Abstract
Objective- Testicular torsion and detorsion are significant clinical issues for infertile man. Torsion of the spermatic cord is an emergency condition resulting from rotation of the testis and epididymis around the axis of the spermatic cord. A rat testis model was used to assess effects of polyethylene glycol on ischemia-reperfusion injury. Design- Experimental study Animals- Twenty four healthy male Wistar rats Procedures- The rats were included and randomized into four investigational groups (n = 6): Group SHAM: Merely laparotomy was implemented. Group ISCHEMIA: Merely a 3- hour interval ischemia was done. Group IS/REP: A 3-hour interval ischemia, three-hour reperfusion for left testis, one week reperfusion for right testis were done and 20 µL normal saline was administered intraperitoneally (IP) 30 min before termination of ischemia. Group IS/REP/PEG: The same as group IS/REP as well as 20 µL PEG solution 3% (IP) 30 min before termination of ischemia. Evaluations were based on biochemical analyses and sperm parameters morphometry. Results- Polyethylene glycol enhanced antioxidant activity and quality of sperm parameters (p<0.05). Conclusion and clinical relevance-Polyethylene glycol could be helpful in minimizing ischemia-reperfusion injury in testicular tissue exposed to ischemia
