Toxicological studies so far suggest that excessive use of malathion, an organophosphate insecticide, causes serious ill-effects in mammalian reproductive physiology. The present study aims at assessing malathion-induced toxicity in a dose- and time-dependent manner with mitigating effects of N-acetyl-l-cysteine. The testicular germ cell viability was monitored using MTT assay, where NAC, being an antioxidant significantly reduced malathion-induced toxicity by enhancing the frequency of cell viability. The histomorphological analysis showed that NAC successfully diminished several apoptotic features in testicular cells, induced by malathion. The differential EB/AO staining revealed a significant decline in the percentage of apoptosis after NAC supplementation. NAC also diminished the malathion-induced DNA fragmentation along with significantly reduction in oxidative stress parameters causing decrease in lipid peroxidation and enhancement of ferric reducing antioxidant power within testicular germ cells. Thus, NAC mitigated the malathion-induced toxicity, proving its potential in infertility treatment.
