某医院2730例男性精液质量分析

Analysis on the quality of male semen: 2730 cases

目的分析某医院不孕不育专科就诊男性的精液质量水平,对比不同年龄段男性精液质量的差异。方法收集来某医院就诊男性精液分析数据2 730份,对精液主要参数进行统计分析,再以年龄分为3组(A组年龄<30岁,B组30～39岁,C组年龄≥40岁),对比各年龄组间精液参数存在的差异。结果精液异常1 584例,异常率为58.02%。异常参数主要以精子形态异常为主,占40.59%。各组精液参数中,大部分精液参数均值随着年龄的增加呈下降趋势,异常发生率随着年龄的增加呈上升趋势,C组的精子总活力、前向活动精子百分率和正常形态精子百分率与A、B组差异有统计学意义(P<0.01)。结论某医院就诊男性精液异常率较高,主要以精子形态异常为主;男性40岁以后精液质量明显下降。

Objective To analyze the quality of the semen of patients receiving treatment in the infertility division of a hospital, and compare the differences in semen quality among different age groups. Methods The data of the semen of 2730 males receiving treatment in a hospital were collected, statistical analysis was conducted on the main parameters of semen. The cases were divided into three age groups (Group A with the age of less than 30 years, Group B with the age of 30-39 years and Group C with the age of no less than 40 years), and the differences in semen parameters were compared among different age groups. Results There were 1584 cases with dysspermatism, accounting for 58.2%. The abnormal parameters are mainly abnormal sperm morphology, accounting for 40.59 %. Among the semen parameters of each group, the mean value of most semen parameters decreased with the increase of age, the incidence of dysspermatism increased with the increase of age, and there was statistical difference in the total sperm motility, percentage of forward motile sperm and percentage of normal morphological sperm in Group C and Group A and B (P<0.01). Conclusion Thee rate of dysspermatism in the hospital is very high, mainly manifesting as abnormal sperm morphology. The semen quality of males over 40 years old decreases significantly.
