Center of Assisted Reproduction in University Hospital Brno is the oldest one in Czech Republic and is linked to academic institution, Masaryk University Brno. We have long time experiences with the therapy of human infertility. During last years we are focused on evaluation of novel techniques in assisted reproduction.Sperm selection for assisted reproductive techniques (ART) is very important step for successful in vitro fertilization [1-6].Classical ICSI (introcytoplasmatic sperm injection) method is not optimal for subjective sperm selection based on only morphology and motility of spermatozoa. For this reason there is currently a trend to combine multiple methods to segregate inappropriate sperm based on multiple parameters to increase the likelihood of successful fertilization. Is it usually classical separation method like swim-up or density gradient and a group of additional techniques like PICSI (ICSI with preselected sperm). One of these additional methods is MACS (magnet activated cell sorting). How many methods are best combined, and whether a new MACS selection method really brings a better prognosis in terms of conception success, or from the point of view of the subsequent development of the foetus, has already been studied several times.
