Caffeine interferes with fertility in women
Caffeine, a known stimulant, can cause rapid heart rate, nausea, anxiety and depression. Recent research shows that caffeine can make it harder for a woman to get pregnant.
By analysing fallopian tubes in mice, researchers found that caffeine interferes with muscle contractions that help eggs travel from the ovaries through the fallopian tubes and into the womb - a process critical for a successful pregnancy. Though the experiments were conducted in mice, the findings explain why drinking caffeinated drinks could reduce a woman's chance of becoming pregnant. 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 researchers noted that the study's findings could further the understanding and treatment of infertility as well as some complications of pregnancy. Previously, it was thought that eggs moved through the fallopian tubes assisted by hair-like projections called cilia, but this study suggests that specialised pacemaker cells coordinate the contractions that push the eggs along.
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 and understand what causes ectopic pregnancy.
