A new concept of pregnancy and disease prevention is provided by a medicated tampon in the form of a soft, porous foam ball, which is easily insertable into the vagina to cover the cervical area and which is impregnated with a safe spectrum of antibiotics for control of venereal disease and with a contraceptive for control of pregnancy. The tampon may be inserted before intercourse to remain in place during intercourse.
