Intrauterine Device (IUD)

The IUD is a long lasting method of birth control that is inserted into the uterus (womb). It is a T-shaped plastic frame that is surrounded by a thin copper wire. At the bottom of the IUD there is a string.

How does it work?

• Makes the lining of the uterus not ideal for a pregnancy.
• Copper in the IUD causes changes in the uterus which destroys sperm.

Advantages

• Can remain in the uterus for three to ten years depending on which IUD is put in.
• No daily routine required.
• Does not contain hormones.
• Is okay for breastfeeding women to use.
• Can be used as a form of emergency birth control if it is put in within 5 days of unprotected sex.
• Does not interfere with sex.

Considerations

• May have irregular bleeding and spotting after insertion.
• Cramping and menstrual period flow may increase.
• Small number of users will have their IUD come out on its own.
• A monthly string check is recommended after menstrul period.

How to use an IUD

The IUD must be put in and taken out by a trained health care professional.
