摘　　要：目的:了解禁欲时间对人精子顶体酶活性、精子密度和精子数的影响。方法:分光光度比色法测定精子顶体酶活性。结果:禁欲1～5d时,顶体酶活性是稳定的,而禁欲10d时顶体酶活性明显下降,与禁欲1d时顶体酶活性比较差异有显著性(P<0.05)。精子密度和精子数随禁欲时间增加而增加,禁欲10d精子密度约为禁欲1d精子密度2倍,禁欲10d精子总数约为禁欲1d的4倍。结论:禁欲时间影响顶体酶活性、精子密度和精子数。Objective： To study the effect of abstinence on human acrosin activity, sperm density, sperm number. Methods： The sperm acrosin activities were determined by spectrophotometer. Results： The sperm acrosin activities remained similar in 5 days of abstinence but decreased significantly after 10 days of abstinence. The sperm concentration increased gradually with the length of abstinence, being approximately t fold higher after 10 days of abstinence than that after 1day of abstinence.. The total sperm number after 10 days is about 4 times of that after 1 day. Conclusion： The length of abstinence affects acrosin activity, sperm density, and sperm number so that the abstinence period needs to be taken into consideration when performing these assays.
