Protective role of melatonin against testicular damage caused by polymicrobial sepsis in adult rats

Abstract

BACKGROUND: This study aimed to investigate the possible protective effects of melatonin (MEL) against the damage to testicular tissue in rats caused by polymicrobial sepsis as a result of cecal ligation and perforation (CLP). METHODS: In this study, 21 male Wistar albino rats were used. The rats were randomly divided into three groups (n=7): Sham Control (Group 1), CLP (Group 2), and CLP + MEL (Group 3). Sepsis was created using the CLP method. MEL was administered intraperitoneally in two equal doses of 10 mg/kg at 30 min before and 6 h after perforation. Tissue sections taken from paraffin blocks were stained with hematoxylin and eosin (H and E) and examined histopathologically under a light microscope. Intracellular H2O2 and apoptosis evaluations were carried out using the flow cytometric method. RESULTS: Sepsis caused a significant reduction in all sperm parameters. There was a significant decrease in sperm density, motility and cell numbers with normal morphology (p
