AB - Abstract Sperm washing techniques, based on the swim-up principle used before inseminating the human oocyte in in-vitro fertilization and embryo transfer programmes (IVF–ET), usually require prior centrifugation which causes damage to the sperm cell. A technique is described for separating sperm at laboratory temperature based on sperm migration–sedimentation principles, using two concentric tubes and recovering 70–90% forward-moving cells. A group of 17 patients is presented who were managed with this method. The results were 85% fertilization rate, 4% polyspermia and six clinical pregnancies spermatozoa, migration-sedimentation, swim-up This content is only available as a PDF. © IRL Press at Oxford University Press
