In a very interesting new study, published online last week in the journal Fertility and Sterility, found that not only women who consumed more caffeine, but also their partners (men) who did, had a higher chance of miscarriage in the first trimester. For those whose partner drank more than three caffeinated drinks per day, their chance of miscarriage increased. The study was conducted on a controlled group of 344 heterosexual couples who were followed several weeks before and after they became pregnant. Although the study concluded that higher miscarriages were reported for those who consumed more caffeinated drinks, it cannot conclusively prove that one leads to the other.
