Abstract: Upon the results of this study, mean motility of spermatozoa before and after dilution in different extenders and also sperm concentration were very significantly differ (p< 0.01). Mean percentage of motile sperm of 7 old buffaloes pre-freeze and post-thaw in Cornell and TRIS extenders comparing with IVT and Minnesota extenders in 2 years old buffaloes have very significant difference(p< 0.01). The mean percentage of abnormal and dead spermatozoa with IVT and Minnesota extenders in 2 years old buffaloes comparing with Cornell and TRIS extenders in 7 old buffaloes have very significant difference(p< 0.01). Interactions between ages of buffaloes and extenders type in different parameters were very significant (p< 0.01). But interactions between extenders type and weeks of experiment and also between ages of buffaloes and weeks of experiment and triple interactions were not significant (p>0.05).
