Aim: The purpose of the present study was to investigate the changes of malondialdehyde (MDA), total antioxidant status (TAS), total oxidant status (TOS) levels; histopathological alterations; morphology, concentration and motilities of the sperm in post ischemic reperfused (I/R) testis tissue. Materials and Methods: Forty adult male Wistar rats were carried out and were randomized to five groups; (1) Control group, (2) Ipsilateral left testis ischemia, (3) Melatonin plus ipsilateral left testis ischemia, (4) Contra lateral right testis ischemia, 5. Melatonin plus contralateral right testis ischemia. After 1 h ischemia and 24 h perfusion; MDA, TAS and TOS levels were measured, histopathological alterations were determined using by Johnsen's score (JS) and sperm morphology, concentration, motility were examined. Results: MDA,TAS and TOS levels of the testis tissue did not change in all groups (p > 0.05 for all). JS was decreased in I/R group and melatonin treatment reversed histopathological changes and increased JS both in ipsilateral and contralateral testis. Abnormal sperm rate significantly increased in I/R group and melatonin administration changed abnormal sperm rate to normal. Conclusions: As a result, the present study demonstrated that testicular damage occurs following I/R without an increase of MDA, TAS and TOS levels. Our results also suggested that melatonin is a potent antioxidant agent in preventing testicular I/R injury, as shown by increased JS and changed abnormal sperm rate.eninfo:eu-repo/semantics/closedAccessIschemia-reperfusionMelatoninTestisOxidative stressJohnsen's scoreEffects of melatonin on testis histology, oxidative stress and spermatogenesis after experimental testis ischemia-reperfusion in ratsArticle16558258822774397Q2WOS:000305663400003Q4
