UK fertility clinics use a range of sperm analysis equipment, from manual microscopy setups to advanced Computer-Assisted Sperm Analysis (CASA) systems. CASA platforms use high-speed cameras and motion-tracking software to assess sperm concentration, progressive and non-progressive motility, morphology, and a full kinematic profile including VCL, VSL, and VAP. These systems offer superior reproducibility compared to manual assessment and are increasingly the standard of care in accredited UK andrology labs. Cryolab supplies specialist sperm analysis equipment to UK clinics and andrology units.
