Quantitative evaluation of testicular biopsies from men with unilateral torsion of spermatic cord.

Torsion of the spermatic cord is not uncommon among young men. Various abnormalities in the histology of the contralateral testis have been reported due to unilateral torsion of the spermatic cord. We quantitatively estimated the germ cells from three groups of men: normal individual (Group I), men with unilateral torsion of short duration (Group II), and men with unilateral torsion of long duration or some other condition such as varicocele or intermittent torsion to the contralateral testis (Group III). No significant difference in the number of spermatogonia, spermatocytes, and spermatids of Groups I and II patients was observed. This observation indicates that there was no pre-existing morphophysiologic defect in the testis of Group II patients. Severe damage in the contralateral testis was noted in Group III patients. This indicates that if a damaged testis is retained in the body for a long time, the contralateral testis may be affected. Contralateral testis may also be affected by intermittent torsion or varicocele.
