Abstract

Objectives: This study compared the condom failure rate, safety and acceptability of two new synthetic adhesive male condoms, Wondaleaf-Cap® (WLC) and Wondaleaf-On-Man® (WLM), with a marketed latex external condom Durex®-Together (DT). Study design: We enrolled healthy married, monogamous, heterosexual condom users in a randomized controlled, cross-over, pilot trial in Malaysia. We randomized participants to six groups with different condom use-orders of the experimental WLC and WLM and control latex condom for four episodes for vaginal sex over 1 month for each condom type. We summarized the clinical and non-clinical failure rate, safety and acceptability of each condom type using descriptive statistics. We tested differences in condom failure and acceptability using generalized estimating equations and repeated measure ANOVA respectively. Results: We screened 75 couples and randomized 50 eligible couples. Two couples withdrew before receiving any condom. The remaining used 576 condoms with 192 uses for each condom variant. Clinical failure rates of WLC, WLM and DT were 1.04%, 0% and 0.52%, respectively. Non-clinical failure rates of WLC, WLM and DT were 2.08%, 3.12% and 1.04%, respectively. Removal was found more painful with Wondaleaf products than the DT. Preferences of participants for WLC, WLM and DT were 33.3%, 29.2% and 25%, respectively. Overall, WLC and DT had greater acceptances among male participants than WLM. Conclusion: Results of this pilot study support that use of synthetic adhesive male condoms is associated with failure rates similar to those seen with existing latex, and with greater acceptability. A larger study to ascertain non-inferiority is underway. Implications: The availability of synthetic adhesive male condoms may increase the acceptability of condom use. However, removal pain and clinical performance requires further study.
