We investigated histological changes in the contralateral testis and epididymis and proliferative potential of constituent cells of the contralateral testis and epididymis by silver staining of argyrophilic nuclear organizer regions (Ag-NORs) after unilateral testicular torsion (UTT). Fifty adult male rats were divided into 5 groups each containing 10 rats. Torsion operations were performed by rotating the left testes 720° in a clockwise direction. Torsion duration was 1, 4, 12 and 24 hrs that was lied in group 1 to group 4, respectively. Then, de-torsion operations were performed and 24 hrs. Later, histopathological changes in the contralateral testes and epididymis were investigated and compared to group 5(control). Control group underwent a sham operation of the left testis. In histologic examination, Johnson’s scores of right testes in group 3 and group 4 were different from other groups (P<0.001). In all groups, histological changes in the contralateral testes and epididymis were observed. Also, there was no significant difference in subjective Ag-NOR pattern assessment for constituent cells in the right testes and epididymis between different groups (P>0.05). Our findings demonstrate that UTT results in contralateral testicular and epididymis damage but no the quantitative changes in the rapidity of cell proliferation in cytohistological preparations.
