Abstract
Background: Troxerutin is a flavonoid antioxidant that protect different organ
against damage caused by ischemia-reperfusion.
Objective: The aim of this study was to evaluate the effect of troxerutin in reducing
the damages caused by ischemia-reperfusion in rat's testis.
Materials and Methods: 40 Male Wistar rats (2 month old) were divide to four
groups (n=10). Group1 (sham), Group 2 (control, ischemia-reperfusion (I/R) without
treatment), Group 3 (I/R+150 mg/kg of troxerutin), and group 4 (I/R+20 mg/kg of
vitamin C). Treatment of group 3 and group 4 during torsion (twists 720 counter
clock at 90 min) followed by 50 days detorsion. After 50 days, blood samples were
collected and rats in all study groups were killed and their testes were removed, and
fixed with Bouin’s solution. Testis was stained with hematoxylin and eosin dye and
the level of testosterone, luteinizing hormone (LH) and follicle-stimulating hormone
(FSH) were measured with ELISEA methods. TUNEL was employed to detect
apoptosis. Epididymis caudal part was removed and total sperm count was
determined. Johnson techniques were used for assessment of seminiferous tubules
quality.
Results: Troxerutin treated group has higher Johnson score’s (p≤0.001),
antiapoptotic properties (p≤0.001), sperm count (p=0.065), and higher LH
(p≤0.001), FSH (p≤0.001) and testosterone (p=0.002) levels than control group.
Vitamin C treated group showed increase level of testosterone but didn’t show
significant differences on the number of apoptotic cells, Johnson scores, LH, FSH
and sperm count than control group.
Conclusion: Troxerutin has protective effects on testicular torsion induced injury
and can ameliorate spermatogenesis in the torsion-detorsion models.
