Do you drink a lot of coffee? Are you having a difficult time becoming pregnant? The two may be linked, according to research published last week in the British Journal of Pharmacology.
Researchers at the University of Nevada examined the link in mice and concluded that caffeine stymies specialized cells in the muscular walls of the fallopian tubes, which transport eggs from a woman’s ovaries to her uterus.
"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," Sean Ward, a professor in the School of Medicine at the University of Nevada, said in a press release.
Previous research linking caffeine and pregnancy rates and outcomes has been inconsistent.
Nevertheless, some medical officials advise to err on the side of caution. Women trying to get pregnant may benefit from limiting their daily caffeine intake.
