A Mirena IUD lasts 5 years actually. IUD = Intrauterine device, costs few hundred dollars, not entirely sure, but probably ~ 300? Most commonly nowadays IUD contain locally releasing hormones, such as Mirena. The failure rate of birth control pills is up to about 3% per year due to imperfect use. The failure rate of IUD is only about 0.2%. A family doctor can place an IUD, but some will refer to a gynecologist.
