RESUMEN
The aim of the research was to study the effects of pentoxifylline on the sperm motility. Thirty samples of semen were studied. Each sample was divided into two sub-samples swim up technique. The other sub-samples were mixed with 3.3 mmol pentoxifylline solution for thirty minutes before entering the process of the sperm swim up preparation. The data regarding sperm concentration, motility, and morphology after 5 minutes of the swim up were recorded. The study showed that the samples that were mixed with 3.3 mmol pentoxifylline had a significantly higher sperm concentration (p< 0.001), greater sperm motility (p = 0.014), and a more normal sperm morphology (p < 0.001) than those samples prepared using the conventional method. It was concluded that pentoxifylline added in the process of sperm preparation could improve the sperm quality outcome.
