According to a new study from the American Society for Reproductive Medicine, high levels of bisphenol-A may raise the risk of miscarriage in women already prone to them. Dr. Ruth Lathi studied 115 newly pregnant women with a history of infertility or miscarriage, and 68 had miscarriages and 47 had live births. When broken down into four groups based on BPA exposure levels, women in the top quarter had an 80 percent greater risk of miscarriage compared to those in the bottom group even though they were similar in age and other factors. However, Lathi cautions against interpreting the results too strongly, given the small sample size of the study.
