WebApr 5, 2024 · Assessment of sperm vitality is an important component of semen analysis. It helps to distinguish spermatozoa that are alive and immotile from those that are dead. Sperm vitality can be assessed routinely on all semen samples by assessing the membrane integrity of the cell by identifying the spermatozoa with an intact cell membrane. WebThe advent of fluorescent staining improved microscopical evaluation of sperm, however, one of the major drawbacks remains, that is that one can only evaluate 100 or 200 sperm per sample. The advent of flow cytometry in the early 1970's and the development of new stains has led to more accurate means of assessing sperm viability.
