Pentoxifylline is an oral supplement commonly used to improve blood flow in patients with circulation problems by decreasing the viscosity of blood. As a xan-thine derivative, pentoxifylline acts as a competitive nonselective phosphodiesterase inhibitor, thereby raising intracellular cAMP. It has also shown an anti-inflammatory effect in neutralizing ROS by controlling the release of superoxide anions [101, 102]. This presumably reduces the amount of OS by downregulating the body's ability to initiate an inflammatory response. Table 22.7 summarizes the most recent studies conducted with pentoxifylline on improving sperm parameters.
