The BioRescue project develops and pioneers advanced assisted reproduction technologies (aART) for conservation in the face of the imminent extinction of most rhino species and subspecies. In a new scientific analysis published in the journal “Reproduction”, the team evaluated 65 aART procedures conducted from 2015 to 2022. The evaluation showed that aART is safe for the donor females with no detrimental health effects, and successful in that it yielded 51 embryos. In fact, regular OPUs benefited the reproductive health of individual female rhinos.
