To explore the intervention and mechanism of YiqiBushen Tongluo Decoction（益气补肾通络方）in the treatment of varicocele infertility inmice.
A total of60 Sprague Dawley（SD）rats were selected and divided into sham operation group，model group，Yiqi Bushen Tongluo Decoction low dose group，medium dose group and high dose group according to random number table method，with 12 cases in each group.The drug was given by intragastric administration 48 h after the modeling was completed and continuously used for60 d.The testis and epididymis quality，sperm quality，spermatogenic cell apoptosis index and the levels of malondialdehyde（MDA），superoxide dismutase（SOD）and nitric oxide（NO）in testicular tissue were compared among all groups.
The testis quality，epididymal quality，sperm concentration and sperm motility in the model group were lower than those in the sham operation group，and the spermatogenic apoptosis index was higher than those in the sham operation group，with statistical significance（P<0.05）.Compared with those in the model group，the testis quality，epididymal quality，sperm concentration and sperm motility were significantly increased in the Yiqi Bushen Tongluo Decoction low dose，medium dose and high dose groups，and the spermatogenic apoptosis indexwas significantly decreased，with statistical significance（P<0.05）.The levels of MDA and NO in the model group were higher than those in the sham operation group，and the SOD level was lower than that in the sham operation group，with statistical significance（P<0.05）.Compared with those in the model group，the levels of MDA and NO were significantly decreased in the Yiqi Bushen Tongluo Decoction low dose，medium dose and high dose groups，and the SOD level was significantly increased，with statistical significance（P<0.05）.
Yiqi Bushen Tongluo Decoction can improve the sperm quality of mice with varicocele infertility.Itsmechanism of action is mainly related to inhibiting spermatogenic cell apoptosis，anti-oxidative stress and reducing NO level.
