Anmärkningar

  • Sperm selection techniques, such as magnetic activated cell sorting (MACS) and colloid centrifugation, are reported to select good quality spermatozoa from semen samples of various species. Although the sperm quality of fresh boar semen is usually good, cryopreservation has a negative effect on parameters such as plasma membrane integrity and mitochondrial activity. Therefore, the objective of the present study was to determine whether MACS or centrifugation through a single layer of colloid (Single Layer Centrifugation, SLC) would be beneficial in enriching thawed boar sperm samples for viable spermatozoa with active mitochondria and good chromatin integrity. Frozen samples from three boars, three ejaculates per boar, were thawed and split. One part was selected by MACS, one was prepared by SLC, and the remainder served as the control. Controls and the selected sperm samples were evaluated for sperm quality (plasma membrane integrity, chromatin integrity, mitochondrial membrane potential and production of reactive oxygen species). Although several aspects of sperm quality were improved in the SLC-selected sperm samples compared to control, the flow-through MACS samples were only improved in having a lower proportion of spermatozoa with immature chromatin (Hi green fluorescence) compared to the labeled control. Sperm quality in the SLC samples was better than in the flow-through samples from MACS. Therefore, despite promising reports of the use of MACS for selecting good quality spermatozoa from semen in other species, the method was not useful for improving sperm quality in the thawed boar sperm samples in this experiment.
