Females reach sexual maturity between 4 - 7 years old. Mating season is in April, May, and June. The pair stays together for only a few days during the breeding season, and during this time they copulate many times. Female bears are induced ovulators, meaning they have to be stimulated several times in order to ovulate, so this is why they must mate so often. This tie may last for 10 - 30 minutes.
Pairs only remain together to mate, the separate after a week.
Males do not help to raise the young. Cubs are born from November to February. It is not known whether they have the delayed implantation like other bear species. Their eyes open at 42 days old, and they can follow their mother by the time they are 3 months old. These bears are killed for their body parts and fur.
