This study aimed to assess the possible protective effects of naftidrofuryl (Naf) against methotrexate (MTX)-induced testicular toxicity in rats. Male rats were randomly distributed into four groups: control, Naf, MTX, and MTX+Naf groups. MTX administration induced oxidative stress, inflammation, and apoptosis in the testicular tissue, while pretreatment with Naf attenuated these pathways. Naf pretreatment significantly decreased malondialdehyde and interleukin-6 contents, microRNA-29a (miRNA-29a) expression level, and nuclear factor kappa B and p53 immunostaining in the testicular tissues compared to the MTX group. Conversely, it significantly increased Johnsen's score, serum testosterone level, serum total antioxidant capacity, testicular superoxide dismutase activity, testicular catalase activity, and testicular cell division cycle 42 (CDC42) expression compared to the MTX group. In conclusion, Naf exerted a significant protective effect against MTX-induced testicular toxicity via antioxidant and anti-inflammatory mechanisms and modulating the p53/miRNA-29a/CDC42 apoptotic pathway.
