“…The contorted testis, however, does not appear to have an effect on the excretory function of the contralat eral testis either in the acute stage or at a later date. This corresponds with our immunologic studies [9], We did not find sperm antibodies in the sera of the patients con cerned. Since Anderson and Williamson [1] reported sim ilar results and did not find antitestis antibodies in their patients either, immunologic damage to the noncontorted testis by the contorted one seems unlikely.…”

“…In 1982 we were able to find in ultrastructural studies (semi-thin section, electron microscopy) of biopsy sam ples from the contralateral noncontorted testis -collected at the time of unilateral torsion -a preexistent distur bance of spermiogenesis at the level of spermatoblasts in all 7 cases that were examined [9], At that time we already suggested the possibility of the congenital bilateral testicu lar dysplasia responsible for extraordinary mobility and reduced fertility in patients with torsion of the testis. Anderson and Williamson [ 1 ] also reported similar results in 1986 and they concluded that immunologic factors are unimportant for the disturbed fertility after unilateral tor sion of the testis.…”

Fifty-five patients were followed up for their state of fertility at a time varying in length after testicular torsion. In addition to the spermiogram they were screened for sperm antibodies. Biopsy samples were collected from the contralateral (not contorted) testis in 34 patients at the time of torsion or immediately afterwards. Two to 8 years after torsion only 7 out of 55 patients had a normal spermiogram. Nineteen had an OAT syndrome, 10 had asthenospermia and 19 had teratospermia. Sperm antibodies occurred very rarely at the time of torsion (2/36) or at the time of a further checkup (2/36). Immunological damage to the noncontorted testis by the contorted one seems therefore rather unlikely. Histology of the contralateral testis, the samples of which were taken at the time of torsion (30) or up to 4 months later (4), showed pathological conditions in 30/34 cases (desquamation of the germinative epithelium, atrophy of the Leydig cells, malformation of spermatoblasts) and normal spermiogenesis in 4 cases only. Hence, a preexistent congenital testicular dysplasia must be assumed to be the cause of the observed disturbance of spermiogenesis and reduced fertility.

“…Horica et al [21] poses the question whether these alterations which occur at the time of the torsion are eith er congenital or due to subclinical torsions. Neither lightmicroscopic nor ultrastructural findings determine a dis tinction between dysgenesia and testicular subtorsions.…”

“…As Horica [21] has stated, biopsies should be per formed in small children who present with testicular pain of short development but, nevertheless, in clinical prac tice, this is very difficult to carry out. The ages of the chil dren included in our study were between 3 and 7.5 years.…”
