Background  This study tested the hypothesis that combined melatonin (Mel) and adipose-derived mesenchymal stem cells (ADMSCs) treatment was superior to either one alone on protecting the testis against acute testicular torsion-induced ischemia-reperfusion (TTIR) injury.    Methods and results  Male adult SD rats (n = 30) were equally categorized into group 1 (sham-operated control), group 2 [TTIR/by torsion of right/left testis (i.e., ischemia) with rotated 720° counterclockwise for 2 h, then detorsion (i.e., reperfusion) to the original position for 72 h], group 3 (TTIR + Mel/intraperitoneal administration/50 mg/kg at 30 min after ischemia, followed by 20 mg at 3 h and days 1/2/3 after TTIR), group 4 (TTIR + ADMSCs/1.2 × 10 6  cells/by tail-vein administration at 30 min after ischemia, followed by days 1/2 TTIR), and group 5 (TTIR + Mel + ADMSCs/tail-vein administration). The result showed that the protein expressions of oxidative-stress (NOX-1/NOX-2/oxidized-protein), apoptotic/mitochondrial-damaged (mitochondrial-Bax/cleaved-caspase3/cleaved-PARP/cytosolic-cytochrome C), and fibrotic (TGF-ß/Smad3) biomarkers as well as testicular damage scores were lowest in group 1, highest in group 2, and significantly higher in groups 3/4 than in group 5, but they showed no difference between groups 3/4, whereas the protein expressions of androgen receptor (AR) and vimentin showed an opposite pattern of oxidative stress (all p < 0.0001). The cellular levels of inflammation (MMP-9/MPO/CD68) exhibited an identical pattern, whereas the numbers of Sertoli cells, α-tubulin, AR and vimentin as well as thickness of seminiferous tubule exhibited an opposite pattern of oxidative stress among the groups (all p < 0.0001).    Conclusion  Mel-ADMSCs effectively protected the testis against TTIR injury.
