The polar bear called Sedov has been at the Krasnoyarsk zoo since 2004, coming there from a zoo in St. Petersburg when he was just two years old.
A zoo in Stary Oskol, in the nearby Belgorod region, has requested Sedov be sent there in an attempt to mate with a female bear living there, RIA Novosti reported.
Sedov will stay in his new home in Stary Oskol with his new partner for three years, officials said.
"Three years is, according to zoologists, the period in which offspring can appear among polar bears," a Krasnoyarsk zoo official said.
"If offspring appear earlier, then Sedov will go home earlier," she said.
Any offspring would be shared between the two zoos, the official said, assuming there are at least two. "If we get an odd number, one of the zoos will pay the other zoo," she said.
