“…Sperm has been collected postmortem in one wildlife species, the plains zebra ( Equus quagga ), resulting in successful heterologous embryo production after ICSI with frozen-thawed epididymal semen [ 62 , 63 ]. Live horse foals have been born after the insemination of epididymal sperm collected post-castration via retrograde flushing [ 64 , 65 ]. These findings indicate the potential of semen collected postmortem from valuable wildlife for ART and genome resource banking.…”

The collection of gametes from recently deceased domestic and wildlife mammals has been well documented in the literature. Through the utilization of gametes recovered postmortem, scientists have successfully produced embryos in 10 different wildlife species, while in 2 of those, offspring have also been born. Thus, the collection of gametes from recently deceased animals represents a valuable opportunity to increase genetic resource banks, obviating the requirement for invasive procedures. Despite the development of several protocols for gamete collection, the refinement of these techniques and the establishment of species–specific protocols are still required, taking into account both the limitations and the opportunities. In the case of wildlife, the optimization of such protocols is impeded by the scarcity of available animals, many of which have a high genetic value that must be protected rather than utilized for research purposes. Therefore, optimizing protocols for wildlife species by using domestic species as a model is crucial. In this review, we focused on the current advancements in the collection, preservation, and utilization of gametes, postmortem, in selected species belonging to Equidae, Bovidae, and Felidae, both domestic and wildlife.
