The best available prevention against sexually transsmitted diseases is limited to a consistent and correct use of a condom by the male. A new barrier method has been developed for the female. As it can be inserted into the vagina before sexual intercourse starts, and as it covers the entrance of the vagina, the opening of the uretra and the root of the penis, it is presumed to give a high degree of protection against sexually transmitted diseases and unwanted pregnancy. The preliminary results concerning acceptability are promising, and futher investigations concerning acceptability and efficacy are in progress or completed in several countries. The method should be regarded as one aspect in the pattern of protection, particularly suitable for females with sexual risk behavior. 1990 Acta Obstet Gynecol Scand
