Magnetic-activated cell sorting (MACS) using paramagnetic annexin V-conjugated
microbeads eliminates spermatozoa with externalized phosphatidylserine, which is
considered one of the features of apoptosis. The objective of this study was to evaluate
sperm recovery following the use of MACS as a sperm preparation technique. Mature
spermatozoa were separated and divided into two fractions: the first was prepared by
density gradient centrifugation (DGC) and MACS, while the second was prepared by DGC …
