The female condom is a disposable device that has two flexible rings at either end of a soft, loose-fitting polyurethane sheath. It is 75% effective as a birth control method and as a preventive measure for venereal disease. It is inserted like a tampon, with the inner ring covering the cervix and the outer ring remaining outside. After intercourse, the condom should be removed by first squeezing and twisting the outer ring to hold the semen in the pouch.
