PG - 758-63 AB - OBJECTIVE: To examine the effects of in utero and lactational exposure to a binary mixture of 3,3',4,4',5-pentachlorobiphenyl (PCB126) and 2,3',4,4',5-pentachlorobiphenyl (PCB118) on reproductive function in male rat offsprings. METHODS: Pregnant Sprague-Dawley rats were given the mixture by gavage with 0.096, 0.96, 4.8 microg toxic equivalency (TEQ)/kg on gestational day (GD) 15. The effects of mixture on F1 rats were observed. RESULTS: The male offspring in the 0.96 and 4.8 microg TEQ/kg groups showed significant inhibition of body weight gain, anogenital distance (AGD) and sperm counts. Mixtures at 4.8 microg TEQ/kg significantly reduced weights of accessory sex organs, but only prostate weight reduced at 0.96 microg TEQ/kg. There were no significant differences on serum testosterone. CONCLUSION: The results demonstrated that in utero and lactational exposure to the mixtures of PCB126 and PCB118 affected development of male offspring and impaired adult male offspring reproductive organs.
