OBJECTIVE: To investigate the effect of desferrioxamine (DFX) on ipsilateral and contralateral testis damage caused by experimental testis torsion and detorsion.
MATERIALS AND METHODS: Forty rats were divided into five groups (n = 8): control, torsion (T), torsion + desferrioxamine (T + DFX), torsion/detorsion (T/D), and torsion/detorsion + desferrioxamine (T/D + DFX). The right testes of the rats were subjected to torsion and detorsion for 3 h each. Thirty minutes before the application of torsion and detorsion, DFX (100 mg/kg) was administered intramuscularly. Blood samples and testicular tissues were examined using specific biochemical and histopathological methods.
RESULTS: Ipsilateral and contralateral testis tissue glutathione levels in the T group decreased compared with the control and T + DFX groups. Plasma glutathione peroxidase activity in the T, T/D, and T/D + DFX groups was lower than in the control group. Plasma catalase activity in the T and T/D groups decreased compared with the control group. Ipsilateral mean seminiferous tubule diameter of the T group was lower than that of the T + DFX group. The ipsilateral mean testis biopsy scores in the T and T/D groups were lower than in the control group.
CONCLUSION: The administration of DFX prior to torsion may be useful only for preventing ischemic damage in ipsilateral and contralateral testes.
