Abstract
The increased incidence of human immunodeficiency virus infection in women has identified an urgent need to develop a female-controlled method to prevent acquisition of human immunodeficiency virus and other sexually transmitted diseases. Women would apply the product intravaginally before intercourse. Development of such a product requires a better understanding of the permeability characteristics of the tissues with which such products would come into contact. However, limited studies have been performed in this area. In the present study, water permeability of fresh human cervical and vaginal tissue was evaluated. The average apparent permeability coefficient was found to be 8Â ÃÂ 10â5Â cm/s for fresh human cervical tissue and 7Â ÃÂ 10â5Â cm/s for fresh human vaginal tissue. Considering the lack of regularity in obtaining cervical and vaginal tissue from surgical specimens, additional tests were performed to evaluate the effect of freezing on tritiated water permeability. No statistically significant differences were observed in the permeability values obtained when comparing fresh versus frozen tissues.
