The aim of this study was to analyse the effect of pirfenidone against ischaemia–reperfusion injury occurring after detorsion in rats with induced testicular torsion model. Group 1 was assigned as the control group. Group 2 first had testis torsion performed, and then, testicular detorsion was performed. Group 3 had similar procedures to the rats in Group 2. Rats in Group 3 additionally had 325 mg/kg pirfenidone administered immediately after ischaemia. The blood samples were analysed spectrophotometrically. To determine the intensity of tissue injury, haemorrhage, oedema and congestion levels were evaluated with direct microscopic investigation of testis. Seminiferous tubule architecture, spermatogenesis processes and germ cell maturation were graded by Johnsen and Cosentino scoring systems. In Group 3, superoxide dismutase (SOD) and glutathione peroxidase (GSH‐Px) activities increased compared with Group 2 ( p :.03 and p :.049 respectively). Additionally, the mean malondialdehyde (MDA) value was higher in Group 2 compared with the other groups ( p :.001). Histopathological investigation of rats in Group 3 identified positive changes in haemorrhage, oedema and congestion levels compared with Group 2 ( p :.031, p :.048, p :.044 respectively). Similarly, Johnsen and Cosentino scores were positively affected in Group 3 ( p :.033, p :.032 respectively). Pirfenidone is protective against testicular oxidative damage.
