## Abstract Summary: The viability and fertility of isolated mouse epididymal spermatozoa kept for up to 7 days at various temperatures (4ยฐC, 22ยฐC, and 37ยฐC) were determined. Spermatozoa kept for 3 days at 22ยฐC were still active, while those kept at 37ยฐC or 4ยฐC exhibited great reduction in motility
recognized the necessity of controlled slow cooling for the low temperature preservation of bull semen. They suggested that cooling semen at rates between 1 " to 3ยฐC per minute over the range -I-5" to about -15ยฐC was optimal for recovery of viable and fertile bovine spermatozoa. Recently, more rapid
