Abstract (original English)

Purpose This study aimed to examine the therapeutic effects of injection of conditioned medium of adipose-derived mesenchymal stem cells (ADMSC-CM) in a surgically created varicocele model in comparison with varicocelectomy. Materials and methods Twenty-eight male Wistar Albino rats were randomly divided into four groups: sham group, varicocele group, varicocelectomy group, and ADMSC-CM injection group. Sperm parameters were analyzed in samples taken from the epididymis after treatment. Malondialdehyde and superoxide dismutase (SOD) levels in blood samples were examined by biochemical analysis. The testicular tissues were stained with hematoxylin-eosin for histological examination (Johnsen's Score). Additionally, Western Blot analyzes were performed to detect Claudin-11 levels, the functional protein of the blood-testis barrier, in testicular tissues. Results Varicocelectomy and ADMSC-CM treatments significantly improved mean sperm parameters (concentration, progressive motility, motility, normal sperm morphology) (p≤0.05 for all). Both treatment groups had increased SOD levels along with a decrease in malondialdehyde levels (p≤0.05 for all). No significant difference was observed between the ADMSC-CM group and the varicocelectomy group in preserving normal testicular histology according to Johnsen's Score (p=0.114). Levels of Claudin-11 were significantly higher in the varicoc
