B. see if the sperm are viable in the cervical mucus
C. test for longevity of sperm in the female reproductive tract
D. determine the proportion of living sperm



Answer :

Final answer:

The viability test assesses the proportion of living sperm to determine their ability to potentially fertilize an egg.


Explanation:

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.
