摘　　要：目的　了解我国男性精液质量现状及其影响因素 ,探讨评价指标。方法　对在我国七省市妇幼保健所进行婚前体检的 5 62例正常男性志愿者进行精液质量测定和流行病问卷调查 ;资料分析方法采用一般描述性分析和主成分分析等。结果　男性精液量为 2 61± 1 10ml,精子密度为 64 47± 3 4 5 9± 10 6/ml,精子前向运动百分率 (X2 )为 5 9 89±17 11% ,精子存活率 (X3 )为 77 19± 11 87% ,精子正常形态率 (X4)为 78 2 3± 9 15 %。主成分分析第一主成分函数Z1=-8 5 12 5 4+0 0 0 13 6X1+0 0 3 192X2 +0 0 43 5 2X3 +0 0 3 984X4中 ,与其关系密切的是X3 、X2 和X4;第二主成分的大小主要取决于总精子数 (X1) ,函数式为Z2 =0 49192 +0 0 80 80X1-0 0 0 0 5 8X2 -0 0 0 5 10X3 -0 0 180 7X4。结论　精液质量各常规指标都符合WHO标准的对象只占 42 3 % ,精液质量有待提高。精子存活率、精子前向运动百分率及正常形态精子百分率高 ,第一主成分大 ,表明精子的质量较好 ,省市中以贵州对象最高 ,职业中以工人最高 ,户口以城镇最高 ;第二主成分主要指精子的数量 ,首次性冲动年龄越大、禁欲时间越长 ,数量越大 ;性生活次数越多 ,数量越小。Objective To understand the semen quality status and influential factors in China, to explore its evaluation index.Methods Experimental methods were used to measure the semen quality and questionnaire to understand the potential influential factors. There were 562 healthy male volunteers during their pre-marriage physical examinations among MCH centers in seven provincials and municipal regions; descriptive and principal component analyses were used to analyze data.Results semen volume (2.61±1.10ml), semen density (64.47±34.59×10 6/ml), sperm forward mobility (59.89±17.11%), sperm survival rate (77.19±11.87%), normal morphology (78.23±9.15%). The first principal component function is Z 1=-8.51254+0.00136X 1'+0.3192X 2'+0.04352X 3'+0.03984X 4',which is closely related to sperm survival rate (X 3), sperm forward mobility (X 2), normal morphology rate (X 4);The second principal component function is:Z 2=0.49192+ 0.08080X 1-0.00058X 2-0.00510X 3-0.01807X 4, which depends on the total amount of sperms (X 1).Conclusion Only 42.3% subjects meet all the common WHO standard of semen quality, indicating the semen quality should be improved. The multiple analysis of Z 1 showed that the highest Z 1 are among Guizhou's subjects, workers, or town residents. Multiple analysis of Z 2 showed that the elder age of the first sexual impulse, the longer abstinence, the more amount of semen; the more sexual activity, the less amount of semen.
