Protocol Title:  Gel Product Attribute Study

Status:  Completed


The PAS I study was conducted among 543 women at seven locations in Kenya, South Africa and Zambia with the aim of assessing whether vaginal gels will be acceptable to, and used by, women in Africa.

The women participating in the study were asked to use the three placebo gels (without active ingredient) of low, intermediate and high viscosity and provided feedback on each through a series of in-person interviews conducted during the course of the study.

Some participants' male partners were invited to share their opinions on the gels the women used.

Results from PAS I showed some differences between the preferences of women in different countries likely as a result of varying cultural norms and level of comfort women had when speaking about sex. 

Overall, women in the study preferred the medium viscosity gel while the low viscosity gel was least favored.
