ABSTRACT

Currently, more than 16,000 plant and animal species are imminently threatened by extinction, often as a direct consequence of anthropogenic influences. One of the measures to halt that process is genetic resource banking. This short review focuses on mammal sperm cryopreservation in combination with assisted reproduction techniques. It summarizes general problems, recent developments, and currently applied protocols and gives an overview of hitherto existing successes of assisted reproduction measures in wild animals in the light of conservation efforts.
