Motility Classifications

• Motility ranges are classified as progressively motile, non-progressively motile, or non-motile. Non-progressively motile and non-motile are considered poor for fertility.
  
  

Total Motility

• Total motility is a term expressed as a percentage of sperm with any movement whatsoever. According to ColoState.edu, less than 50 percent total motility is unusual and low in humans.
  
  

Considerations

• Men who have long periods of sexual inactivity tend to temporarily experience poor sperm motility.
  
  

Testing Factors

• Examiners must protect sperm samples from the heat or cold. This could adversely affect sperm motility causing a false test.
  
  

Implications

• Poor sperm motility indicates male fertility concerns. Without adequate directional movement, there is a lower chance of sperm finding an egg naturally.
