Sperm vitality, or viability, is the assessment of the proportion of live spermatozoa in a semen sample. It is particularly important when a large percentage of sperm are immotile (asthenozoospermia). This test distinguishes between 'necrozoospermia' (dead sperm) and sperm that are alive but lack motility due to structural defects (such as primary ciliary dyskinesia). Vitality is typically determined via dye exclusion (e.g., Eosin-Nigrosin) or the hypo-osmotic swelling (HOS) test.

Why Context Matters
Vitality results are highly sensitive to the duration of abstinence, the temperature at which the sample was kept, and the time elapsed between collection and laboratory analysis.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
