Bears as Induced Ovulators: A Preliminary Study

We visually verified corpora lutea and measured serum progesterone concentrations during the estrous cycle in 8 semi-captive black bears (Ursus americanus) in South Dakota. Our data suggested that black bears ovulate after they mate, indicating that black bears are induced ovulators. These preliminary findings may aid scientists in their efforts to save endangered bear species through controlled breeding programs.
