This experiment documented the incidence and variability of sperm characteristics found in freshly collected and ex vivo-manipulated semen samples from a population of disease-free captive koalas with a special emphasis on the dynamic aspects of DNA

In this study, we have used single and double comet assays to differentiate between single- and double-stranded DNA damage in an effort to refine the interpretation of DNA damage in mature koala spermatozoa. We have also investigated the likelihood t

Alternative techniques for the cryopreservation of kangaroo spermatozoa that reduced or eliminated the need for glycerol were investigated including; (1) freezing spermatozoa with 20% glycerol in pre-packaged 0.25 mL Cassou straws to enable rapid dil

This study investigated whether cryopreservation-induced injury to koala spermatozoa could be explained using an experimental model that mimics the structural and physiological effects of osmotic flux. DNA labelling after in situ nick translation of

This study documented the extent of individual animal variation with respect to two proven methods of sperm cryopreservation in a captive population of 22 koalas. Semen samples were collected by electroejaculation, diluted in Tris-citrate glucose and

This study examined the effect of cryoprotectants (20% DMSO, a 10% DMSO/10% glycerol mixture, 20% glycerol and 1M sucrose solution) on kangaroo sperm structure and function, along with the effect of varying concentrations of glycerol on sperm mitocho

Swelling of koala sperm chromatin following cryopreservation has largely been attributed to the absence of intermolecular disulfide cross-linkages in the marsupial sperm nucleus. Fish spermatozoa also lack disulfide bonds within their chromatin, but

The aim of the present study was to determine whether analogues of gonadotrophin-releasing hormone (GnRH) could be used to both induce an acute testosterone response and suppress anterior pituitary function in male koalas, and induce a luteal phase i
