Sperm vitality is reflected in the proportion of spermatozoa that are “alive”. Sperm vitality should be determined in semen samples with 50% or more immotile spermatozoa. 

The technique is based on the principle that dead cells will take up the eosin, and as a result stain red. The nigrosin provides a dark background, which will make it easier to asses the slides.

VitalScreen provides an accuracy check of the motility evaluation since the percentage dead spermatozoa should not exceed the percentage immotile spermatozoa.
