摘　　要：目的了解冷冻对人精子顶体酶活性影响。方法分光光度比色法测定精子顶体酶活性。结果冷冻后精子顶体酶活性明显低于冷冻前(P<005)。结论冷冻后人精子顶体酶活性减少。Objective To study the effect of freezing on sperm acrosin activity. Methods The sperm acrosin activities were determined by spectrophotometer. Results The sperm acrosin activities were significantly decreased after freezing(P<0.05). Conclusion The freezing could affect the sperm acrosin activities.
