Experimental testicular torsion and its effects on the contralateral testicle

Abstract

In spite of some changes, definite evidence for contralateral damage due to ipsilateral torsion contributing to male infertility was hardly observed.

The protective effects of nitric oxide on the contralateral testis in prepubertal rats with unilateral testicular torsion

“…Tarhan et al [21] reviewed various animal studies (25 in all, conducted between 1975 and 1990) of the contralateral testis after UTT and reported that contralateral testicular damage was detected in 17 studies. Most studies over the last decade also suggest contralateral testicular damage after UTT [2,5,7,8,10,20], although some do not [14,15,21].…”

“…Unilateral testicular torsion (UTT) is a common condition and may be associated with subsequent diminished fertility. There have been several recent clinical and experimental studies of contralateral testicular injury after UTT; most of these studies [1–12] reported contralateral testicular damage, with specific histological [1,3,9–11] and biochemical [5] changes after UTT, although others disagree [13–17]. Of the several proposed causes for such damage, a reflex decrease in contralateral testicular blood flow is probably the most likely [2,5,12,18].…”

Long-term effects of the testicular torsion on the spermatogenesis of the contralateral testis and the preventive value of the twisted testis orchiepididymectomy

“…It is well-established in the literature that testicular torsion causes early damage to the spermatogenesis of the contralateral testis [6][7][8][9] . However, there are few and conflicting results in the literature as to whether the testicular torsion causes permanent damage (long-term effects) to the spermatogenesis of the contralateral testis, and whether the orchiepididymectomy of the twisted testis could prevent this damage [10][11][12][13][14][15] .…”
