    Unilateral testicular torsion can cause lasting damage to the opposite testicle, especially in adults. Early intervention is crucial to prevent long-term fertility issues and testicular damage.

    Area of Science:

    • Urology
    • Reproductive Medicine
    • Immunology

    Background:

    • Unilateral testicular torsion can lead to contralateral testicular damage.
    • This damage may be immunologically mediated and potentially preventable.

    Purpose of the Study:

    • To investigate the temporal effects of unilateral testicular torsion on the contralateral testis.
    • To assess the impact of torsion duration and age at torsion on testicular alterations and fertility.

    Main Methods:

    • Studied the effects of prepubertal torsion in rats.
    • Utilized deoxyribonucleic acid (DNA) histograms to evaluate spermatogenesis in adult rats after varying torsion durations.
    • Assessed the persistence of contralateral testicular alterations and fertility rates up to 6 months post-torsion.

    Main Results:

    • Prepubertal torsion did not result in contralateral testicular alterations.
    • Torsion exceeding 8 hours in adult rats led to significant contralateral testicular damage, evidenced by DNA histograms in 60-80% of animals.
    • Contralateral testicular alterations persisted for 6 months, with significantly reduced fertility rates.

    Conclusions:

    • The duration of unilateral testicular torsion is critical in determining contralateral testicular damage.
    • Adult rats are susceptible to long-term contralateral testicular damage and fertility impairment following prolonged torsion.
    • Prepubertal torsion appears to have a protective effect on the contralateral testis.
