The viability test assesses the proportion of living sperm to determine their ability to potentially fertilize an egg.
Viability test is used to determine the proportion of living sperm. It assesses the sperm's ability to survive and potentially fertilize an egg. One method, the swim-up technique, helps gauge the quality of sperm by allowing the healthiest sperm to swim up to a culture medium, leaving behind debris and aiding in selecting optimal sperm for fertilization procedures such as in vitro fertilization.
