DefinitionThis section has been translated automatically.
Test for testing spermatozoa membrane function against hypoosmolar loads as an indirect parameter for sperm vitality and fertilization ability. Great importance in the investigation of male fertility, especially since the results of the HOS-Test correlate highly significant with the results of the HOP-Test.
ImplementationThis section has been translated automatically.
Native spermatozoa are incubated with a hypoosmolar solution of sodium citrate and fructose at 37 °C for 30 minutes; the proportion of swollen spermatozoa in the microscopic preparation is then counted (standard value > 60% swollen spermatozoa).
