Current tests for male fertility include measuring the concentration and motility of spermatozoa. However, other characteristics of sperm, such as their ability to follow a chemical trail to the egg, can influence the likelihood of fertilization. Now, researchers have devised a quick and convenient microfluidic chip to assess this chemotactic response of spermatozoa, which could help provide a more complete picture of a man's fertility.
