What is the copper coil done with?

The device sits in the womb, with thin threads passing through the cervix into the top of the vagina. Copper changes the local environment so sperm movement and fertilisation are disrupted. It contains no hormone. The shape and size of the device can vary, but the copper component is the feature that gives this contraceptive its action. It does not protect against sexually transmitted infections.

Tell the clinician about possible pregnancy, pelvic infection, unusual bleeding, allergies, and any concerns about pain or fainting. After insertion, learn how to check for the threads if advised. Cramping and a change in menstrual flow can happen while your body adjusts. Keep the follow-up plan provided by the clinic and discuss removal if you want a different contraceptive or are planning pregnancy.

Contact a healthcare professional promptly for severe or worsening pelvic pain, fever, unusual discharge, heavy bleeding, pain during sex, or concern that the device has moved. Seek urgent care if you feel faint with severe pain or bleeding. A missed period with pregnancy symptoms also needs assessment because pregnancy with an intrauterine device requires prompt medical review.

Ask how the copper coil works, what insertion feels like, how to check the threads, which bleeding changes are expected, and when the device should be checked or removed.
