Women trying to get pregnant may be able to improve their chances by cutting back on coffee, researchers at Johns Hopkins University suggest. The team reported in the American Journal of Epidemiology that women who consume more than 300 milligrams of caffeine a day--roughly three cups of coffee or eight sodas--reduce their monthly chance of conception 26%.
No effect was seen in women consuming less than 300 milligrams. “On average, a couple has a 20% chance of getting a viable pregnancy each month,” said Dr. Ronald Gray of Hopkins. “The high caffeine drinkers would reduce that by a quarter. It would be around 15%.”
