Contraception – also known as birth control – is any method used to reduce the chances of unplanned pregnancy. Some forms of contraception also reduce the risk of
sexually transmitted infections (STIs). Keep reading to learn about different types of birth control and how they work. Need more info? Ask an Expert. Some forms of contraception act as a physical barrier to prevent sperm from
meeting an egg, while others use hormones to prevent pregnancy. To choose the right contraceptive for you, talk to your healthcare provider. You can see your primary care provider or visit your local health department or family planning clinic. Video Content

The different types of birth control
Contraceptives that don’t require a prescription include:
- Abstinence: This means not engaging in oral, anal or vaginal sex. With abstinence, there is no risk of pregnancy or STIs. It can be hard to maintain. Abstinence provides 100% protection against pregnancy and STIs.
- External condoms (use every time): An external condom is a barrier method that collects semen and other fluids, preventing them from entering a person’s vagina. It protects against pregnancy and STIs. They’re free at your local health department. Condoms must be used correctly every single time. Condoms break down over time, so pay attention to the expiration date. They’re 98% effective with perfect use and 85% effective with typical use. They’re available over the counter.
- Internal condoms (use every time): An internal condom is a barrier type of contraception (material much like an external condom) that is inserted into the vagina or anus before sexual intercourse. They can be inserted up to eight hours before sexual contact, help prevent pregnancy and don’t require a prescription. Internal condoms may cause skin irritation around the genitals, you must remember to use them every single time and it only protects against some STIs. With perfect use, they’re 95% effective and 79% effective with typical use.
- Withdrawal method (use every time): This is the removal of the penis before ejaculation occurs in the vagina. This method is free and more effective when using another birth control method, such as a condom. The cons are you may not be able to withdraw in time, pre-ejaculate may still contain sperm and this method doesn’t offer protection against STIs. With perfect use, it’s 96% effective and with typical use, it’s 78% effective.
- Spermicide (use every time): Spermicide comes in creams, gels, foams, films and suppositories that have chemicals to stop sperm from reaching an egg to fertilize. It doesn’t protect against STIs, must stay in place for six hours after intercourse and may cause irritation to the genitals. Spermicide is 71% effective when used alone and 97% effective when used with a condom.
Birth control methods that require a prescription include:
- Pill (take daily): This is a monthly pack of hormonal pills that must be taken once a day. It may help regulate the menstrual cycle and may be free or low-cost.

It doesn’t offer protection against STIs and may cause vaginal discomfort, headaches or breast tenderness. It’s 91% effective with typical use and 99% effective with perfect use.
- IUD (replace every three to 12 years): An intrauterine device is t-shaped and contains copper or progestin (hormone). It is inserted into the uterus by a healthcare provider.

Emergency contraception
The emergency contraception pill (sometimes called the “morning-after pill”) can reduce the chance of pregnancy after unprotected sex or if another method of birth control fails. Most options are available over the counter and don’t require a prescription. The pill must be taken within three to five days – the sooner it is taken, the more effective it is.
The copper IUD can also be used if inserted by a medical professional within five days of unprotected sex or birth control failure.
STI Prevention
The following methods are used to prevent STIs:
- Abstinence
- Condoms
- Dental dams: A thin, flexible piece of latex that is placed over the genitals or anus before oral sex. It can easily be made by an unused condom and hard to find in stores.
- PrEP, which stands for pre-exposure prophylaxis and is prescribed to people who are at risk for contracting HIV. This method only protects against HIV, not other STIs, and is best used with a barrier method. It must be taken daily.
Talk to your healthcare provider about which method is right for you.
