Sperm Motility

Sperm motility refers to the number of sperm that are moving. Sperm motility is measured during a semen analysis, which is typically performed on men undergoing fertility testing. Sperm need to be able to move forward in a straight line through the female reproductive tract to locate and then fertilize an egg.

An analysis of sperm motility can provide insight into how a man’s sperm moves, including their direction, speed, and endurance.

Asthenozoospermia or asthenospermia is the medical term for decreased sperm motility.
