PG - 4673-4680 LID - 10.1021/acs.est.7b00289 [doi] AB - We investigated testosterone production and semen parameters in farmed Arctic foxes by dietary exposure to persistent organic pollutants (POPs) for 22 months. Eight male foxes were given a diet of POP-contaminated minke whale blubber, whereas their eight male siblings were fed a control diet containing pig fat as the main fat source. The minke whale-based feed contained a summation operatorPOPs concentration of 802 ng/g ww, whereas the pig-based feed contained summation operatorPOPs of 24 ng/g ww. At the end of the experiment, summation operatorPOP concentrations in adipose tissue were 8856 +/- 2535 ng/g ww in the exposed foxes and 1264 +/- 539 ng/g ww in the control foxes. The exposed group had 45-64% significantly lower testosterone concentrations during their peak mating season compared to the controls (p
