p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt">The cryopreservation of spermatozoa constitutes a valuable tool for the captive breeding management of valuable and/or threatened species. Chinchilla lanigera is a species almost extinct in the wild, and the domestic counterpart has one of the most valuable pelts in the world. The objectives of this study were to: (i) compare the functional activity of post-thawed chinchilla spermatozoa cryopreserved at )196C either with glycerol (G) or ethylene glycol (EG) as cryoprotectants (1 M final concentration) and (ii) investigate the effects of incubating the gametes for 4 h in the presence or in the absence of the cryoprotectants; evaluations were p
