If you do not want to get pregnant, there are many birth control options to choose from. No one product is best for everyone. The only sure way to avoid pregnancy and sexually transmitted infections (STIs or STDs) is not to have any sexual contact (abstinence). This page lists FDA-approved methods for birth control. Talk to your doctor, nurse, or pharmacist about the best method for you.
There are different kinds of medicines and devices for birth control:
Permanent Sterilization
Long-Acting Reversible Contraceptives (LARC)
Short-Acting Hormonal Methods
Barrier Methods
Emergency Contraception
Some things to think about when you choose birth control:
Your health.
How often you have sex.
How many sexual partners you have.
If you want to have children in the future.
If you will need a prescription or if you can buy the method over-the-counter.
The number of pregnancies expected per 100 women who use a method for one year. For comparison, about 85 out of 100 sexually active women who do not use any birth control can expect to become pregnant in a year.
This page lists pregnancy rates based on typical use. Typical use shows how effective the different methods are during actual use (including sometimes using a method in a way that is not correct or not consistent).
For more information on the chance of getting pregnant while using a method, please see Trussell,J. (2011)."Contraceptive failure in the United States." Contraception 83(5):397-404. disclaimer icon
Tell your doctor, healthcare provider, or pharmacist if you:
Smoke.
Have liver disease.
Have blood clots.
Have family members who have had blood clots.
Are taking any other medicines, like antibiotics or daily prescription medicines.
Are taking any herbal products, like St. John’s Wort.
Are breastfeeding.
Have been pregnant recently.
To avoid pregnancy:
No matter which method you choose, it is important to follow all of the directions carefully. If you don’t, you increase your chance of getting pregnant.
The best way to avoid pregnancy and sexually transmitted infections (STIs) is to practice total abstinence (do not have any sexual contact).
Sterilization Implant for Women (Transcervical Tubal Sterilization Implant)
Transcervical Surgical Sterilization Implant
What is it?
Small flexible, metal (containing nickel) coil that is put into the fallopian tubes with a special catheter through the vagina.
How does it work?
The device works by causing scar tissue to form around the coil. This blocks the fallopian tubes and stops you from getting pregnant.
You need to use another birth control method during the first 3 months. You will need a special test to make sure the device is in the right place before you can stop your birth control.
It is permanent.
How do I get it?
The devices are placed into the tubes using a camera placed in the uterus.
You will probably need anesthesia.
Because it is inserted through the vagina, you do not need an incision (cutting).
Chance of getting pregnant with typical use (Number of pregnancies expected per 100 women who use this method for one year)
Out of 100 women who use this method, less than 1 may get pregnant.
Some Risks
Pain
Ectopic (tubal) pregnancy
Improper device location (may need surgery to remove)
Does it protect me from sexually transmitted infections (STIs)? No.
Sterilization Surgery for Women (also called trans-abdominal surgical sterilization)
Surgical sterilization implant
What is it?
One way is by tying and cutting the tubes — this is called tubal ligation.
The fallopian tubes also can be sealed using an instrument with an electrical current.
They also can be closed with clips, clamps, or rings.
Sometimes, a small piece of the tube is removed.
How does it work?
The fallopian tubes are blocked so the egg and sperm can’t meet in the fallopian tube. This stops you from getting pregnant.
It is permanent.
How do I get it?
This is surgery.
You will need general anesthesia.
Chance of getting pregnant with typical use (Number of pregnancies expected per 100 women who use this method for one year)

Ectopic (tubal) pregnancy

Sterilization Surgery for Men (Vasectomy)
This method is for men who are sure they never want to have a child or do not want any more children. If you are thinking about reversal, vasectomy may not be right for you. Sometimes it is possible to reverse the operation, but the likelihood of reversal decreases the more time passes between vasectomy and reversal. Reversal involves complicated surgery that might not work.
Vasectomy
What is it?
This is a surgery a man needs only once.
It is permanent
How does it work?
The surgery blocks a man’s vas deferens (the tubes that carry sperm from the testes).
After this surgery, the semen (the fluid that comes out of a man’s penis) has no sperm in it.
It takes about three months to clear sperm out of a man’s system. You need to use another form of birth control until a test shows there are no longer any sperm in the seminal fluid.
How do I get it?
This is surgery.
Local anesthesia is used.
Chance of getting pregnant with typical use (Number of pregnancies expected per 100 women who use this method for one year)
Out of 100 women whose partner has had a vasectomy, less than 1 may get pregnant.
Some Risks
Pain
Bleeding
Infection
The success of reversal surgery depends on:
The length of time since the vasectomy was performed.
Whether or not antibodies to sperm have developed.
The method used for vasectomy
Length and location of the segments of vas deferens that were removed or blocked.
Does it protect me from sexually transmitted infections (STIs)? No.
Long-acting Reversible Contraceptives (LARC)- These methods are highly effective in preventing pregnancy, last for several years, and are easy to use. If you want to get pregnant, you can stop using them at any time.

What is it?

How does it work?
The IUD prevents sperm from reaching the egg, from fertilizing the egg, and may prevent the egg from attaching (implanting) in the womb (uterus).

The copper IUD can be used for up to 10 years.

How do I get it?
A doctor or other healthcare provider needs to put in the IUD.

IUD with progestin
What is it?
A T-shaped device containing a progestin that is put into the uterus by a healthcare provider.
