Claim 0:
1. A method for sorting sperm, comprising:
delivering a sample of sperm to an inlet of a fluidic system;
allowing some sperm from the sample of sperm to traverse a flow path in a flow-free manner through the fluidic system toward an outlet of a filter chamber of the fluidic system;
filtering the sperm within the filter chamber using a filter and gravity to restrict movement of the sperm through the filter, wherein the filter has micropores sized to permit a head of the sperm in the sample to pass therethrough;
allowing the sperm after passing through the filter and overcoming gravity, to pass in a flow-free manner through the outlet and into an additional collection channel and/or chamber arranged at the outlet such that it is in fluid communication with the filter chamber and such that a percentage of motile sperm that are present at the additional collection channel and/or chamber is greater than a percentage in the sample; and
harvesting sperm in a liquid from the additional collection channel and/or chamber to retrieve the harvested sperm from the fluidic system, wherein the harvested sperm comprise some live, functional sperm from the sample.
