US-based chiropractor Daniel Dopps has invented a "lipstick" that will glue the vagina shut during menstruation. Dopps said applying Mensez seals the vagina and holds menstrual blood, which is released when a woman urinates. "Mensez is a proprietary combination of amino acids and natural oils in a lipstick applicator," its website says. The patent for Mensez was granted in January.
