Biobanking and fertility preservation for rare and endangered species
Open accessAbstract
For more than 25 years, systematic gathering and cryo-storage of biomaterials from diverse wild species have been ongoing to save gene diversity and improve captive (ex situ) and wild (in situ) animal management.Cryo-storage of biomaterials offers broad opportunities -from helping understand the fundamental biology of unstudied species to enhanced conservation breeding, genomics and veterinary medicine.While promoted for decades, the banking of germplasm, tissue, blood and DNA from wildlife species only recently has been considered by some to be a core function of animal conservation programs.Importantly, reproductive biotechnologies and fertility preservation are critical tools for saving and maintaining endangered species and are tightly related to biobanking.Some successes have been reported with the use and integration of artificial insemination (with fresh or frozen-thawed semen) in conservation programs.However, not a single wild species is currently managed through oocyte freezing or embryo-based technologies.This is primarily due to the lack of knowledge of species biology, as well as inadequate facilities, space, expertise, and funding needed for their successful application.More fundamental studies on animal reproductive biology as well as more fertility preservation options are needed with all parties involved (reproductive technologists, zoo biologists and conservationists) adopting parallel efforts to sustain wild populations and habitats

The existence of biobanks and available germplasm from endangered and extinct-in-the-wild species creates opportunities to reintroduce genetic potential that does not currently exist in the extant population.
“The existence of biobanks and available germplasm from endangered and extinct-in-the-wild species thus creates opportunities to reintroduce genetic potential that does not currently exist in the extant population [88][89][90][91].”
From The Concept of Agency, Animal Wellbeing, and the Practical Realities of Ex Situ Breeding Programs in Zoos and Aquariums (2024) · cites this paper as [91]
In “The value of wild animal biobanks and reproductive biotechnologies” (page not provided), the paper says stored germplasm can be infused into a living population decades later, helping preserve genetic diversity. This supports the opportunity described for endangered species, but the passage does not specifically address germplasm from species extinct in the wild. (LLM, conf=0.83)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
