RESUMO
@#ObjectiveTo observe the protective effect of extract from Morindae officinalis on the oxidative injury of human sperm motility.MethodsThe sperm specimens were cultivated in vitro, the reactive oxygen species (ROS) was made from hypoxanthine-xanzine xanzine (HX-XO), and sperm specimens were co-incubated with ROS and different dosages of extract and oxygen. The motor parameters were evaluated, the motility were analyzed by the test of capillary tube penetrating, and compared with the control group.ResultsThe sperm function were injured, the motility and penetrating ability decreased evidently under the action of ROS, and with a significant difference compared with the normal group ( P<0.001). The sperm motility and penetrating ability could be improved by all of the small, medium and massive extract compared with vitamin C, especially 0.25 and 0.5 g/ml Morindae officinalis had more evident action in the rate of progressive motility and vitality exponent.ConclusionThe ROS can injury the sperm motility and penetrating ability, the appropriate content of extract from Morindae officinalis can significantly intervene peroxidation in sperm by the ROS, and protect the sperm motility.
