I know that caffeine is considered a no-no during ttc and pregnancy, but I never knew why until I bothered to google it and found this article: http://www.medicalnewstoday.com/releases/226218.php which I copied and pasted below. My relationship with coffee goes back to when I was just a kid–my Mom drank black coffee ALL DAY LONG, which may or may not be the secret to how she ran a home daycare AND my Dad’s business AND took care of everybody, including the cats and cockatiel. I started drinking coffee at age 16, when I developed a crush on a skateboarder I knew from school, who worked in his gay uncle’s short-order diner. The gay is inserted before uncle, because the uncle encouraged the artsy-angsty (LBGT) university-bound youth of our town to sit and sip coffee while they contemplated life and wrote poetry and made art, whereas the totally not gay misogynistic owner (who I ended up working for a couple years later) kicked all of these colorful artsy types out because
he didn’t like “their type” they would sit and drink coffee for hours without buying food–such a dick. I’m glad that I got to witness the diner in it’s pre-misogynistic era, and meet some of those amazing people; I was exposed to culture for the first time in my life (no offense to my parents). Oh, and the whole reason I went to the diner was to drool over this skateboarder I had a crush on. The most intimate I ever got with him though, was smoking my first blunt in the closet at the diner (don’t judge me) with him and two other people. But I digress. I went to the diner to begin my relationship with a boy, but instead I began my relationship with coffee (and ‘mary jane’) at the tender age of 16. I proceeded to spend countless hours having intense (caffeine-fueled) philosophical conversations with friends and strangers in coffee shops. I discovered Starbucks when I moved to Honolulu at age 21 (I’m really telling you too much but c’est la vie) and I have probably spent a semester’s tuition on their special brand of crack. My favorite wedding present was my (beloved) Keurig. I LOVE COFFEE. And the thing is, both of the cycles that I got pregnant, I was drinking coffee with abandon (although not as much as I did in college, good Lord I could easily drink 3 pots a day back then!) And I’ve also quit coffee for several cycles, and nothin’ happened. So, I googled (in vain) “coffee good for conception” and I got nothing. Nobody will tell you that coffee is good for conception and pregnancy. Au contraire, coffee is the problem, not the solution. But…I don’t think I’m ready to give up my morning cup at this time. Ask me again in a few days after I get that BFN. Paix
Caffeine reduces muscle activity in the Fallopian tubes that carry eggs from a woman’s ovaries to her womb. “Our experiments were conducted in mice, but this finding goes a long way towards explaining why drinking caffeinated drinks can reduce a woman’s chance of becoming pregnant,” says Professor Sean Ward from the University of Nevada School of Medicine, Reno, USA. Ward’s study is published today in the British Journal of Pharmacology.
Human eggs are microscopically small, but need to travel to a woman’s womb if she is going to have a successful pregnancy. Although the process is essential for a successful pregnancy, scientists know little about how eggs move through the muscular Fallopian tubes. It was generally assumed that tiny hair-like projections, called cilia, in the lining of the tubes, waft eggs along assisted by muscle contractions in the tube walls.
By studying tubes from mice, Professor Ward and his team discovered that caffeine stops the actions of specialised pacemaker cells in the wall of the tubes. These cells coordinate tube contractions so that when they are inhibited, eggs can’t move down the tubes. In fact these muscle contractions play a bigger role than the beating cilia in moving the egg towards the womb. “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,” says Professor Ward.
Discovering the link between caffeine consumption and reduced fertility has benefits. “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,” says Professor Ward. It could also increase our understanding of what causes ectopic pregnancy, an extremely painful and potentially life-threatening situation in which embryos get stuck and start developing inside a woman’s Fallopian tube.
