Recently inseminated female deer mice were exposed to changes in physical environment, including size of available space, newness of environment, and a stud or strange male in order to test the hypothesis that a strange male decreases the incidence of pregnancy in recently inseminated females (Bruce effect). The data confirm the Bruce effect but also indicate that changes in physical environment produced great effects on implantation in recently inseminated females.
