Changes in the histopathology of the testes with the epididymis were studied 3 months and 6 months after vasocclusion either with ethanol urea mixture or ethanol alone in male rats. A gradual decrease in the fertility of treated animals was observed. The epididymis showed tubules with sperm granuloma and the testis showed empty tubules with Leydig cell hyperplasia in the urea-ethanol treated animals.
