Design A comparative trial following patient-blinded randomisation in an outpatient clinic setting. Method Women requesting an IUD for emergency contraception were fitted with either a GyneFix or a Gyne-T380S®. For those requesting removal of the IUD, visual analogue scores were used to assess their perception of the associated pain, and a Newton dynamometer was used to measure the force required to remove the device. Results Removal required significantly more force for GyneFix as compared with Gyne-T380S (p = 0.004), but there was no significant difference in pain perceived by women during removal. Interestingly, anticipated pain was worse than actual pain experienced. Conclusion Although more force is needed to remove the GyneFix as compared with the Gyne-T380S, this does not translate into more pain.
