Popis: Cyclodextrins improve post-thaw viability and motility of semen as well as mediate cholesterol efflux and subsequent acrosome reaction in spermatozoa from several species. The objectives of this study were: (a) to assess the effect of prefreeze addition of 60 mM hydroxypropyl-β-cyclodextrin (β-CD) on post-thaw viability and motility of jack and stallion semen cryopreserved in ethylene glycol-based freezing extenders containing 5% or 20% (v/v) egg yolk (LEY and HEY, respectively), and (b) to evaluate the ability of 1 μM calcium ionophore A23187 and/or 60 mM β-CD to induce acrosome reaction in thawed jack and stallion spermatozoa. Post-thaw motility of spermatozoa cryopreserved in HEY was higher (P
