<i>Panax Ginseng</i> Protects Against Doxorubicin-Induced Testicular Injury in Male Rats by Modulating NF-κB/COX-2 and AR Pathways

Panax ginseng (PG) is a medicinal plant used for many years to treat many diseases. The current study aimed to investigate the possible prophylactic and therapeutic effects of PG extract on doxorubicin (DOX)-induced testicular toxicity in rats. 32 adult male Sprague-Dawley rats (200-250 g) were used in the experiment. The experimental groups were designed as control (normal saline, intraperitoneal), DOX (18 mg/kg, intraperitoneal), PG (200 mg/kg, gavage), and PG + DOX (200 mg/kg, gavage). After treatment, serum levels of testosterone, interleukin-1 beta (IL-1 beta), glutathione (GSH), luteinizing hormone (LH), superoxide dismutase (SOD), lactate dehydrogenase (LDH), catalase (CAT), follicle stimulating hormone (FSH), tumor necrosis factor-alpha (TNF-alpha), and malondialdehyde (MDA) were measured. Then, gene expression, histopathological, and immunohistochemical analyses were performed on testicular tissues. Compared to DOX, treatment with PG + DOX showed a significant improvement in serum levels of FSH, testosterone, LH, TNF-alpha, IL-1 beta, MDA, SOD, LDH, GSH, and CAT. It was also observed that PG + DOX decreased nuclear factor-kappa B and cyclooxygenase-2 expression levels, increased androgen receptor expression, restored testicular histopathological structure, and significantly improved spermatogenesis. The results of the present study showed that PG may have an ameliorative effect against DOX-induced male reproductive toxicity, as DOX causes male reproductive toxicity. It can be concluded that PG is one of the effects that protect against DOX-induced testicular toxicity in rats by reducing lipid peroxidation and activating the antioxidant system. In light of this information, PG may be a useful agent to prevent the testicular toxicity observed in men receiving DOX treatment.
