VCF is a translucent square of material containing the active ingredient Nonoxynol-9, a widely used highly efficient spermicide. Placed high in the vagina as close as possible to the neck of the womb (cervix), it dissolves into a gel which exerts a powerful contraceptive effect against sperm. It is a potent spermicidal agent used successfully by millions of women. Inserted into the vagina before intercourse it need cause no interruption to the beautiful spontaneity of lovemaking. It becomes unnoticeable by either partner. Because VCF is small and unnoticed in use, it can be used discreetly by the woman. It does not run and will not stain. VCF is eventually washed away with the natural body fluids. Spermicides such as VCF can be 94% effective. The best source of information on the use of contraceptives is your family physician or family planning clinic.
