[Intervention effect of Modified Dahuang Zhechong Granule on epididymal morphological changes in experimental varicocele rats].

Objective: To explore the effect of Modified Dahuang Zhechong Granule (MDZG) on the development and maturation of epididymal sperm in experimental varicocele (VC) rats.

Methods: Sixty SD male rats were randomly divided into six groups of equal number, sham operation, VC model, Aescuven forte, and low-, medium- and high-dose MDZG. The model of left VC was made by the Turner method in all the rats except those of the sham operation group, followed by treatment with 0.
