Swim up is the most popular technique of sperm preparation, in which sperm is selected on motility and ability to swim out the plasma of the semen. The goal of this research is to compare the influence of adding platelet rich plasma (PRP) and phosphate buffer saline in semen prepared by swim – up technique. This research included 119 semen sample evaluated according to sperms parameters stated in WHO and divided into 2 groups. The first group treated with equal quantity of phosphate buffer saline (250) μm contain 10% human serum albumin (HSA) while second group treated with equal quantity of phosphate buffer saline (250) μm contain 10% human serum albumin (HSA) and 2% platelet rich plasma. The samples are prepared by swim – up method. Applying swim up technique using-PBS+PRP (HAS) medium resulted in highest sperm parameters in a highly significant manner (p < 0.001). The values were far better in Swim -up PBS (HAS) with added 2% PRP than those produced by swim up –PBS (HAS) alone. The statistical analysis shows that the variations between Swim up-PBS (HAS) with addition 2% PRP media and swim -up PBS (HAS) were highly significant.
