Regulated & Certified Company | Following UK NEQAS Quality Control
The system requires minimal training, and <1 minute handling time per analysis. The system seamlessly integrates with clinic software and fully supports ExSeed home tests as well.
The digital microscope allows capturing multiple fields of view with magnification capabilities up to 200x. Assess concentration, motility, morphology, round cells, and aggregations.
Customize the sperm and morphology assessments to align with the specific preferences and requirements of your clinic.

The CASA Lite system offers advanced semen analysis in a compact, easy-to-use format — delivering fast, lab-quality results across critical fertility parameters:
Sample Volume (Manual input): Ensures adequate semen volume for reliable assessment.
Sperm Concentration: Measures the number of sperm per milliliter.
Total Sperm Count: Calculates the total number of sperm in the sample.
For even deeper insights, CASA Lite measures individual sperm movement characteristics:
VCL (Curvilinear Velocity)
VSL (Straight-Line Velocity)
VAP (Average Path Velocity)
ALH (Lateral Head Movement)
BCF (Tail Beat Frequency)
Linearity, Wobble, Straightness, and Angular Displacement
Motile Sperm Count: Identifies the number and concentration of moving sperm.
Total Motility: Percentage of sperm that show movement.
Progressive Motility: Focuses on sperm moving efficiently forward — crucial for fertilization.
Rapid and Slow Progressive Movement: Differentiates between fast and slower moving sperm.
Non-Progressive and Immotile Sperm: Detects sperm with limited or no movement.
Normal Forms: Percentage of sperm with healthy, normal structure.
Round Cell Concentration: Monitors other cell types that may indicate infection.
Aggregation: Detects sperm clumping, which can impact fertility.

At ExSeed Health, we understand the critical importance of reliable sperm analysis for successful fertility assessments. CASA Lite has undergone rigorous testing with samples from the UK’s National External Quality Assurance Scheme (NEQAS) for sperm analysis.
CASA Lite analysis demonstrates an impressive correlation with NEQAS data. This comparison signifies CASA Lite’s exceptional performance in sperm analysis, providing you with the confidence you need to rely on its results for accurate and consistent decision-making.
In addition to external NEQAS validation, CASA Lite has been independently compared to manual semen analysis in a UK fertility clinic setting. The system demonstrated strong agreement for sperm concentration (R² = 0.91) and progressive motility (R² = 0.92), with 97% overall diagnostic accuracy when assessed against WHO 6th edition reference thresholds.

The recording stage takes around 10 seconds. After this, you can run any number of tests in parallel whilst the former tests are being analyzed in the cloud. The full cloud analysis typically takes 2-3 minutes, depending on the internet speed.
Our system has import/export APIs available and can integrate into most systems on the market that allow for third-party integrations.
The device is easy to clean using lint-free wipes and 70% ethanol or isopropanol. Do not use acetone to clean the device, and be aware that the device can’t be autoclaved.
You don’t need to manually assess the samples going through the system as it is fully automated. However, as our system is also completely transparent, you are able to see all the videos and the tracks, which allows for easy internal validation.
To ensure the accuracy and quality control of the system, the slides used must be provided by ExSeed.
No – intuitive software and onboarding included.
None, all updates and validation included.
