Objective: To evaluate the results of CASA systems and to compare its results. Methods: Fifty semen sampales were analysed. Concentration, motility and forward progression were evaluated simultaneously on the same semen samples using Cell Soft System-3000 (CS system) and Sperm Quality Analyzer-V (SQA system). Results: Mean semen volume was $2.8{pm}1.2;ml$. Mean value of sperm concentration, motility, forward progression using CS system were $83.4{pm}45.7{ imes}10^6/ml$, $52.3{pm}16.4%$ and $48.6{pm}13.4%$, respectively. And mean value of sperm concentration, motility, forward progression using SQA system were $78.2{pm}42.9{ imes}10^6/ml$, $57.0{pm}24.0%$ and $50.6{pm}21.9%$, respectively. There were no statistical significancy of sperm concentration, motility, forward progression between the two devices. Conclusion: SQA system variables well correlated with the CS system. As a screening test for semen quality, CS system and SQA system is considered as useful in the management of male infertility.
