suggested.
Some expatriate health insurance customers might want to discuss the issue with their doctor if they are planning a family.
The research, which was conducted by a team from the University of Nevada School of Medicine, revealed that high caffeine intake hinders muscle activity in the fallopian tubes.
Since it is this activity that helps move eggs from the ovaries to the womb, consuming too much caffeine can be problematic.
Professor Sean Ward, who worked on the report, commented: "As well as potentially helping women who are finding it difficult to get pregnant, a better understanding of the way fallopian tubes work will help doctors treat pelvic inflammation and sexually-transmitted disease more successfully."
While the research was conducted on mice, Professor Ward suggested that the findings certainly go some way to explaining why human females with a high caffeine intake have a lower likelihood of becoming pregnant.
