The reproduction of polar bears is the only time they hibernate. Mating season occurs from late March to May. Many polar bears don’t actually get pregnant at the time of breeding but instead, they have a delayed gestation. This gestation, or pregnancy, process takes about 60 days unlike the 9 months needed for human reproduction. They look for maternity dens in October or November. These dens are located on land and are mostly only where snow accumulates. They have about 1-2 cubs.These cubs only weigh about 1 pound. They are also about 14 inches long.
