ABSTRACT
<p><b>OBJECTIVE</b>To study the oxidation damage of active oxygen (ROS) to human sperm acrosome and ultrastructure, and study the function mechanism about Cuscuta japonica treating male's infertility and asthenoospermia.</p><p><b>METHOD</b>By using the Percoll gradient centrifugation, the sperm with normal physiological function were selected for the normal sperm model, and the sperm suspension were divided into the normal group, the model group, the positive control group (Vitamin C group), and the lugh, the median and the low dose gvoups of C. japonica. The ROS made from hypoxanthine-xanzine xanzine(HX-XO) and different content (0.125, 0.25, 0.5 g x mL(-1)) of extract were incubated with sperm in the oxygen environment. The acrosomic integrity rate were calculated and the sperm acrosome and ultrastructure were observed.</p><p><b>RESULT</b>The content (0.125, 0.5 g x mL(-1)) of extract had no obvious difference as compared with Vitamin C (0.25 mg x mL(-1)) in protecting the acrosome and ultrastructure, but the content (0.25 mg x mL(-1)) of extract was significantly better than Vit C (P < 0.001).</p><p><b>CONCLUSION</b>The suitable content of extract from C. japonica can significantly protect the sperm membrane, the acosomic structure and the mitochondrion function from the damage caused by ROS.</p>
