[Polychlorinated biphenyls as a cause of sterility in women?]

A total of 59 female infertile patients were investigated for the concentration of polychlorinated biphenyls (PCB) in their blood serum and follicular fluid. The average concentration of PCB in 66 related samples of follicular fluid and blood serum was 1.6 and 1.8 ng/ml, respectively. A splitting of the patients into two collectives, one with explained infertility, the other with unexplained infertility, showed no evidence of a higher PCB concentration in unexplained infertility patients. These results may exclude PCB as a primary reason for unexplained infertility.
