Plasma testosterone was measured through a stimulation test using the gonadotrophin-releasing hormone agonist, buserelin. Following intra-muscular administration of buserelin, there was an increase (P &amp;lt; 0.05) in testosterone concentration in the peripheral circulation 4 h later. Quantitative testicular histology of this species was described for the first time. Eight stages of the seminiferous epithelium cycle were identified in 10 possums and their relative frequency determined. Spermatozoa were recovered from the cauda epididymides of hemi-castrated possums and cryopreservation conducted in straws (6\u00b0C min\u20131) using final glycerol concentrations ranging between 2 and 20% in Tris-citrate egg yolk extender (v\/v). Frozen straws were thawed and post-thaw motility, rate of motility, the percentage of live\u2013dead spermatozoa and the percentage of sperm with swollen decondensed nuclei recorded. Similar to other marsupial sperm, common ringtail possum cauda epididymidal spermatozoa required high levels of glycerol (10\u201316%) in order to maintain post-thaw viability.<\/jats:p>","DOI":"10.1071\/rd07206","type":"journal-article","created":{"date-parts":[[2008,3,10]],"date-time":"2008-03-10T23:49:51Z","timestamp":1205192991000},"page":"391-401","source":"Crossref","is-referenced-by-count":17,"title":["Testosterone secretion, testicular histology and the cryopreservation of cauda epididymidal spermatozoa in the common ringtail possum (Pseudocheirus peregrinus)"],"prefix":"10.1071","volume":"20","author":[{"given":"D.
