There are many technical challenges remaining before the team can save the Northern White Rhino from extinction. “ Every additional embryo increases the probability of getting a pregnancy … The more, the better! ” Seet said. ”Īs the last two females are unable to become pregnant, the plan now is to implant the embryos into surrogate female southern white rhinos, a distinct subspecies, in the coming months. Nevertheless, we have achieved the production of a third embryo now. “ Before the BioRescue team came, no one had ever created an embryo from a northern white rhino except for the rhino itself, ” Steven Seet, Head Public Relations & International Affairs at the Leibniz Institute for Zoo and Wildlife Research, told me. The team managed to create two embryos in September 2019 and has recently created a third. They then artificially fertilized the eggs using sperm taken from now-deceased male rhinos and stored the embryos in liquid nitrogen. The BioRescue team, including researchers based at the Leibniz Institute for Zoo and Wildlife Research, Germany, extracted egg cells from the ovaries of the last two remaining northern white rhino females. An international collaboration called BioRescue has taken a step forward in bringing back the Northern White Rhino with the creation of three embryos, which it hopes to bring to term in a surrogate in the coming months.
