Abstract

Despite the prompt diagnosis and treatment of testicular torsion (TT), there are problems with fertility and atrophy after testicular salvage. Dexpanthenol (Dxp) is the biologically active alcohol of pantothenic acid (PA). Dxp is converted to PA in tissues. PA increases the content of reduced glutathione (GSH), Coenzyme A and ATP synthesis in cells. GSH and glutathione-dependent peroxidases (GPX) are the major defense systems against oxidative stress. GPX-4 is the major antioxidant in testicular tissue. However, the activity of GPX-4 appeared and increased only after puberty. We investigated the effect of Dxp on testicular atrophy after TT at the 60th day. Rats were separated randomly into four groups. Group C: control group, group Td: torsion + detorsion, group Sal: torsion + saline + detorsion, group Dxp: torsion + Dxp + detorsion. The left testis was rotated 720° for 2 h. In group Sal, normal saline and in group Dxp, Dexpanthenol were injected intraperitonally, 30 min before detorsion. After 60 days, the testicular weights and volumes were measured. Histopathology of the left testis was evaluated with mean seminiferous tubular diameter (MSTD) and mean testicular biopsy score (MTBS). The left (torsed) testicular weight and volume of groups Td and Sal were significantly lower compared to group Dxp. The MSTD and MTBS of group Td and Sal were significantly lower than group Dxp. Contralateral testicular weight and volume of groups Td, Sal and Dxp had no significant difference compared to the control group. Dxp significantly prevented testicular atrophy after 60 days of TT. Dxp has FDA approval, is safe, cost effective and readily available. Its relevance for clinical trials may especially be for the problem of testicular atrophy catastrophe, seen very frequently following testicular salvage.
