A new study shows that people who drank three or more cups a day of caffeinated drinks while trying for a pregnancy — sodas, energy drinks or coffee — were more likely to lose that pregnancy early on, Today.com reported. That was the case for men or women. And if women consumed more caffeine after they conceived, they were also more likely to miscarry, the study found.
The study, led by the National Institute of Child Health and Human Development, is one of the most detailed yet to look at the connection between caffeine intake and pregnancy loss. It is also one of the first to note that men's caffeine consumption affects fertility.
The study found that women who took multivitamins before they got pregnant and early in pregnancy were 50 percent less likely to miscarry.
The 344 couples in Texas and Michigan watched for the study wrote down every caffeinated drink they had, every serving of fish, every alcoholic drink, were weighed regularly, and gave urine, blood, saliva and semen samples. The women took regular pregnancy tests.
