A method of cryopreserving sperm cells which may include cooling the quantity of sperm cells to a holding temperature, maintaining the sperm cells substantially at the holding temperature for a period, and supercooling the sperm cells by cooling the sperm cells at a first cooling rate to a temperature that approaches a critical temperature zone at which ice crystal formation and changes in osmotic pressure damage sperm cells and then cooling the sperm at a second cooling rate faster than said first cooling rate through said critical temperature zone.

Methods for processing sperm cells

A method of processing animal sperm cells that includes: collecting sperm cells from a male animal; sorting the sperm cells to obtain a quantity of sperm cells having a desired characteristic, the quantity of sorted sperm cells being contained in a first volume of fluid having a first concentration of sperm cells; and subjecting the sperm cells to concentration steps in which the concentration of the sperm cells is increased to a second concentration greater than the first concentration.
