The present study investigated effects of different doses of hyaluronan on sperm motility, vitality and morphology in human. Materials and Methods: Motility, vitality and morphology of raw semen was analyzed according to WHO criteria before and 4 hour after treatment with different doses of hyaluronan (0, 750, 1000 and 1250μg/ml). Results: The results of present study showed in the group treated with 1000 μg/ml hyaluronan compare to control group there was an increase in the percentage of stages 3 and 4 but a decrease in the number of stages 1 and 2. In the group treated with 1250 μg/ml stages 1 and 2 increased while stages 3 and 4 decreased. Vitality in all groups decreased except of the group treated with 1000 μg/ml hyaloronan.
