Abstract The current study was performed to assess the adverse effect of deltamethrin (DLM) on reproductive organs and fertility in male rats and to evaluate the protective role of vitamin E (VE) and selenium (Se) combination in alleviating the detrimental effect of DLM on male fertility. The lethal dose 50 (LD(50)) of DLM for male rats was estimated at 6 mg/kg bwt. Thirty male albino rats (10-weeks-old) were divided into three groups (10 rats each): Control group was injected subcutaneously with 2 ml/kg bwt saline twice weekly and was daily administered 2 ml distilled water intra-gastrically; DLM-treated group received 0.6 mg/kg bwt (1/10 LD(50)) DLM intra-gastrically once daily; DLM+VE/Se-treated group was injected subcutaneously with 1.2 mg/kg bwt Viteselen(®)15 (VE/Se) twice weekly with concurrent daily administration of 0.6 mg/kg bwt (1/10 LD(50)) DLM intra-gastrically. The experiment was conducted for 60 consecutive days. DLM caused a significant reduction in reproductive organs weights, sperm count, sperm motility percent, alive sperm percent, serum testosterone level and testicular reduced glutathione concentration (GSH). DLM-treated group showed a significant increase in sperm abnormalities and testicular malondialdehyde (MDA) concentrations. Histopathologically, DLM caused impairments in testes, epididymes and accessory sex glands. Conversely, treatment with VE/Se combination improved the reduction in the reproductive organs weights, sperm characteristics, DLM-induced oxidative damage of testes and the histopathological alterations of reproductive organs. Results indicate that DLM exerts significant harmful effects on male reproductive system and that the concurrent administration of VE/Se partly reduced the detrimental effects of DLM on male fertility.
