Objective: To investigate the effect of nifedipine on testicular torsion-detorsion injury.
Materials And Methods: Twenty-four adult male Sprague-Dawley rats were randomly divided into 3 groups, each containing 8 rats. Rats in the control group underwent a sham operation of the left testis. In the torsion-detorsion (T/D) group, the left testis was twisted at 720° for 3 hours. After 3 hours of reperfusion, at the end of the experiment, the testes were removed. Rats in the treatment group received the same surgical procedure as the T/D group, but nifedipine was administered intraperitoneally (100 μg/kg) 30 minutes before the time of detorsion.
Results: Unilateral testicular torsion-detorsion caused a significant increase in the malondialdehyde level and apoptosis and caused significant decreases in superoxide dismutase and glutathione peroxidase activities in ipsilateral testes. The rats treated with nifedipine had a significant decrease in malondialdehyde level and apoptosis and had significant increases in superoxide dismutase and glutathione peroxidase activities in ipsilateral testes compared with those of the T/D group.
Conclusion: These results suggest that biochemical and histological torsion-detorsion injury occurs in the ipsilateral testes after a 3-hour torsion and 3-hour detorsion and that administration of nifedipine before detorsion prevents ischemia/reperfusion cellular damage in the testicular tissue.

Background: Testicular torsion is a critical urological emergency that can lead to testicular ischemia and significant tissue damage. Citrulline, a supplement known for enhancing cellular metabolism and mitigating oxidative stress and inflammation, has been explored for its protective effects against testicular injury resulting from torsion and detorsion in rat models.
Methods: This study involved 42 Wistar rats, divided into six groups: Sham, torsion/detorsion (T/D), and four groups receiving varying doses of Citrulline (300, 600, 900 ) and vitamin E (20 ).

Testicular ischemia-reperfusion (I/R) injury during testicular torsion is strongly influenced by oxidative stress caused by excessive accumulation of unscavenged reactive oxygen species. This study aimed to investigate the effects of intra-peritoneal administration of Mito-TEMPO (MT) on I/R injury in testicular torsion/detorsion (T/D) in mice. Forty-two male mice were divided into seven groups including 1 control and 6 treatment groups (360° T/D, 720° T/D, 360° T/D + 0.

Background: Testicular torsion-detorsion damage is a common ischemia-reperfusion injury brought on by an excess of reactive oxygen species. Reactive oxygen species may affect cellular differentiation by regulating gene expression. The gene expression in the testis is essential for spermatogenesis.

Testicular ischemia-reperfusion induces enhanced concentration of reactive oxygen species. The increased reactive oxygen species harm cellular lipids, nucleic acids, proteins, and carbohydrates, and ultimately cause testicular injury. Sulforaphane, a kind of natural dietary isothiocyanate, exists predominantly in some cruciferous vegetables, like broccoli and cabbage.
