目的探讨提高计算机辅助精液分析(computer-assisted sperm analysis,CASA)复查结果稳定性的方法。方法对40位初次检查精液参数异常的患者,按照规范要求复查,精液分析根据WHO男科实验室手册第五版的质控方法执行精子浓度和体积的质量控制,然后将两次检查结果中精液体积、精子浓度、活力等参数进行t检验,并对浓度值进行相关性分析,分析两次检查结果的稳定性。结果两次检查结果精液参数比较差异无统计学意义,浓度值的相关系数为0.9518。结论在按照规范要求并严格执行精液分析质控后,是可以保证精液检查结果稳定性的。
Objective To explore a method to improve the stability of computer-assisted sperm analysis (CASA). Methods 40 patients with abnormal initial sperm parameters were reviewed in accordance with the requirements of the guidelines. The semen analysis was performed according to the quality control of sperm concentration and volume according to the quality control method of the Fifth Edition of the WHO Men’s Handbook of Laboratory Manuals. The volume of semen , Sperm concentration, vitality and other parameters t test, and the correlation analysis of the concentration values, analysis of the stability of the test results. Results There was no significant difference in semen parameters between the two examinations. The correlation coefficient of the concentration was 0.9518. Conclusions After the quality control of semen analysis is strictly followed in accordance with the regulations, it is possible to ensure the stability of semen examination results.
