RESUMEN
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+/-.2 ml. Mean value of sperm concentration, motility, forward progression using CS system were 83.4+/-5.7x106/ml, 52.3+/-6.4% and 48.6+/-3.4%, respectively. And mean value of sperm concentration, motility, forward progression using SQA system were 78.2+/-2.9x106/ml, 57.0+/-4.0% and 50.6+/-1.9%, 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.
