Abstract

Objectives: The aims of this study were to assess the effects of Lea's Shield® plus nonoxynol-9 spermicide on signs and symptoms of female genital irritation and cervical and vaginal microflora during 8 weeks of use with intercourse and to analyze problems associated with the use of the device. Methods: In this open-label, single-arm study, participants were evaluated by pelvic examination, colposcopy and vaginal and cervical cultures. Results: About 13% of women (4/30) reported symptoms of irritation, and minor product-related colposcopic findings were seen in about one third (11/30). Although average colony counts for enterococcus, Escherichia coli and anaerobic gram-negative rods increased during product use, no clinical diagnoses of infection were made. Most users reported at least one problem using Lea's Shield. Conclusion: Lea's Shield, when used for 8 weeks during intercourse, is associated with evidence of genital irritation in a minority of users and with changes in vaginal microflora that do not appear to correlate with clinical infections.
