Comparative evaluation of three Tactylon(TM) condoms and a latex condom during vaginal intercourse: breakage and slippage.
This study compared breakage and slippage rates of three male condom styles made of Tactylon(TM), a synthetic elastomer, to those of a marketed latex condom during vaginal intercourse. Safety and acceptability outcomes were also assessed. This two-center, prospective, crossover study enrolled 443 couples. Each couple was randomly assigned to use three condoms of each type in one of 24 use sequences. Couples completed questionnaires after using each condom, all of one condom type, and all four condom types. The percentage and standard error (SE, in parentheses) of latex condoms with clinical breakage was 0.86% (0.295). Percentages for Tactylon condoms were not equivalent to the latex study condom, ranging from 3.50% to 4.17%. The percentage and SE of latex condoms with complete slippage was 1.11% (0.328). Percentages for Tactylon condoms were equivalent to those for latex, ranging from 0.70% to 1.31%. The Low-Modulus Tactylon condom was the most preferred. Fewer medical events were reported with the Tactylon condoms than with the latex condom. It was concluded that Tactylon condoms were equivalent to the latex condom in terms of slippage but not breakage. However, safety and acceptability seemed to be better for Tactylon condoms. This may improve consistency of use and may attract new users.
