When working with insemination or fertility assessment in stallions, it is crucial to quickly determine what proportion of the sperm cells are actually alive. Motility does not tell the whole story – even immotile sperm can be alive. This is where Sperm VitalStain comes in as one of the most reliable tools in the laboratory.
