My fertility doctor never insisted that I cut anything out. I am a tea-aholic ... I probably drink 2-3 glasses a day. Before my IUI (when I got prego with my daughter), I hadn't cut it out at all. In fact, I was drinking a Tea when they called me with my BETA results. Eek. Of course, once I knew I was prego for real, I cut it out completely for 9 months.
Yet, after doing some research, caffeine does affect fertility IF consumed in HIGH amounts.
What exactly constitutes a "high amount?" In Dr. Gray's study, anything over 300 milligrams per day, which is the equivalent to about two 8-ounce cups of drip-brewed coffee, four 8-ounce cups of tea (hot or iced), nine caffeinated sodas, or 15 ounces of dark chocolate.
I probably should cut mine back to 1 or 2 cups daily .... and decaf still contains 4-20mg of caffeine. I know there is some conflict if Herbal Tea is okay during pregnancy.
I loved Hibiscus tea when I was prego. Totally an acquired taste, but I loved it with a muffin
