Review

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.

Notes

Acknowledgments

We value Steffen Blottner as a colleague and friend with whom we successfully cooperated during many years and whose enthusiastic discussions we always enjoyed, and we hope that we can further profit from his vast experience and knowledge in reproduction biology. Steffen Blottner, who together with other colleagues from the IZW initiated and maintained the institute’s spermbank, focused his research both on the establishment of applicable cryopreservation protocols for endangered species and on the exploration of pathways involved in and factors regulating spermatogenesis.
