目的:了解目前男性精液质量情况以及年龄对精液质量的影响。方法:选取男科门诊就诊患者中行精液检查的270例患者,分为5组:20～25岁组、26～30岁组、31～35岁组、36～40岁组以及40岁以上组,采用计算机辅助精液分析(CASA)技术以及Shorr染色法进行精液的动态和形态分析。结果:随着年龄的增长,精子活力呈逐渐下降趋势,但各精液参数在各组间比较并无明显统计学差异;31～35岁组各项精液参数指标均达到WHO标准的比率最高,占该组人数的61.76%,比率最低的是40岁以上组,占该组人数的50.0%。结论:随着年龄的增长,男性的精液质量呈下降趋势,但是多数男性仍然具有较好的生育能力。
Objective: To understand the current male semen quality and age of semen quality. Methods: A total of 270 patients were enrolled in this study. They were divided into five groups: 20 to 25 years old, 26 to 30 years old, 31 to 35 years old, 36 to 40 years old, and 40 years old or older. Computer-aided semen analysis (CASA) technique and Shorr staining were used for dynamic and morphological analysis of semen. Results: The sperm motility decreased gradually with the increase of age, but no significant difference was found in the semen parameters between the groups. The semen parameters reached the WHO standard in the age group of 31-35 years, accounting for The group of 61.76% of the population, the lowest rate is more than 40 years old group, accounting for 50.0% of the group. CONCLUSIONS: Men’s semen quality declines with age, but most men still have good fertility.
