We’re thrilled to share that our latest research, “Retrospective study investigating the performance of the SQA-Vision analyzer compared with manual semen analysis,” has been published in Scandinavian Journal of Clinical and Laboratory Investigation! 📄✨
This study, spanning four years and including over 1,100 cases, demonstrates the robust performance of the SQA-Vision system in routine sperm analysis. The findings showed strong correlations with traditional manual methods, achieving impressive Sensitivity, Specificity and Correlation across key sperm parameters, including:
- Sperm Concentration: Sensitivity 0.90 | Specificity 0.99
- Progressive Motility: Sensitivity 0.98 | Specificity 0.99
- Sperm Motility: Sensitivity 0.87 | Specificity 0.99
- Normal Morphology: Sensitivity 0.88 | Specificity 0.99
- Round Cells: Sensitivity 0.98 | Specificity 0.99
- Strong Correlation: The SQA-Vision analyzer showed high correlation coefficients with manual methods, ranging from 0.81 to 0.98 across various sperm parameters, highlighting its accuracy and reliability in routine analysis.
The study reinforces our commitment to providing cutting-edge solutions that streamline laboratory processes without compromising accuracy. 💡🔬
A huge thank you to our dedicated team and collaborators for their hard work in making this publication possible. This is an exciting step forward for automated semen analysis, and we’re excited to continue leading innovation in this field.

Abstract:
The objective of this study was to compare the results of semen analysis using the manual method and the SQA-Vision sperm analyzer after four years of practice and with a large cohort of patients. This was a comparative study of 1130 cases collected for semen analysis between October 2019 and October 2023, which were analyzed simultaneously and independently by different operators using the manual microscopic method and an SQA-V automated analyzer. For each sample, sperm concentration, progressive motility, motility, normal morphology, and round cells count were performed. There was no significant difference between the SQA-V method and manual assessment for all sperm parameters (Mann–Whitney test p > 0.05). according to the parameter studied, there was a strong correlation (rho = 0.81) and a very high correlation (rho = 0.98) between manual assessment and the SQA-V method. in the analysis of sperm concentration, the sensitivity and specificity were 0.90 and 0.99, respectively. The sensitivity and specificity for the analysis of sperm progressive motility were 0.98 and 0.99, respectively, while the sensitivity and specificity for the analysis of sperm motility were 0.87 and 0.99, respectively. The sensitivity and specificity for the analysis of normal morphology were 0.88 and 0.99, respectively. Regarding the analysis of round cells, the sensitivity and specificity were 0.98 and 0.99, respectively. The results of this retrospective study indicate that the SQA-V system offers satisfactory performance for routine sperm analysis.
