Cellulose Sulfate and HIV Transmission Among Women

Summary

The purpose of the study is to determine the effect of cellulose sulfate on the transmission of HIV to women via vaginal intercourse. The secondary objectives are the effect on the transmission of gonorrhea and chlamydia via the same route. The study hypothesis is that there will be no effect.
