[The establishment of testicular fibrosis model in Wistar rats].

Objectives: To establish the testicular fibrosis model in rats.

Methods: Wistar rats were divided into control group(n = 12) and model group(n = 40) randomly. Testicular fibrosis model was built with the classical method of establishing experimental autoimmune orchitis (EAO) combined with injecting Bacille Calmette-Guerin (BCG) into left testis.
