ABSTRACT:
A method and device for birth control which comprises producing an electrical force within the cervical canal of a female for acting on male sperm and preventing migration of the sperm through the cervical canal and into the uterine cavity. The electrical force is provided by a self-contained, sealed battery capable by itself of producing an electromotive force and is inserted within the cervical canal and retained therein over extended periods of use. The device is designed such that it does not impede the free flow of menstrual and other discharges through the cervical canal and is fabricated with or covered by biologically inert material so that it can be retained in place in the cervical canal for indefinite periods as long as desired by the user for birth control purposes. The device is provided with anchoring means which are designed to engage the wall of the cervical canal for securely holding the device in place within the cervical canal with the electric force producing electrodes so positioned as to be exposed to fluids passing through the cervical canal.
