Background: Platelet –Rich Plasma (PRP) is a novel therapeutic agent used in multiple medical fields and one of these fields is the reproduction for best spermatozoa preparation and activation for upgrading activity and motility of the spermatozoa and filtered with glass wool filtration to eliminate any round cells and leukocytes from the sample. Objectives: The aim of this research is to study some sperm characteristics in two groups, the normozoospermic infertile men and th asthenozoospermic infertile group before and after activation with Glass wool Filtration and PRP and compare between both. Patients and Methods: In this study 60 infertile men were enrolled and divided into 2 groups,15 normozoospermic infertile men, and 45 ashenozoospermic infertile men during their attendance to the Infertility Clinic in High Institute for Infertility Diagnosis and Assisted Reproductive Technologies Al-Nahrain University. The collected semen samples, and seminal fluid analysis were assessed, each semen sample was divided into 3 tubes and labelled as the 1st tube which was before activation, the 2nd tube was after glass wool filtration activation technique and the 3rd tube was for semen activated by adding PRP to the medium used for glass wool filtration activation. Results: Both techniques showed increased and improved sperm motility, but the PRP was superior to the glass wool alone in upgrading Sperm Grade A Motility %, Sperm Grade B Motility % and decreasing Sperm Grade C Motility %, and Sperm Grade D Motility (Immotile Sperm). Conclusion: The PRP was significantly effective in improving the sperm activity and upgrading sperm motility more than Glass Wool Filtration technique.
