The lectins immobilize the sperm to render them incapable of fertilization and also bind to the microorganisms to render them non-pathogenic or to the cells to prevent infection by the microorganisms. Lectins can also be administered to treat sexually transmitted vaginal infections. The invention also encompasses a device for to be placed in the vault of the vagina which comprises a ring which surrounds the cervix and a membrane spanning the central aperture of the ring to prevent the direct contact of ejaculate with the cervical tissues. The device is impregnated or coated with lectins and releases them into the vaginal environment over a period of time.Field of SearchVENERAL DISEASEPeptide containing (e.g., protein, peptones, fibrinogen, etc.) DOAI Produced by or extracted from animal tissue Heavy metal containing (e.g., hemoglobin, etc.) Glycoprotein (carbohydrate containing) Plant extract or plant material of undetermined constitution Gonorrhea Syphilis Virus VAGINAL SHAPED FORMS ADAPTED FOR NONINGESTIBLE USE OTHER THAN SUPPOSITORY TYPE (E.G., FILMS, INSERTS, ETC.)
