Possibilities of using the European bison (Bison bonasus) epididymal spermatozoa collected post-mortem for cryopreservation and artificial insemination: a pilot study

摘要

BackgroundEuropean bison is the largest mammal in Europe with the population of approximately 4000 individuals. However, there is no report of post-mortem spermatozoa collection and cryopreservation from this species and the aim of this study was to test if the epididymal spermatozoa collected post-mortem from European bison are suitable for cryopreservation and artificial insemination (AI).
