Safety, functionality and acceptability of a prototype polyurethane condom.

Abstract

Male condoms made from synthetic materials offer an alternative to latex condoms that may be more acceptable to users, thereby potentially resulting in more protected acts of intercourse. A prospective, noncomparative clinical study was conducted to evaluate the safety of using certain polyurethane materials to make condoms. Fifty-one healthy, contracepting, mutually monogamous couples were recruited between June 30 and November 24, 1993 to use a prototype roll-on polyurethane condom developed by Family Health International. Couples were to use the condoms for 10 consecutive acts of vaginal intercourse over a 4-week period. Baseline and postexposure genital examinations, including colposcopy for female participants, were performed. Fifty couples completed the study requirements and 517 acts of intercourse occurred using the condoms. Two adverse events were reported: irritation of introitus in a female participant and a small irritated erythematous lesion on a male participant's penis. Neither event was considered to be serious and both were resolved without treatment. Breakage and slippage rates were similar to those reported for latex condoms. These results suggest that polyurethane condoms represent a safe, functional and acceptable alternative to latex condoms.
