Fig. 1. Testicular torsion is managed by either orchiectomy or orchiopexy. Detorsion during orchiopexy may cause reperfusion injury and combined with ischemic damage due to arterial constriction spermatogenesis might be altered resulting in reduced sperm concentration, reduced motility and reduced morphologically normal sperm. Studies have also demonstrated a negative impact of testicular torsion on the contralateral testis. This has been hypothesized to be caused by the formation of anti-sperm antibodies (ASA) and contralateral vasoconstriction resulting in hypoxia and subsequent reperfusion damage.
