    OBJECTIVE: To study prospectively experimental effects of unilateral epididymal obstruction on testis and epididymis histopathologically in prepubertal rats. STUDY DESIGN: Organ weights, mean seminiferous tubule diameter (MSTD), mean ductus epididymis diameter (MDED), mean tubular biopsy scores (MTBS) and histopathology of 21 male albino Wistar rats were compared with the immunostaining affinity of antidesmin, anti-vimentin, anti-laminin and anti-collagen antibodies. RESULTS: Statistical analysis of mean weight of testes, MTBS, mean epididymal weight, MDED and MSTD was significant. Evaluation of testis and epididymis revealed cellular damage, basal membrane impairment and granulomatous infiltration. CONCLUSION: Histopathologic alterations with MSTD are early indicators for ipsilateral and contralateral injury. Even the presence of criteria such as intactness and cellular integrity does not guarantee there is no sperm leakage or immunologic damage. Therefore the impairment of basal integrity is a switch code in determining spermatogenic failure.
