Women in Kananga, Zaire, sometimes insert substances into the vagina to enhance sexual pleasure. The objective of this study was to ascertain: 1) what intravaginal substances are used, 2) the prevalence and frequency of their use, and 3) the visible effects they produce on the female genitalia. Focus group discussions with women and men were conducted, and both prostitutes and non-prostitutes were interviewed individually about their sexual preferences and practices. The cervices and vaginae of eight women were inspected and photographed before and after the insertion of commonly used substances. It was found that Kananga residents preferred a "dry-tight" vagina during coitus. They named thirty substances (leaves and powders) that women insert to produce this sensation. Twenty-one of 50 prostitutes (42%), and 17 of 49 non-prostitutes (35%), had used such intravaginal substances. Inspection of the genitalia showed that five different leaves produced inflammatory reactions that lasted up to a week. These genital irritations might facilitate the transmission of pathogenic organisms. Investigators elsewhere should study the use of intravaginal substances and their relationship to sexually transmitted diseases.

Background Because male circumcision has been linked to a lower risk of HIV infection, it is advocated tentatively as a possible preventive intervention. Most studies, however, have relied on men's self-reports of their circumcision status. Goal To document varied techniques of male circumcision in one area of Kenya and the visible results. Study design Researchers interviewed men who had performed or undergone various forms of circumcision. They also did genital observations on a subsample of respondents. Results All the men reported undergoing circumcision during adolescence, and most were able to tell which technique was used. According to the circumcisers, in type A, approximately 4 cm of the prepuce is removed; in type B, 1 to 2 cm of the prepuce and some of its inner surface are removed. Types A and B result in the same genital appearance. In type C, 1 to 2 cm of the prepuce and some of the inner surface are removed. The remaining prepuce is slit and suspended below the penile shaft. Conclusions Asking a man "Are you circumcised?" is not sufficient. Classifying his circumcision status requires both a genital examination and an understanding of the precise local surgical techniques used. Even in a small geographic area, considerable variety may exist in the techniques of cutting, removing, altering, or leaving different portions of the foreskin. Each variation may affect the transmission of HIV and other infections.

Objective To review reports on the use and effects of traditional intravaginal substances and practices. Method The medical and social science literature of the past 50 years regarding use and effects of traditional intravaginal substances and practices is reviewed. Results Traditional intravaginal practices have been described in 11 countries of sub-Saharan Africa, and also in Qatar, Indonesia, Thailand, Haiti, the Dominican Republic, and the United States. Women's reasons for the practices include personal hygiene, disease prevention or treatment, and enhancement of sexual experience. Few studies document damage to the vaginal epithelium or changes in vaginal flora due to these practices. No prospective studies link these practices to disease transmission. Conclusion The determination of how these practices affect disease transmission will require precise definition of independent variables, which is difficult because of the diversity of the practices. It is appropriate to search for intervening variables; specifically, the effects on the vaginal pH, flora, and epithelium.
