Condom shape: a neglected factor influencing use and acceptability? UK Family Planning Research Network.

Improving condom acceptability amongst users is one way to enhance efficacy. This study aimed to test whether or not the shape of a condom influenced users' perceptions of condom acceptability as measured through their ratings of condom comfort, sensitivity and security. Four types of condoms were tested which had 3 different shapes, and one of which also had a small diameter. Participants were recruited at 15 UK Family Planning Research Network Clinics and one Student Health Centre in England and Wales in late 1997. A total of 1193 people initially volunteered to take part and of these 204 men and 251 women completed the trial, giving an overall response rate of 38%. Results suggest that both men and women were able to detect differences in the shapes of the condoms and that differences led to preference for a particular condom type. Similar proportions preferred a straight-sided, a flared and a contoured condom, whilst the smaller, contoured condom was preferred by a minority of respondents. To optimize consistent condom use, providers should consider encouraging users to try a range of condoms to ensure that they are using the one most suitable for them.
