Abstract :The aims of this study were to determine the relation of glucose transporter 3 insert ignore into journalissuearticles values(GLUT3); expression on the spermatozoa membrane with the quality of semen in Asian elephants. Fresh semen samples were collected from 10 Asian elephants and classified according to the percentage of motile sperm into Group 1 insert ignore into journalissuearticles values(≤ 20%; n = 4 males);, Group 2 insert ignore into journalissuearticles values(>20% to 60%; n = 3 males);, and Group 3 insert ignore into journalissuearticles values(>60%; n = 3 males);. The immunocytochemistry results showed the presence of GLUT3 at the principal and end piece of the sperm tail. GLUT3 expressions in each group were significantly different insert ignore into journalissuearticles values(P < 0.05);. The group with good sperm motility insert ignore into journalissuearticles values(Group 3); significantly insert ignore into journalissuearticles values(P < 0.05, R = 0.960); expressed higher GLUT3 insert ignore into journalissuearticles values(99.40 ± 0.69%); than Group 1 insert ignore into journalissuearticles values(21.46 ± 10.25%); and Group 2 insert ignore into journalissuearticles values(84.37 ± 8.70%);. Moreover, the percentage of live sperm of this group was also significantly highest insert ignore into journalissuearticles values(P < 0.001, R = 0.938); at 82.00 ± 4.00% compared to Group 1 insert ignore into journalissuearticles values(20.75 ± 3.30%); and Group 2 insert ignore into journalissuearticles values(53.00 ± 8.02%);. Therefore, the motility of Asian elephant spermatozoa and percentage of live sperm may be influenced by GLUT3 expression, and GLUT3 expression may be involved in energy production via the glycolytic pathway.
