What should you know about copper strip in coil?

A copper IUD has a small plastic frame with copper around part of it. The copper acts locally in the uterus, affecting sperm movement and fertilisation. This is why the method works without releasing contraceptive hormones into the body.

The copper component is part of a complete medical device, not a strip that is placed separately. A clinician inserts the device through the cervix and leaves fine threads for checking and removal. It does not prevent sexually transmitted infections.

Before fitting, discuss your usual bleeding, cramps, pelvic symptoms, pregnancy possibility, and any history that may affect suitability. Ask the clinician to show or describe the device and explain insertion, removal, and pain-relief options.

Follow the aftercare advice and observe your symptoms. Some people experience cramping or heavier bleeding after fitting. Keep the contact details for the clinic and ask how to check the threads if that is part of your plan.

Contact a healthcare professional promptly if you develop worsening pelvic pain, fever, faintness, unusual-smelling discharge, very heavy bleeding, a positive pregnancy test, or threads that disappear or feel different. Sudden severe pain needs urgent assessment.

Ask how much copper the device contains, how it affects sperm, what bleeding changes are expected, how its position is checked, and which symptoms mean you should return immediately.
