Are there women who should not use an IUD? This makes IUDs a good form of birth control for many more women. In 2012, the American Congress of Obstetricians and Gynecologists (ACOG) said that both IUDs could be used by teens, unless the teen had a pelvic infection in the past. In 2005, the US Food and Drug Administration said using the copper IUD was okay for women who had never had a child and who had more than one sexual partner. Who can use an IUD?īefore 2005, IUDs were used mainly by women who had at least one child, had no history of pelvic infections and who had a sexual relationship with just one partner. This scarring is mainly linked with chlamydia infection (sexually transmitted infection), and not the IUD itself.
Studies show that a woman using an IUD has the same chance of having scarred tubes as other women with the same number of sexual partners and infections. Also, the chance of not being able to get pregnant due to scarring of the fallopian tubes is no higher than when an IUD is not used. The chance of getting a sexually transmitted infection is the same with or without an IUD. In fact, infection only happens within the 3 weeks after the IUD is put in. Research studies have shown this is not true. In the past, some women in the US have worried about using IUDs because they thought IUDs might cause an infection in their lower belly (pelvis) or prevent them from being able to have a child. What are some of the concerns about IUDs? IUDs are used by 40 out of 100 women in China and 10 to 30 out of 100 women in Latin America and Europe, but in the US only about 6 out of 100 women use IUDs. IUDs do not keep you from getting infections that are passed from one person to anther during sex. IUDs must be put in and taken out by a doctor or nurse practitioner. Most women with a hormone IUD do not bleed as much with their periods and have fewer cramps after the first few months. Hormone IUDs can be used for up to 5 years. It also changes the inside of the uterus so that menstrual bleeding is lighter.
The hormone IUD has progestin, a man-made hormone that thickens the mucus in mouth of the womb (at the cervix) to keep sperm from going into the uterus. The copper IUD is wrapped with coils that put small amounts of copper into the uterus, which harms sperm, and can be left in place for up to 10 years. There are two kinds of IUDs in the US: the copper IUD and hormone IUD. IUDs are small, bendable implants shaped like a T that are put inside a woman’s uterus (womb). LARC methods also help women in other ways and there are very few reasons they cannot be used. The shot fails at a higher rate than other LARC methods because it does not last as long. LARC methods include subcutaneous (under the skin) implants, intrauterine devices (IUDs), and injectable methods (a shot). The number of abortions is also lower when women use LARC. LARC methods reduce the number of times women get pregnant when they do not want to, called unintended pregnancy. Because of this, the failure rate is less than 1 in 100. These methods do not fail as often and fewer women become pregnant because they are always in place and last for a long time. One group of methods that is becoming more popular for many women is Long-Acting Reversible Contraception (LARC).
The pill usually fails because it is not used correctly. Birth control pills fail about 8 to 11 times out of 100 even though most people think the birth control pill keeps a woman from getting pregnant almost all the time. For example, male condoms can fail 1-2 times in 10 uses. Even if birth control is used correctly, some methods will fail. Eighty-five out of 100 women who do not use any birth control will get pregnant over one year.
There are also risks that happen when the birth control method is not used correctly. Each birth control method has its own risks. Birth control methods are different in how well they work.
