Human reproductive technologies like sperm freezing and IVF could be used to save threatened species


More and more threatened species are relying on captive breeding to avoid extinction. Some species on the brink only exist in captivity, and others depend on captive breeding for their recovery before they’re released to the wild.

Captive breeding programs face major challenges to achieve the best conservation outcomes, particularly high economic costs, and loss of vital genetic diversity from wild populations after even a few generations in captivity.

Our economic and genetic modelling published today shows how freezing genetic material and using assisted reproduction could provide a much-needed support-tool for captive breeding programs, solving genetic and economic issues and allowing zoos to breed more species and expand their valuable work.
