ObjectiveTo compare the effects of intraepididymal quercetin (IE-QE) with those of intraperitoneal quercetin (IP-QE) on testicular torsion/detorsion (TD)-induced ischemia/reperfusion (IR) injury of the testes in an experimental rat model.MethodsTwenty-four rats were divided into 4 groups: sham (S), TD, TD treated with IP-QE, and TD treated with IE-QE. The IP-QE group received 20âmg/kg QE intraperitoneally, whereas the IE-QE group received quercetin (QE) epididymally. After surgically induced TD, sera and testicular tissues were obtained for the analysis of biochemical parameters including glutathione peroxidase (GPx), malondialdehyde, total antioxidant status, total oxidant status, oxidative stress index, histologic changes, and evaluation of germ cell apoptosis.ResultsThe oxidative stress index and oxidants (malondialdehyde and total oxidant status) were increased with a concomitant decrease in the antioxidants (GPx and total antioxidant status) in the TD group. Severe histopathological damage, indicated by low Johnsen scores and high testicular injury grades, and germ cell apoptosis were found in the TD group compared with the other groups. Rats treated with QE showed significantly less IR injury, with moderately altered biochemical parameters, histopathological damage, and germinal cell apoptosis compared with the TD group. Most importantly, we found no significant differences in the biochemical parameters, histopathological changes, and germinal cell apoptosis between the IP-QE and IE-QE groups.ConclusionIE-QE was comparable to IP-QE in the treatment of testicular TD. Local QE therapy should be considered as a new approach to treating testicular IR injury due to TD.
