Description
Summary: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.
