Computer Aided Sperm Analysis


medeaLAB CASA is a well established system for standardized sperm analysis which has been installed in more than 15 countries worldwide. Semi-automatic sperm analysis is performed according to WHO standards, focusing on routine requirements in human reproductive medicine. The basic module “medeaLAB Concentration & Motility” is complemented by the medeaLAB Morphology Analyzer.




  • Generation of a complete spermiogram within a few seconds
  • Video recording and storage for re-analysis of sperm samples
  • Works on positive phase contrast, no special objective required
  • Accurate discrimination between sperm and non-sperm cells by multi-parametric filters (tail detector etc.)
  • High resolution mode for morphology analysis
  • Self-learning morphology analyzer, no adjustment of filters necessary
  • Analysis of external videos for inter-laboratory QC testing
  • MS Excel export of motility / concentration data for further analysis
  • Attractive price, reliable after-sales service
  • Hardcopy report layout in different languages (German, English, Greek, Chinese, etc.)

medeaLAB Concentration & Motility

Display / calculation of

  • Sperm concentration in mill/ml
  • Concentration of progressively motile sperm in mill/ml
  • WHO motility grades a, b, c, d in percent (old classification)
  • WHO motility progressive / local / immotile in percent (new classification)
  • VCL (curvilinear velocity) in µm/sec
  • VSL (straight-line velocity) in µm/sec
  • VAP (average path velocity) in µm/sec
  • WOB (wobble = VAP/VCL)
  • ALH (amplitude of lateral head displacement) in µm



medeaLAB Morphology Analyzer

Display / calculation of

  • Exact morphometry data for each individual sperm
  • Total number of analyzed sperm cells
  • % normal forms
  • % head abnormalities
  • % midpiece abnormalities
  • % tail abnormalities
  • % abnormalities of head and midpiece
  • % abnormalities of head and tail
  • % abnormalities of midpiece and tail
  • % abnormalities of head, midpiece and tail


The Morphology Analyzer is self-learning, no manual adjustment of morphology classes or filters necessary!
