Abstract
Postimplantation as well as preimplantation pregnancy in prairie voles can be terminated by replacing the original stud male with an unfamiliar male. The pregnancy is disrupted by the ensuing male-induced estrus. Females spontaneously abort their litters, become receptive, and successfully breed again 4 or 5 days after introduction of the new male.Keywords
