Abstract

AIMS:

One of the most common urologic emergencies is spermatic cord torsion, which can damage testicular tissue and reduce fertility. Salvia miltiorrhiza (SM) hydroalcoholic extract possess high antioxidant properties, and its efficacy in ischemia-reperfusion (I/R) injury prevention has been demonstrated in cardiac, renal, and liver tissues. Therefore, the purpose of this study was to assess the protective mechanism of SM extract on testicular I/R damage.

MAIN METHODS:

18 mature male Wistar albino rats were randomly divided into 3 groups; with six rats in each group: Group 1 (Sham) was sham-operated. Group 2 (T-D): torsion was performed, and after 2 hours (h) detorsion was done. Group 3 (SM): (200 mg kg-1) SM was intraperitoneally injected thirty minutes before detorsion. Then testicular and epididymal weight and size alterations, sperm parameters (motility, livability, concentration, and morphology), both plasma and testicular tissue levels of malondialdehyde (MDA), catalase (CAT), glutathione peroxidase (GPX), and total antioxidant capacity (TAC) were evaluated. Also, histopathological changes included mean seminiferous tubular diameter (MSTD), testicular capsule thickness (TCT), mean testicular biopsy scoring (MTBS), and germinal epithelial cell thickness (GECT) were examined.

RESULTS:

Testicular I/R significantly reduced sperm motility, viability, and normality, while SM extract administration remarkably increased sperm motility, and normality (P < 0.05). Induction of testicular T-D caused a significant increment in the level of MDA and notable decline in the levels of GPX, CAT, and TAC both in plasma and testis tissue, whereas administration of SM extract significantly decreased MDA level and increased GPX, CAT, and TAC levels in plasma and testicular tissue (P < 0.05). Histopathological parameters including MSTD, GECT, MTBS, and TCT were significantly lower in the T-D group, while pretreatment with SM extract remarkably increased MSTD, GECT, and MTBS amounts (P < 0.05).

CONCLUSION:

Since the SM extract increased the activity of antioxidant enzymes, improved sperm parameters and reduced the damage to testicular tissue, therefore, its use as a potent antioxidant in reducing testicular I/R damage is suggested.
