Abstract

Background

The present study was done to investigate the ameliorative effect of silymarin (SMN) and celecoxib (CEL) on varicocele (VCL)-induced detrimental impact in testicular tissue.

Methods

Mature Wistar rats were divided into control and test groups. Following VCL induction, the animals in test group were subdivided into non-treated VCL-induced, SMN-treated (50 mg/kg, orally), CEL-treated (10 mg/kg) and SMN + CEL-treated groups. Following 60 days, testicular total antioxidant capacity (TAC), malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase (SOD), glutathione peroxidase (GSH-px), total thiol molecules (TTM), mRNA and protein levels of COX2 and mRNA level of iNos were analyzed. Moreover, the germinal cells apoptosis and mRNA damage were examined.

Results

Observations revealed that co-administration of SMN and CEL significantly (P < 0.05) up-regulated TAC, SOD, GSH-px and TTM levels and resulted in a remarkable (P < 0.05) reduction in iNos and COX2 expression, NO and MDA contents. The animals in SMN + CEL-treated group exhibited significantly (P < 0.05) lower number of apoptotic cells and cells with mRNA damage per one mm2.

Conclusion

The SMN by up-regulating testicular TAC, SOD, GSH-px and TTM levels and the CEL by inhibiting COX2 and iNos expression as well as NO content could fairly ameliorate the VCL-decreased spermatogenesis.
