Vitaltest allows the evaluation of the quality of the sperm membrane and the differentiation between live spermatozoa (intact membranes) and dead ones (affected membranes).
- Rapid application, reliable, and low-cost technologies are essential for quantifying the state of the cell populations. The viability of spermatozoa in any ejaculate is related to the presence or absence of altered membranes.
- Its use is advisable for patients with progressive motility below 40% to evaluate the proportion of live and dead spermatozoa. This test is used as a check on the motility evaluation, as the percentage of dead cells should not exceed that of immotile spermatozoa.
- Cases of necrozoospermia are related to epididymal pathology (Wilton et al, 1988; Correa-Pérez et al, 2004). A high percentage of vital but immotile spermatozoa is indicative of structural defects in the flagellum (Chemes and Rawe, 2003).Applications of Vitaltest®
- Immediate determination of the quality of the membrane of spermatozoa in the ejaculate.
- Determination of necrozoospermia.
- The incubation of sperm with the reagent is not necessary.
