Cisplatin (Cis) is an important chemotherapeutic agent used in cancer treatment. Males exposed to Cis were reported to exhibit testicular toxicity. Cis-induced testicular toxicity is mediated by oxidative stress, inflammation, testosterone inhibition and apoptosis. Accordingly, this study was conducted to evaluate the potential protective roles of infliximab (IFX), which is an anti- TNF-a agent, and of white tea (Camellia sinensis), which is known to possess antioxidant, anti-apoptotic, and anti-inflammatory effects, against Cis-induced testicular toxicity in rats. Rats were randomly assigned into five groups as follows: control group, Cisplatin (7 mg/kg) treatment group, Cisplatin (7 mg/kg) + infliximab (7 mg/kg) treatment group, cisplatin + white tea (WT) treatment group, and Cisplatin+ WT+IFX combined treatment group. In the present study, Cis exposure reduced the sperm count. It also increased testicular oxidative stress as well as the levels of inflammatory and apoptotic markers. Histopathological assays supported the biochemical findings. Treatment with IFX and/or WT restored testicular histology, preserved spermatogenesis, suppressed oxidative stress and apoptosis, and significantly ameliorated Cis-induced damage. It was concluded that white tea and infliximab could potentially serve as therapeutic options for the protection of testicular tissue against the harmful effects of Cis.
