Endocrine disruptors: Manmade and natural oestrogens: opposite effects on assisted reproduction, Nature Reviews Endocrinology, 18 March 2016.
In a new study, a dramatic decrease in the frequency of implantation, pregnancy and live birth is associated with increased urine levels of Bisphenol-A (BPA) in women undergoing in vitro fertilization (IVF). However, in women who consume soy-containing foods, the interfering effect of BPA on IVF success is negated.
“The findings by Chavarro and colleagues show that the probability of having a surviving embryo goes from more than 50 percent to under 20 percent as levels of BPA increase. … … . As findings continue to mount and confirm that daily exposure to BPA is a reproductive toxicant, it becomes vital to regulate and control this chemical.”
