Abstract of the Disclosure A method and apparatus is provided for non-surgical reversible sterilization of females. An apparatus to which a removable tip is attached is inserted into the uterus. The tip is aligned with the uterine end of the oviduct. A curable elastomeric composition is injected, through an aperture in the tip, into the oviduct in an amount sufficient to fill the portion of the oviduct adjacent to the uterus. The tip is larger in diameter than the uterine end of the oviduct and substantially seals the end thereof during the filling of the end portion of the oviduct with the liquid elastomeric composition. The elastomeric composition is allowed to solidify and adhere to the tip to form the oviduct block. The apparatus is then removed with the tip being ejected from the apparatus so as to remain adhered to and part of the resulting oviduct block. The above procedure is repeated for the oppo- site oviduct. The resulting oviduct blocks prevent the passage of ovum from the ovaries to the uterus and sperm from entering the oviduct thereby pre- venting conception. The oviduct blocks if desired can be removed non- surgically by utilizing an apparatus which grips the larger tip portion of the oviduct block within the uterus and extracts the entire oviduct block from the oviduct.
