2. Figure 1
Schematic cross-section of the sperm selector indicating the ejaculate in the outer ring (dots) and medium in the centre well (wave lines). Cover glass is not shown. (a) Sperm selector consists of the actual chamber (glass or polyethylene) and a U-ring (top left). (b) After filling of the chamber, the U-ring is inserted and creates a capillary bridge allowing motile spermatozoa to swim to the centre well (theoretical path of migration indicated by arrow).
