Do male polar bears hibernate?

Female: yes, it seems. But what about the males?

I can't seem to find a definitive answer. I've found information regarding the female polar bears entering a hibernation-type state when they go into their den to give birth, but I can't find anything that says if male polar bears hibernate. Considering they hunt in the winter and the summer periods are relatively short, I'm wondering if they need to.

I believe polar bears estivate--which is hibernating, but during summer.

According to Wikipedia, With the exception of pregnant females, polar bears are active year-round, although they have a vestigial hibernation induction trigger in their blood. Unlike brown and black bears, polar bears are capable of fasting for up to several months during late summer and early fall, when they cannot hunt for seals because the sea is unfrozen

So, active but maybe fasting.

Best answer: Polar bears will reduce their metabolic rate in the summer and will feed opportunistically, but do not hibernate in the way other bears do. Here's a link.
