目的:探讨精子正常形态百分率与精液参数的关系。方法:对370份精液标本进行精子形态学分析和精液常规检测,按精子正常形态百分率分为≥15%组(1组)、10%～14%组(2组)、5%～9%组(3组)、≤4%组(4组),分析比较各组精液参数的相关性。结果:各组间精液量相比差异均无统计学意义;4组间精液密度相比差异均有统计学意义(P<0.05);1组与2、3、4组的活力(a级、a+b级)比较差异有统计学意义(P<0.05);2、3、和4组各组间两两比较活力均无差异。结论:随着正常形态精子百分率的减少,精液密度随之减少,有密切相关性;而精子活力在正常形态精子百分率<15%的3组间比较无差异,说明随着正常形态精子百分率的减少,精子活力不随之减少。
Objective: To explore the relationship between the percentage of sperm normal morphology and semen parameters. Methods: 370 sperm samples were analyzed for sperm morphology and sperm routine test. According to the percentage of normal sperm morphology, the sperm morphology was divided into 15% group (group 1), 10% ~ 14% group (group 2), 5% -9% (3 groups), ≤4% group (4 groups). The correlation between semen parameters in each group was analyzed and compared. Results: There was no significant difference in semen volume between groups (P <0.05). There were significant differences in semen densities between the four groups (P <0.05) a + b) (P <0.05). There was no difference in the vigor of every two groups between groups 2, 3 and 4. Conclusion: With the decrease of the percentage of normal spermatozoa, there is a close correlation between sperm density and sperm motility. Among the three groups with normal sperm percentage <15%, there is no difference, indicating that as the percentage of normal sperm decreases , Sperm motility does not decrease.
