Sudan was used as a poster-boy by Ol Pejeta Conservancy (OPC) during a fund-raising campaign that was performed previous year with Tinder, in which the white rhino was received the title of "the most eligible bachelor in the world" and proceeds from which would go toward research on artificial reproductive techniques for the animals.

World's last male white Rhino, Sudan, died in Kenya's Ol Pejeta Conservancy on March 20.

Sudan, 45, was being treated for age-related health issues and a series of infections.

The veterinary team said they had chose to put Sudan to sleep after his condition worsened over the weekend, leaving him with bad skin wounds.

Eventually, as the zoo suffered financial woes and the rhinos failed to breed, Sudan was thankfully moved to the Ol Pejeta Conservancy, in Laikipia County, Kenya, where he lived for the last 9 years of his life.

Hopes of saving the species now lie with Najin, 27, and her daughter, Fatu 18 - which are both at Ol Pejeta.

"One day, his demise will hopefully be seen as a seminal moment for conservationists worldwide", Vigne added.

The northern white rhino used to live in wide areas of central Africa, including Uganda, Central African Republic, Sudan and Chad, but has been considered extinct from the wild since 2008. Scientists may either use the sperm to artificially inseminate one of the surviving females (even though they're related) or, due to their age and ailments, fertilize one of their eggs and implant the embryo into a female of a similar subspecies, like the southern white rhino, using in vitro fertilization. The hope for in-vitro fertilization (IVF) technique has been proposed to preserve the subspecies. "While prices of rhino horn are falling in China and Vietnam, poaching for horn still threatens all rhino species", said Peter Knights, CEO of environmental organization WildAid.

Sudan has served as a global ambassador for his species, appearing in campaigns and public service announcements, and making appearances alongside public figures like pro basketball player Yao Ming.

He did manage to sire two females while at the Czech zoo.

The last surviving northern white male rhinoceros of the world, named Sudan, breathed his last on Tuesday. He spent his time there with two northern white rhino females, Najin and Fatu. Then, the park staff isolated the males to let the females mate with southern white rhinos and at least intercross the species, but didn't have success with that either.

After years in bondage, Sudan at long last figured out how to wind up a rhino at this conservancy, Thaida accepted. "It may sound unbelievable, but thanks to the newly developed techniques even Sudan could still have another offspring".

Due to advanced age, Sudan was unable to reproduce with the planet's two last remaining northern white female rhinos.
