Sperm viability staining is a critical, simple test, but quality control is often ignored. Results are reported quantitatively as percent live sperm, making viability a CLIA high complexity test requiring 2 levels of quality control. Sperm viability staining is indicated when motility is low to determine whether the non-moving sperm have a motility defect or are dead.
Our Sperm Viability QC smears are human sperm stained with eosin Y and nigrosin counterstain. Live cells exclude the stain and appear white against the dark black-purple of the nigrosin. Dead sperm are stained pink. Analyze 200 cells from the high and low level slides and document results on the Levy-Jennings plots included with the product. Smears are coverslipped to improve their handling and longevity.
