Advantages and disadvantages of intrauterine devices (IUDs)

The following table lists the advantages and disadvantages of using intrauterine devices (IUDs) as a birth control method.

Consideration

IUDs

Advantages
  • More than 99% effective in preventing pregnancy1
  • Most cost-effective method of birth control over time
  • Easy to use
  • Does not require interruption of foreplay or intercourse
  • Does not require co-operation of sexual partner
  • Safe to use while breast-feeding
  • Can be removed whenever you have problems or want to stop using it. Fertility returns with the first ovulation cycle following IUD removal.
  • Progestin (LNg IUD) relieves heavy menstrual bleeding and cramping in most women
  • Copper IUD can be used for emergency contraception within 5 days of unprotected intercourse
  • Can be inserted after a normal vaginal delivery, a caesarean section, or a first-trimester abortion
Disadvantages
  • Costs several hundred dollars for insertion. (Some community clinics may offer insertion and removal at a reduced rate or free to low-income clients.) If the IUD is expelled, it costs just as much to get a new one. Having an IUD removed is also costly. The costs of IUD insertion and removal may be covered by your provincial health plan.
  • Only a health professional can remove the IUD. Never attempt to remove the IUD yourself or allow a partner to try to remove it.
  • Does not provide protection against sexually transmitted infections (STIs) or HIV. (A condom is needed for STI protection.)
  • When inserted, can spread a genital infection into the uterus, leading to pelvic inflammatory disease (PID) in the first months after insertion. This is why you are screened for STIs before getting an IUD.
