In this study, because of the anti‐inflammatory and antioxidant effect of the Ziziphus jujuba (ZJ), we assessed the protective properties of the ZJ extract against testis toxicity caused by Adriamycin in the rat. Twenty rats were grouped into (a) control, (b) Adriamycin, (c) ZJ group and (d) treatment group in which Adriamycin was administrated and the ZJ hydroalcoholic extract was used for three weeks. On the 21st day, two testes were removed to determine the oxidation markers and pathological evaluation. The levels of sex hormones were determined. Epididymis also was crushed, and its spermatozoa were evaluated as concentration, motility and normality. Adriamycin increased oxidative stress markers as well as Luteinising hormone, and follicle‐stimulating hormone and decreased testosterone levels compared to control. In the treated group, the levels of the above markers improved. The decreased number and motility of spermatozoa in treatment group increased, and the increased rate of abnormal spermatozoa in this group decreased. Pathological evaluations also show the healing process of damaged testicular tissue in the group receiving the ZJ extract. The ZJ extract relatively improves oxidative stress, sperm characteristics, hormonal alternation and pathological changes. These findings reveal the probable role of ZJ effective compounds in repairing tissue damage.
