In this study, we investigated the time‐course changes of hormone levels and sperm numbers in male Sprague–Dawley (SD) rats after neonatal exposure to 3,3′,4,4′,5,5′‐hexachlorobiphenyl (PCB169). Neonatal rats were given (through oral gavages) doses of 0, 0.025, 0.25, or 0.5 mg/kg‐day of PCB169 in corn oil from postnatal day 1 (PND1) to PND7. The rats were sacrificed at PND8, PND21, and PND90. PCB169...
