Summary

CAT SPERMATOZOA WERE SUBJECTED TO REPEATED RAPID COOLING TO 273 K (0 DEG C) EITHER UNDILUTED OR EXTENDED IN AN EGG YOLK DILUENT. A SIGNIFICANT DECLINE IN MOTILITY OCCURRED WITH EACH SUCCESSIVE COOLING CYCLE, BUT EGG YOLK REDUCED THE MAGNITUDE OF THE EFFECT. SLOW COOLING OVERPERIODS FROM 11 TO 300 MIN REDUCED MOTILITY AND INCREASED THE PERCENTAGE OF CELLS STAINING WITH EOSIN. DIFFERENCES BETWEEN COOLING RATES WERE NOT SIGNIFICANT.
