| Zusammenfassung: | A device (
12
) for separating motile sperm from a sperm-containing sample of semen comprises a tubular conduit (
14
) with a constrictor (
20
) therein. The constrictor is dimensioned to establish capillary flow of fluid therethrough. The sample is deposited in the larger cross-section upstream end (
16
) of the device, together with a fluid medium which entrains the semen through the constriction. The motile sperm, having passed through the constriction, swim against the flow and collect in a harvesting zone at the distal end of the conduit, from where they can be aspirated. Non-motile sperm are flushed from the device. |
