Intrauterine Device (IUD)
What is it?
A small T-shaped plastic device that is wrapped in copper wire. The copper changes the environment of the uterus so that it is hostile to sperm. It does not harm the uterus or any other part of your body and does not affect ovulation. The IUD is inserted into your uterus by a healthcare professional. Attached to the IUD are two inch-long threads that hang down through the cervix (the opening to the uterus) and into the top of the vagina.
How do you use it?
An IUD must be inserted by a healthcare professional. An IUD is put into your uterus and the strings are cut just below your cervix. Check the strings after each period. If you can feel the plastic part or the strings are missing, use another form of birth control such as condoms and spermicide until you can see your doctor. Never attempt to remove the IUD yourself. Period-like cramping and spotting is common within the first 3 months of insertion.
The IUD can also be used as an emergency method of birth control. For up to 5 to 8 days after unprotected vaginal intercourse, you can have an IUD inserted to help prevent pregnancy.
Where can you get it?
You can often have an IUD inserted by a healthcare professional at a walk-in clinic, community health centre, or the Sexual Health Centre. If you have a family doctor you can ask them if they are able to insert IUDs.
How much does it cost?
A copper IUD costs between $60-$80 at a pharmacy. It can also be bought for a reduce price at the Sexual Health at 179 Clarence Street.
How effective it is?
Copper IUDs are 98% effective in preventing pregnancy.
Does it reduce the risk of STIs?
No. The IUD does not reduce the risk of sexually transmitted infections.
