Abstract
Sperm motility is an essentialselection criteria by embryologists at the time of intracytoplasmic sperm injection (ICSI). One method of testing sperm viability is to induce sperm motility by increasing cyclic adenosine monophosphate (cAMP) levels by treating a semen sample with phosphodiesterase inhibitors (PDEIs), such as theophylline and pentoxifylline. It explores the implications of PDEI in medical care, reflecting on its effects in clinical settingsand recognizing potential topics for future exploration. This analysis revealed that by incorporating stimulants that activate movements, the time it took to single out sperms was markedly reduced, and consequently, the sperms were safeguarded from a prolonged period of oxidative stress. Furthermore, theophylline was found to advance sperm motility, consequently resulting in several initially immobile spermatozoa displaying rapid progressive motility. Higher fertilization rate, cleavage rate, good quality embryos (grade I), and higher biochemical and clinical pregnancy rates were found with artificial sperm activation (ASA) using pentoxifylline and theophylline. This review emphasizes the need for more research to evaluate the drug's long-term safety and investigate the effects of theophylline and pentoxifylline on postfertilization parameters, such as embryo development, implantation, and pregnancy outcomes. These areas of investigation are important for understanding the complete impact of these agents and to ensure their safe and effective implementation in clinical practice.
