Combined Effects of Chrysin Supplementation and Exercise Training on Diabetes-Induced Oxidative Stress and Apoptosis in Rat Testicular Tissue.

Background: Diabetes mellitus (DM), one of the most pervasive and enduring metabolic diseases, has been demonstrated to adversely impact male fertility. Conversely, both exercise training and Chrysin have been identified as potential interventions capable of mitigating the deleterious effects of diabetes on spermatogenesis. Thus, the current study aims to explore the individual and combined influences of Chrysin supplementation and running exercise on oxidative stress and germ cell apoptosis in the testicular tissue of diabetic adult rats.

Tramadol Influences Cellular Metabolism and Autophagy in Germ and Sertoli Cells; Exercise Training as A Potential Ameliorative Strategy.

Objective: Dysregulation of lipid and carbohydrate/fatty acid (FA) balance in Sertoli and germ cells alters the NADP+/ NADPH ratio, resulting in metabolic autophagy in testicles. Tramadol (TRA) adversely affects spermatogenesis development, and it is not reversed within short periods of time after withdrawal. Therefore, the present study aimed to examine the boosting effect of different exercise training protocols (ETPs) on TRA-induced detrimental effects after withdrawal.
