Effect of Short-Term High Fat Diet Inducing Obesity on Hematological, Some Biochemical Parameters and Testicular Oxidative Stress in Male Rats
Obesity constitutes a health problem due to its increasing worldwide prevalence. Among the health detriments caused by obesity, reproduction is disrupted. Some studies have shown a relationship between obesity and infertility, but until now it remains controversial. The objective of the current work was to examine the effect of diet-induced obesity on blood parameters, liver and kidney function tests, lipid profile and testicular oxidative stress. For that purpose, Male rats were fed ad libitum with a standard diet (control group; n.= 15) and high fat diet (HFD group; n.= 15) for 6 weeks. Hematological parameters, urea, creatinine, albumin were similar between the two groups. Intergroup testosterone levels were also comparable. The high fat diet induced significant increase in serum triglycerides, cholesterol, low density lipoprotein and very low density lipoprotein cholesterol concentrations. This diet also increases significantly alanine aminotransferase and aspartate aminotransferase activities and decreased total protein level and high-density lipoprotein cholesterol concentration. Furthermore, HFD showed a significant increasing in malondialdehyde contents in testes and decreasing in superoxide dismutase activity, the results of this study concluded that short-term high fat diet affect on liver enzymes and causing oxidative stress in testes.
