Aim of the current study was to investigate the ability of deltamethrin to induce testicular injury in rats and its possible attenuation with lycopene. Rats were divided into three groups: Group I (DEL) received deltamethrin, 5 mg/kg b.w./day orally, in corn oil. Group II (DEL + Lyc) received oral dose of lycopene (4 mg/kg b.w./day) in corn oil concurrently with deltamethrin following the same regimen as in group I. Group III (Control) received appropriate volume of corn oil. After 4 weeks, deltamethrin-treated rats showed decreased body weight, serum testosterone, luteinizing hormone and follicle-stimulating hormone levels. Testicular total oxidant capacity (TOC), nitrite/nitrate (NOx), poly (ADP-ribose) polymerase (PARP), and DNA damage were significantly increased. RT-PCR demonstrated significant up-regulation in testicular mRNA for glutathione-S-transferase and heat-shock protein-70 (HSP-70), whereas steroidogenic acute regulatory (StAR) protein was down-regulated after deltamethrin exposure. Lycopene was able to restore body weight, serum testosterone, StAR mRNA, TOC, NOx levels, and PARP activity with significant decrease in HSP-70 mRNA, and DNA damage. In conclusion, lycopene was able to counteract the deleterious effect of deltamethrin.
