In Kenya’s Laikipia County, a desperate fight is unfolding to save one of the planet’s most critically endangered species. At the Ol Pejeta Conservancy, the last two remaining Northern white rhinos, Najin and her daughter Fatu, live under round-the-clock protection.
With no surviving males and no ability to reproduce naturally, the species is functionally extinct. Yet, hope remains in a surprising source: in-vitro fertilization (IVF).
This groundbreaking approach may be the only way to prevent the Northern white rhino from disappearing forever. However, it’s a race against time, with challenges.
The Last of Their Kind
Najin and Fatu are symbols of a vanishing world. Decades of poaching and habitat destruction have pushed their kind to the brink. Today, they live under armed guard, shielded from a humanity that has both destroyed and now seeks to save them.
The Northern white rhino is technically extinct, incapable of sustaining its population naturally. With no males left and Najin and Fatu unable to carry pregnancies. The survival of the species hinges on science.
Progress in IVF For Rhinos
Scientists working with the BioRescue team have made remarkable strides in IVF for rhinos. Over the past few years, they’ve harvested 29 oocytes from Najin and Fatu. These eggs were carefully transported to Italy, where researchers successfully matured them into embryos.
IVF technology has seen success in closely related species. In a world-first, scientists achieved a Southern white rhino pregnancy through embryo transfer. The embryo was developed in a lab and implanted into a surrogate. This milestone demonstrates that the process is possible—but applying it to Northern white rhinos adds layers of complexity.
“This is a critical step forward,” said a researcher involved in the project. “We now have a clear path to saving the species, but the clock is ticking.”
The High Stakes of Innovation
Despite these advancements, the challenges are immense. A previous attempt at IVF ended in tragedy when a surrogate mother died just 70 days into her pregnancy due to a bacterial infection. This loss underscored the fragility of the process and the risks involved.
Adding to the complications, Najin and Fatu are not suitable candidates to carry pregnancies themselves. This means researchers must rely on Southern white rhinos as surrogates. While this species is more abundant, finding healthy and compatible candidates is a painstaking task.
“There’s no room for error,” said another scientist on the project. “We’re working with an extremely limited genetic pool, and every step has to be executed perfectly.”
A Plan for the Future
Despite these setbacks, researchers are pressing forward with an ambitious plan: to create and implant Northern white rhino embryos into Southern white rhino surrogates. The hope is to produce calves while Najin and Fatu are still alive, ensuring a living connection to their species’ lineage.
Each embryo represents a lifeline for the Northern white rhino. The ultimate goal is to establish a small but viable population that can eventually be reintroduced into the wild. However, even in the best-case scenario, this is a process that will take decades.
In the meantime, Najin and Fatu’s genetic material is being preserved. Scientists are also exploring new technologies, such as stem cell research, to broaden the scope of what’s possible.

Beyond the Lab
The fight to save the Northern white rhino isn’t just happening in labs—it’s unfolding on the ground in Kenya, where conservationists are ramping up anti-poaching measures. These efforts include the deployment of advanced technologies, such as drones and surveillance systems, alongside increased law enforcement presence.
At policy level, Kenya has introduced stricter wildlife protection laws to deter poachers. These measures aim to safeguard not only rhinos but also the country’s broader ecosystem, which is home to countless other threatened species.
“We’re not just fighting for one animal,” say conservationists. “We’re fighting for the entire web of life that depends on a healthy, balanced environment.”
The Broader Implications
While the stakes are undeniably high for the Northern white rhino, the success of this project could have far-reaching implications. If scientists can perfect IVF and other assisted reproduction techniques, these methods could be applied to other endangered species around the world.
The project also raises important ethical questions. As humans push the boundaries of science to save species, what responsibilities come with this power? And how do we ensure that we address the root causes of extinction, not just the symptoms?
A Glimmer of Hope
The journey to save the Northern white rhino is far from over. It’s a fight fraught with challenges, heartbreak, and uncertainty.
For Najin and Fatu, the clock is ticking. But thanks to the tireless efforts of scientists, conservationists, and policymakers, their story may not end in extinction. It may instead mark the beginning of a new chapter—not just for their species but for the future of conservation itself.
