Do polar bears have balls?

But we shouldn’t be panicking about extra polar bear testicles, according to Christian Sonne, a biologist at the University of Aarhus in Denmark who has studied the impacts of chemicals on the bears. “Two sets of testicles have never been found in polar bears,” Sonne wrote to Newsweek.

Can polar bears be pregnant?

Although polar bears mate during the spring season when they’re out on the frozen sea-ice, mother polar bears don’t actually become fully pregnant until the autumn. They undergo something called “delayed implantation”. This means that the initial fertilized egg stops growing for the next 4 months.

In most areas, pregnant polar bears dig dens deep in snow drifts on land or on the sea ice, where they will wait to give birth during the winter. In Canada, some bears build dens in frozen peat banks. Expectant mothers use these dens to rest and keep warm during the harsh Arctic winters.
