This study will investigate a new plastic insertion device which has been developed to insert an intrauterine contraceptive device (known as an IUD or coil) into the womb immediately after childbirth. We want to know if this new inserter might make the procedure even easier to perform and more comfortable for patients than the current standard technique (which involves using metal ‘tongs’ to insert the IUD). If the study is successful, the plastic inserter could become available to use in the NHS. This could help to make the IUD a more easily available contraceptive option for women after childbirth. You might be able to take part in our study if you are:16 years of age or overCurrently pregnant and planning vaginal birthWishing a coil for future contraception (hormonal or non-hormonal)Willing to have your coil inserted after birth by one of two methods: the standard technique (metal 'tongs') or new insertion deviceWilling to attend a follow-up visit 6 weeks after birthMore information can be found on our Patient Information Sheet (PIS): Document POP-IN study Patient Information Sheet (691.74 KB / PDF) About the study Dr Michelle Cooper explains the study and how coil insertion works ContactFor further information contact Research Midwife Karen McCabe:Phone/text: 07973760871Email: chalmers.research@ed.ac.uk This article was published on 2026-04-15
