The T-shaped models with a surface area of 380 mm 2 of copper have the lowest failure rates. The TCu 380A (Paragard) has a one-year failure rate of 0.8% and a cumulative 12-year failure rate of 2.2%. [10] Over 12 years of use, the models with less surface area of copper have higher failure rates. The TCu 220A has a 12-year failure rate of 5.8%.
The hormonal IUD is an extremely effective method of birth control, and a 2021 study demonstrated that it may be used for emergency contraception. [15] In addition to birth control, the hormonal IUD is used for prevention and treatment of: Heavy menstrual periods [16] Endometriosis and chronic pelvic pain [16] [17] Adenomyosis and dysmenorrhea ...
Women over age 20 and those who have previously given birth are placed in category 1, meaning no special concerns are placed on use. [63] [64] Some women experience amenorrhea, or lack of menstruation while using an IUD.

Walgreens, CVS, Walmart and many other retailers carry Plan B, which can be purchased over the counter. A Plan B pill typically costs around $50, but off-brand options can be cheaper.
The failure rate of a copper IUD is approximately 0.8% and can prevent pregnancy for up to 10 years. The hormonal IUD (also known as levonorgestrel intrauterine system or LNg IUD) releases a small amount of the hormone called progestin that can prevent pregnancy for 3–8 years with a failure rate of 0.1-0.4%.

IUD use carries some additional risks. Both hormonal and non-hormonal IUDs may lead to developing non-cancerous ovarian cysts. [21] [25] It is also possible that an IUD may be expelled (fall out) from the uterus. [26] The IUD may also perforate (tear) the uterine wall. This is extremely rare and a medical emergency. [27]
