Interpretive Summary: Captive assurance colonies play an integral part in the conservation and management of threatened and endangered amphibian species. Maintaining a high level of genetic diversity in captive colonies is imperative for the recovery of wild populations that are experiencing drastic declines in numbers of animals. Cryopreservation and biobanking of male gametes to link in situ and ex situ groups of threatened and endangered species have been recommended conservation strategies for decades, yet only recently has the series of reproductive techniques been implemented in a coordinated fashion to create offspring for reintroducing into the wild.

Technical Abstract: Here, we show how reproductive technologies, such as hormonal therapy,IVF, and cryopreservation of sperm can be used to link in situ and ex situ populations of endangered species of amphibians, especially where at-risk captive populations exist and long-term sustainability is a challenge without the influx of new genetic variation from wild sources.
