Pesticides are integral to modern agriculture and public health but pose significant risks to human and environmental health. This study investigates the impact of selected pesticides on male reproductive health via inhalation in an improvised chamber. Male Wistar rats were assigned to groups and exposed to individual pesticides and a combined mixture to determine lethal doses. Tissue samples from 54 rats were analyzed histologically and biochemically for effects on testes and epididymides, with measured serum testosterone and GSH levels. Sniper consistently showed the highest significant decrease in GSH levels across all exposure levels (p < 0.05). A significant dose-dependent relationship was observed in the recovery groups from 25% to 75% exposure (p < 0.05). Pesticide exposure led to a substantial decrease in serum testosterone levels in male Wistar rats at 25% (all pesticides, p < 0.05), 50% (DD Force, Sniper, Kerosene, Combined, p < 0.05), and 75% (DD Force, Industrial Camphor, Edible Camphor, Kerosene, p < 0.01) concentrations. Escalating damage in testicular and epididymal structures, with a more pronounced severity at higher exposure levels, including epithelial degeneration, Sertoli cell vacuolation, seminiferous tubule derangement, and ductal atrophy. Increased exposure to high doses of pesticides induces oxidative stress in male Wistar rats which could potentiate decreased testosterone levels and adversely impact the histological architecture of the testes and epididymides. Pesticide detoxifications are somewhat evident following withdrawal from the environmental insults. Significant and persistent damage occurred at higher levels, suggestive of substantial reproductive toxicity following exposure.
