ABSTRACT:
The potential fertility of a semen sample is evaluated using a kit comprising a collection tube with volume gradients on its side; a funnel which is fitted into the collection tube for guiding an ejaculate into the collection tube; a pipet containing a standard aqueous solution of the dye resazurin stored therein for metering a predetermined amount of the solution into the collection tube; an insulating sleeve for surrounding a glass containing hot water and the collection tube and for maintaining the water at an elevated temperature for a predetermined period of time, and a color chart ranging in color from the color of the semen sample and dye solution mixture immediately after mixing to the color of a corresponding mixture of the dye solution and a highly fertile semen sample, after being maintained at the same elevated temperature for the same period of time. Alternatively, for clinical laboratory use, the sample may be examined by a spectrophotometer, colorometer, fluorescent microscope or fluorometer in lieu comparing the mixture to a color chart.
