Coils: Copper or Hormone Intrauterine Contraception

Sexual Health D&G offer insertion / changes of intrauterine devices (coils) for contraceptive reasons. If you wish to use a hormone coil for control of your bleeding or as part of a hormone replacement therapy regimen and you are not in need of contraception, please discuss this with your GP/ANP/practice nurse. Insertion of hormone coils for bleeding control and as part of hormone replacement therapy should be done in primary care; if that is not possible, the doctor or nurse you see in primary care should refer you to gynaecology.

There are 2 types of intrauterine contraception (IUC) which are small plastic devices placed in the womb by a trained clinician

  1. Copper intrauterine device (IUD) contains copper which prevents sperm from reaching an egg and it makes it difficult for a fertilised egg to settle in the womb (prevents implantation).
  2. Intrauterine system (IUS) releases the hormone progestogen, which prevents the sperm reaching an egg. It also prevents an egg settling in the womb (implantation). The levels of hormone reaching the blood stream are very low.

For information on intrauterine contraception we recommend that you watch this short film (from NHS Lothian), as it gives you all the information you need about intra-uterine methods. Alternatively read the information below.

Comments

If you are under 25, have a new sexual partner or more than one sexual partner in the last year then you will require testing for chlamydia and gonorrhoea before or at the time of insertion. If you have a discharge or any symptoms the IUD would not be put in until we have the results. Women are taught to feel the threads in their vagina to check the position. If there is a risk of pregnancy it cannot be inserted except the copper IUD can sometimes be inserted as emergency contraception
