Diabetes mellitus (DM) may lead to testicular-related infertility while Myristic acid (MA) is beneficial to lower hyperglycaemia. Thus, we hypothesized that MA could protect testes against hyperglycaemia-induced damage in DM. DM was induced in adult male rats by high-fat diet consumption for 12 weeks, accompanied by a single dose streptozotocin injection. Following DM confirmation, the rats were fed orally with 10 and 20 mg/kg body weight MA for 28 consecutive days. After completion of treatment, rats were sacrificed and blood, cauda epididymis and testes were harvested. Serum was separated, epididymal sperm was collected for analysis. Molecular studies of the testes were performed by qPCR, Western blotting and immunostaining. MA was found to protect the testes against oxidative stress via preventing the upregulation of RAGE, Keap1, and the downregulation of Nrf2, NQO1, HO1, SOD, CAT and GPx. MA also prevented increase in testicular inflammation and apoptosis, as indicated by low inflammatory (NF-κB p65, IKKβ, TNF-α, IL-1β and iNOS) and apoptosis (Bax and caspase-9), but high anti-apoptosis (Bcl-2) markers' levels. Besides, MA prevented the downregulation of testicular steroidogenic markers (3βHSD, 17βHSD, StAR, ARA-54 and CYP11A1). Sperm analysis revealed near normal sperm count, motility, viability, lower abnormal sperm morphology in diabetic rats received MA. MA also prevented the loss of germ cells via preventing the decreased in cell proliferative marker (PCNA) while maintaining near normal epithelial height, tubular and Leydig cell diameters in the testes in DM. MA protects the testes against damage in DM, thus maintaining spermatogenesis and steroidogenesis, consequently preserving male fertility in diabetes.
