A prefabricated cervical cap includes a generally dome-like flexible shell of a depth sufficient to receive therein a major portion but not all of cervix uteri and a resilient, form-assuming internal liner for the shell. The liner is integral with the shell and is deformable upon contact with cervix uteri without substantial deformation of a contiguous portion of the cervix uteri. The liner may extend beyond the shell. In a preferred embodiment the cervical cap includes a one-way valve means that accomodates the flow of a uterine discharge without need to remove the cap.
