VIABILITY AND PLASMA MEMBRANE INTEGRITY OF THE SPOTTED BUFFALO EPIDIDYMAL SPERMATOZOA AFTER THAWING WITH THE ADDITION OF DEXTROSE INTO THE EXTENDERKeywords: epididymal sperm , cryopreservation , dextrose , spotted buffalo Abstract: h e objective of this study was to obtain the viability and plasma membrane integrity of the spotted buff alo epididymal sperm after addition of dextrose into Andromed extender. Spermatozoa that have been collected from cauda epididymis were diluted with Andromed extender as control (K) and Andromed + 0.2% dextrose (P1) and Andromed + 0.4% dextrose (P2) as treatments. h e results showed that the quality of epididymal spermatozoa decreased during cryopreservation process. h e percentage of motility after thawing in P1 (46%) and P2 (46.67%) were signifi cantly higher (P<0.05) compared to K (41%) as well as the percentage of live sperm in P1 (58.8%) and P2 (60%) compared to K (52.2%). h e percentage of membrane integrity in P1, P2 and K were 67.4; 66.8 and 68 %, respectively. In conclusion, the addition of 0.2 and 0.4% of dextrose into Andromed acted as an extra cellular cryoprotectant and could maintain the viability and membrane integrity of the spotted buff alo epididymal spermatozoa after thawing.
