How we determine the sperm quality
- All Cryos’ staff is trained in the procedures through our own carefully developed training courses build on more than 30 years of experience. This ensures the same high standards in all our laboratories.
- When we receive a sample, we freeze the entire ejaculate in straws. All straws are stored in liquid nitrogen which ensures a stabile temperature of -196 degrees until use. To determine the quality, one straw from each ejaculate will be thawed and analysed. The result of this analysis determines the MOT of the ejaculate.
- We determine the sperm quality according to WHO’s standard 4th edition. In all our laboratories, we use CASA (Computer Assisted Sperm Analyzer) to count the sperm cells via microscopy. We count 500 cells or 5 frames (whichever is achieved first) before determining the result of the analysis. CASA ensures a more consistent count than what is possible through a manual process.
