Testicular tissue and sex hormones are sensitive to the anabolic steroids (oxymetholone/OM) due to increased free radical damage and hormonal changes. The Nasturtium officinale L. have various antioxidant compounds. The aim of the present study was to investigate N. officinale effect on OM-induced oxidative injury in mouse testis and sperm parameters. Thirty BALB/c mice were divided into five groups, including control, OM (5 ml/kg) and three N. officinale doses (25, 50 and 100 mg/kg) + OM. At the end of the study (40 days), serum luteinising hormone (LH), follicle-stimulating hormone (FSH), testosterone, nitric oxide (NO) levels, ferric reducing ability of power (FRAP) and testis stereological factors were measured. The sperm parameters were evaluated. Liquid chromatography-electrospray ionisation-tandem mass spectrometry (LC-ESI/MS) analysis was yielded a fingerprint of N. officinale phenolic constituents. 100 mg/kg of N. officinale extract significantly reduced the serum level of testosterone and a significant increase in LH and FSH in comparison with the control group. This dose also significantly improved the stereological factors and sperm parameters. 50 and 100 mg/kg of N. officinale extract significantly increased the testis tissue FRAP levels, and 100 doses reduced the serum levels of NO. Fourteen compounds and 34 peaks were identified in the extract with LC-ESI/MS. Nasturtium officinale extract has protective effects against testicular toxicity caused by OM.
