These beta-adrenoceptors couple to ion channels via specific signal transduction pathways, indicating that beta-blockers modify ion conductance across the membrane, thereby influencing calcium and potassium conductance (39)

This means that many supplement products reach the market without independent clinical scrutiny

These compounds induce excessive ROS production by depleting antioxidants, activating enzymatic ROS-generating systems (e.g., NADPH oxidase), and triggering mitochondrial dysfunction, ultimately impairing spermatogenesis and sperm quality ( Figure 1g ) ( Despite their diverse origins, both endogenous and exogenous factors converge on a common pathogenic pathway: by inducing mitochondrial dysfunction, activating enzymatic ROS-producing systems, or impairing antioxidant defenses, they lead to excessive ROS accumulation

Nitric oxide switches on glycolysis through the AMP protein kinase and 6-phosphofructo-2-kinase pathway
