To evaluate and compare the efficacy of various extenders for the cryopreservation of epididymal cat spermatozoa, two experiments were planned. Bovine and equine commercial extenders in the experiment 1 and TRIS–egg yolk–based extenders in experiment 2 were separately studied since the number of sperm collected per cat is reduced. Epididymal sperm samples were packaged into 0.25-ml straws and frozen. Vigour, motility, morphology, acrosome status, sperm viability and functional membrane integrity were assessed at collection, after cooling and after thawing, while DNA integrity was evaluated at 0- and 6-h post-thaw. Experiment 1 compared the effect of three non-feline commercial extenders – based on TRIS–egg yolk (Triladyl), egg-yolk-free medium (AndroMed) and skimmed milk-egg yolk (Gent) – on the quality of frozen-thawed epididymal cat sperm. Values for sperm motility and functional membrane integrity in cooled sperm diluted in Triladyl were higher (p < 0.001) than those recorded for Andromed and Gent. Except sperm morphology, the other assessed characteristics showed significant higher values in frozen-thawed sperm diluted in Triladyl than in Andromed and Gent extenders. Experiment 2 analysed the effects of three TRIS–egg yolk–based extenders, one non-feline commercial (Triladyl) and the other two prepared using different monosaccharides (glucose and fructose), on freezing-thawed sperm. Results showed that specifically prepared extenders for cryopreservation of feline spermatozoa performed better than the commercial extender Triladyl, although sperm quality during the freezing-thawing process did not significantly differ associated with the type of monosaccharide (glucose vs fructose) added to the mentioned extenders. Although TRIS–egg yolk–based extenders prepared in experiment 2 improved sperm cryoprotection, Triladyl remains a good option for practitioners who, for ease of use and availability, prefer to work with commercial extenders.
