Sudan, a 45-year-old rhino and the last male of his subspecies (Ceratotherium simum cottoni), is ailing in the wake of two infections on his back right leg, according to Ol Pejeta Conservancy, the wildlife sanctuary in Kenya where the last three northern white rhinoceroses on the planet live.

"At the advanced age of 45, his health has begun deteriorating, and his future is not looking bright," Sudan's caregivers posted on Ol Pejeta's Facebook page. Rhinos usually live between about 30 and 40 years, according to a follow-up comment by the caregivers, and Sudan's problems are age-related.

So many people have supported the northern white rhinos since they arrived on Ol Pejeta in 2009, and we feel it is important to inform you that Sudan, the last male northern white rhino on the planet, is starting to show signs of ailing. At the advanced age of 45, his health has begun deteriorating, and his future is not looking bright.

At the end of the 2017, Sudan developed an uncomfortable age related infection on his ...

To save a rhino
Since then, the population of captive white rhinos has been falling one by one, largely due to old age. In 2014, after the deaths of a male named Suni at Ol Pejeta and a male named Angalifu at the San Diego Zoo, Sudan became the sole surviving northern white rhino male.

Sudan is one of only three northern white rhinoceroses left in the world, period. A female, Nola, died of old age and infection at the San Diego Zoo in November 2015, leaving only Sudan and two females, named Fatu and Najin, at Ol Pejeta. Najin is Sudan's daughter, and Fatu is his granddaughter; both have conditions that make carrying a pregnancy impossible. What's more, in 2015, Sudan's sperm count was discovered to be very low, making him unlikely to father offspring naturally.

Conservationists are using artificial measures in attempts to save the species. For example, they're using sperm and eggs extracted from northern white rhinoceroses, including Sudan and recently deceased individuals, to try to develop rhinoceros in vitro fertilization (IVF). This strategy depends on managing to fertilize a northern white rhinoceros egg in a lab and successfully implant it in a surrogate mother from the southern white rhinoceros subspecies (Ceratotherium simum simum), which was once at the edge of extinction but made a comeback thanks to intensive conservation efforts.
