Developing Rectal USPE Measures

The purpose of this study is to: (a) adapt existing vaginal USPE items/instruments for evaluation of similar elements of rectal compartment use; (b) develop these scales using 3 distinct semi-solid formulations that represent a range of physicochemical and rheological properties of microbicides that are currently being designed for dual compartment use; and (c) develop novel USPE instruments to capture the experience of product use in the context of receptive anal intercourse (RAI) in both male and female cohorts.
