In a world where only two northern white rhinoceroses remain, and both are infertile, scientists have achieved a breakthrough that could rewrite extinction. In Kenya’s Ol Pejeta Conservancy, researchers successfully transferred a lab-grown embryo into a southern white rhino surrogate, creating what may be the first rhino pregnancy via in vitro fertilisation (IVF). Though the surrogate later died from a bacterial infection, an autopsy confirmed a viable embryo, offering proof that the technique can work, according to a report from AP News.
The embryo was created in Europe, using eggs and sperm stored from deceased northern white males, and transferred to Kenya. The surrogate, a southern white female named Curra, was chosen for her physical compatibility. While the pregnancy didn’t carry to term, project leader Thomas Hildebrandt from the BioRescue consortium called it a “proof of concept” moment. He told The Guardian that this success shows IVF could realistically be used to resurrect the species.
Before this, no rhino had ever carried a pregnancy through embryo transfer. The last two northern white rhinos, Najin and Fatu, are both unable to reproduce naturally. The IVF procedure involved harvesting eggs from Fatu and fertilising them with frozen sperm from four deceased northern males. The resulting embryos are stored in labs in Berlin and Cremona, Italy. Scientists now plan to implant them into other southern white surrogates before mid-2024.
@africathrillingsafaris At #olpejeta Conservancy walks a soul that has known loss more deeply than most. His name is Baraka. He is thirty one years old, a black rhino whose life began with promise and quickly learned the meaning of heartbreak. Baraka was the first rhino ever born at Ol Pejeta, a symbol of hope taking its very first breath on protected land. But that hope was brutally interrupted. Poachers took his mother, leaving him to grow up in a world already marked by violence. He never had the chance to follow her footsteps for long, yet her absence shaped every step he took after. As Baraka grew, instinct and survival guided him. Like all black rhinos, he fought to defend his territory. One such battle changed his life forever. A violent clash with another rhino left one eye beyond saving. Veterinarians fought for him, removing the damaged eye and carefully stitching him back together. He survived, learning to face the world with only one eye and a stubborn will to live. To protect him from further fights and from predators, Baraka was moved into a one hundred acre enclosure. It was meant to be his refuge, a place of safety and quiet healing. For a while, it was. Then, just six months later, darkness came again. Cataracts slowly stole the sight from his remaining eye and Baraka became completely blind. Yet Baraka did not give up. Today, he lives in a world built on memory, scent and sound. He knows every corner of his enclosure not by sight, but by trust. He recognizes his caretakers by their voices. He follows familiar paths with a calm that breaks your heart when you realize what he can no longer see. Baraka cannot witness the sunrise over Ol Pejeta. He cannot see the people who protect him or the land he helped make famous. But in his quiet strength, he has become something greater than a rhino. He is a reminder of what poaching steals, of what conflict costs, and of the resilience that still survives in the darkest moments. Baraka walks on, blind yet dignified, carrying a story that demands compassion and protection.

Curra and a teaser bull named Ouwan died after flood-borne bacterial infections swept through the area in late 2023. However, the embryo Curra was carrying, a male fetus measuring 6.4 cm, was developing normally. The team now plans to use other female rhinos, Arimet and Daly, as future surrogates.
Genetic diversity remains a major concern. All embryos created so far have come from the same mother and a small group of male donors. The researchers are considering using gene-editing and even preserved genetic material from museum specimens to widen the gene pool. The ultimate goal is to produce animals that can one day live and breed in the wild.
This project is part of a broader shift in how conservation is approached. A separate Guardian feature highlighted how assisted reproductive technologies such as IVF, stem-cell techniques and embryo transfers are now being explored as tools to support species on the brink. These methods offer a potential lifeline where natural reproduction is no longer viable due to habitat loss, poaching, or population collapse.
While this IVF breakthrough has drawn headlines, conservation groups like Save the Rhino International continue to stress that science alone isn’t the answer. According to AP News, success will also depend on maintaining safe habitats and tackling the root causes of decline.
For a species that once roamed across central Africa in large numbers and is now represented by just two living, infertile females, this is no small step. It’s a fragile but meaningful sign that extinction may not be the end of the story.
