A new way to assess male fertility
(PHYSorg.com Chemistry)

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 reporting in Analytical Chemistry 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.
