(ANN ARBOR, Mich.) -- A new study suggests polychlorinated biphenyls (PCBs) may affect in vitro fertilization (IVF), according to HealthDay.
Congress banned PCBs in 1979, although the toxic chemicals can still be found in the United States, particularly in seafood and dairy. Environmental Health Perspectives published a report by the University of Michigan School of Public Health in their Feb. 24 issue, which indicated that PCBs could be the cause of a significantly lower IVF birth rate.
765 women were involved in the study. Scientists analyzed blood samples for PCBs, and found that the 530 cases who lost their babies, either by implantation failure or miscarriage, tended to have higher a PCB content.
The analysts said the findings do not necessarily apply to all infertility problems.
