A Multicenter, Open-Label, Non-Comparative Study of the Safety and Contraceptive Efficacy of the Woman's Condom

This is a Phase III multicenter, open-label, non-comparative trial of the Woman's Condom to evaluate contraceptive efficacy as the primary method of contraception. Secondary evaluations include safety assessment, incidence of UTIs, symptomatic vaginal infection, performance of the Woman's Condom (clinical breakage, slippage, misdirection, and invagination) and overall acceptability of the product. We will perform a Substudy to assess the semen biomarker as a means of detecting product failure in a subset of subjects.
