Overview
Contraception is the use of methods, devices, medicines, or procedures to prevent pregnancy. Common categories include condoms, birth control pills, implants, intrauterine devices (IUDs), injections, patches, vaginal rings, fertility awareness methods, and permanent procedures such as sterilization. Some methods are reversible and others are intended to be permanent. Condoms are important because they can also help reduce the spread of STIs.
Who Is Affected
Contraception may be relevant for anyone who can become pregnant or whose partner can become pregnant. People of many ages, relationship types, cultures, and health backgrounds may consider it. Needs can change over time, such as after childbirth, during breastfeeding, near menopause, or when medical conditions affect method choice.
Prevention
Contraception itself is a way to prevent unintended pregnancy. Using a method consistently and correctly improves how well it works. Dual protection means using condoms to help reduce STI risk while also using another method for pregnancy prevention. Talking with a healthcare professional can help people choose a method that fits their health needs and personal priorities.
Diagnosis and Tests
Contraception usually does not require a diagnosis because it is a preventive choice, not an illness. A healthcare professional may review medical history, menstrual history, current medicines, blood pressure, and pregnancy status before starting some methods. In some cases, screening for STIs or other reproductive health needs may also be discussed.
Treatment Categories
Contraceptive options include barrier methods such as condoms and diaphragms; hormonal methods such as pills, patches, rings, injections, and implants; and intrauterine devices, which may be hormonal or non-hormonal. Permanent contraception includes sterilization procedures for people who are sure they do not want future pregnancy. Emergency contraception may be used after unprotected sex or method failure. Not all methods are suitable for every person, especially when certain medical conditions are present.
Living With It
Choosing contraception can involve practical issues such as privacy, cost, side effects, return to fertility, and ease of use. It may help to review how comfortable you feel with a daily, monthly, long-acting, or permanent method. People sometimes change methods over time if their health, relationship, or pregnancy plans change.
Diet and Lifestyle
There is no single diet that makes contraception work better, but general health habits support overall reproductive health. Keeping a record of menstrual cycles, sexual activity, or side effects may help with method use and follow-up. If STI prevention matters, condom use remains important even when another contraceptive method is used.
When to Seek Medical Care
Seek medical care if you want help choosing a method, have trouble using your current method, think you may be pregnant, or have bothersome side effects. You should also get medical advice after unprotected sex, condom breakage, or missed contraceptive use to ask about emergency contraception and next steps. If you think you may have been exposed to an STI, arrange testing and care promptly.
When It May Be an Emergency
Get urgent medical care for severe lower abdominal pain, heavy bleeding, fainting, chest pain, trouble breathing, sudden severe headache, weakness on one side, or symptoms of a severe allergic reaction after using a contraceptive method. Urgent care is also important if you have an IUD and develop severe pain, fever, or think you might be pregnant, because pregnancy with an IUD can be serious. These symptoms need prompt evaluation.
Questions to Ask a Healthcare Professional
You may want to ask: Which methods fit my health history and pregnancy plans? How well does this method work with typical use? Does it protect against STIs? What side effects should I watch for, and when should I seek urgent care? How quickly can fertility return after stopping it?
