Long term methods include three types of pregnancy prevention methods that work for several years. One type of long term method is known as sterilization. It is considered a permanent method because the chances of reversing it so that someone can get pregnant is very small. Sterilization methods are used by people who do not want any children, or who have had all the children they want and do not want any more.
The second kind is called an interuterine device or system. This type of method can be used for three years or more depending on the type chosen. The third kind is the implant; this method can be used for three years.
Long term methods work very well to prevent pregnancy, but do not protect against HIV or other sexually transmitted diseases. If you are having sex with someone who might give you a sexually transmitted disease, use a condom.
The implant is a very small plastic device that is made with progestin. It works like contraceptive pills to prevent pregnancy. The implant is inserted in the inner part of the upper arm, where it can stay in place for up to 3 years.
Perfect user: A person who uses their method of pregnancy prevention correctly all of the time.
With perfect use, the implant is 99%+ effective.
This mean that if 100 women use the implant, it is inserted correctly by the clinician, and it is working perfectly for her, only 1 woman (probably no women) out of that group will get pregnant in 1 year.
Important: Some women have the implant removed when they have any of these side effects. The side effects won't hurt you or stop you from having a baby in the future. They usually go away in 1 to 3 months. If they bother you or don't go away, go back to your clinician so that you can talk about other methods of pregnancy prevention.
Some signs of possible serious side effects are:
Having any of these warning signs of a serious health problem from using the implant is very unusual. However, if you should have one or more of them, go to your clinician or an emergency room right away.

An IUD (intrauterine device) is a very small device made out of a type of plastic and is shaped like a "T." The main way that it works is by changing the lining of the uterus so that sperm can't live and travel well to get to the egg. A clinician places it inside a woman's uterus to prevent pregnancy. It stays there and works for 5 to 10 years, depending on which kind of IUD is used.
Two small strings are attached to the IUD. These strings hang down through the cervix (the opening of the uterus). The strings help the woman know that her IUD is in place. They also help the clinician take the IUD out when the time comes.
The strings can't be felt by the woman when she goes about her normal day. It also can't be felt by her or her partner during intercourse. A clinician can remove the IUD whenever the woman decides she no longer wants to use it as her method of pregnancy prevention or has decided to become pregnant.
There are two types of IUDs being used in the United States:
The IUD does not protect against HIV and STDs. If you have sex with someone you think could give you an STD, be sure to use a condom.
Paragard is at least 99.2% effective.
That means that if 100 women use Paragard, only 1 woman (and probably no women) out of that group will get pregnant.
Mirena is 99.9% effective.
That means that if 100 women use Mirena, only 1 woman (and probably no women) out of that group will get pregnant in a year.
Both IUDs have these possible side effects:
Paragard may also have these side effects:
Mirena may have these side effects:
If you experience one or more of these warning signs, it could mean you have a pelvic infection or the IUD is out of place. Go to your clinician or to an emergency room as soon as possible.
IUDs work very well to prevent pregnancy, but it is not a good method for women who have more than one sexual partner or who have partners who have other sexual partners. In these situations, the woman has a greater chance of getting a sexually transmitted disease. When a woman has an IUD and gets one or more of the diseases, she has a greater chance of getting a serious infection in her reproductive system.
Sterilization procedures are considered permanent and are chosen by people who do not want any children or any more children. The name for the sterilization procedure for women is tubal sterilization. The name for the sterilization procedure for men is vasectomy. Once a women has a tubal sterilization or a man has a vasectomy, the chances of reversing these procedures to allow the woman and man to have more children is very, very small.
Tubal sterilization is a very safe procedure that stops the egg and sperm from meeting. The fallopian tubes are the place where this happens, so if they are changed in a special way, the sperm cannot reach the egg. There are different types of tubal sterilization, such as cutting the tubes or blocking the inside of them.
Because sterilization procedures are considered permanent methods of pregnancy prevention, they are not considered good choices for teenagers. In fact, there are federal government and state government regulations that prevent physicians from performing these procedures on teenagers.
Tubal sterilization works very well to prevent pregnancy, but does not help protect against HIV and other STDs. If you are having sex with someone who might give you a sexually transmitted infection, use a condom.
Tubal sterilization is 99.5 % effective.
That means that if 100 women are sterilized, only 1 woman (and probably no women) out of that group would get pregnant in a year.
Special note: If the woman is sterilized by putting a tiny coil in her tubes, she must use another form of birth control for 3 months if she doesn't want to become pregnant.
Vasectomy is a safe and simple procedure that works very well to prevent pregnancy. It doesn't protect against HIV and other sexually transmitted diseases. If you are having sex with someone who might give you a sexually transmitted infection, use a condom.
Vasectomy is about 99.9% effective.
This means that if 100 men have vasectomies, maybe 1 of those men, and probably none of them, will get a woman pregnant in a year, especially if they follow the clinician's directions.
Special note: Men should use condoms or some other birth control method for the first 3 months and get a check-up to be sure that the surgery worked before they have sex without another method.
