What should you know about a copper tube coiling machine?

A copper coil, also called a copper IUD or the coil, is a small device fitted inside the womb by a trained healthcare professional. It releases copper, which interferes with sperm movement and fertilisation. It does not contain hormones. The device has fine threads that extend through the cervix into the vagina, allowing a clinician to check its position and remove it when needed.

Some people notice heavier bleeding or stronger cramps after fitting, particularly during early periods. Others have little change. A copper coil does not protect against sexually transmitted infections, so condoms may still be useful depending on your situation.

Arrange a consultation with a qualified clinician to discuss your menstrual pattern, medical history, pregnancy possibility, and contraception needs. They can explain the fitting process, check whether this option is suitable, and discuss alternatives such as a hormonal coil. Do not try to insert, adjust, or remove the device yourself.

After fitting, learn how the threads normally feel if your clinician recommends checking them. Keep any follow-up appointment and seek advice if the threads feel different, you cannot feel them when expected, or you think the device has moved.

Contact a healthcare professional promptly for severe or worsening lower-abdominal pain, fever, unusual or foul-smelling discharge, very heavy bleeding, or pain during sex after fitting. Seek urgent medical help if you have intense pain, feel faint, or think you may be pregnant while the coil is in place. These symptoms need assessment because they can signal infection, displacement, or another condition.

You could ask: How would a copper coil affect my periods? What should I expect during and after fitting? How will I know if it has moved? When should I return for review? What contraception or sexually transmitted infection protection should I use alongside it?
