Birth control methods work in different ways, cost different amounts, and fit different lives

Birth control prevents pregnancy by stopping sperm from reaching an egg, stopping ovulation, or preventing a fertilized egg from implanting. The main categories are barrier methods (condoms, diaphragms), hormonal methods (pills, patches, shots, implants), copper devices, and permanent options (tubal ligation, vasectomy). Each method has a different failure rate in real-world use, a different cost, a different schedule of visits or refills, and different side effects. The right choice depends on how often you have sex, whether you want to prevent sexually transmitted infections, what your body tolerates, how much you want to think about it, and what you can afford or what your insurance covers.

Key Takeaways

  • Barrier methods like condoms are the only birth control that also prevents sexually transmitted infections, but they have higher failure rates than hormonal or device methods when used alone.
  • Hormonal birth control (pills, patches, shots, implants) prevents ovulation and requires either daily use or a visit every few months to a year, depending on the method.
  • Copper IUDs and hormonal IUDs work for three to twelve years without any action on your part, but insertion and removal require a clinic visit.
  • Permanent methods like tubal ligation and vasectomy are over 99 percent effective but are difficult or impossible to reverse, so they suit people certain they do not want children.
  • Cost varies widely: some methods are free or low-cost under insurance, while others cost $30 to $1,000 out of pocket depending on your coverage and the provider.

Barrier methods: condoms, diaphragms, and cervical caps

Barrier methods physically block sperm from reaching the egg. Condoms are the most common and the only method that also prevents sexually transmitted infections. Male condoms cover the penis; female condoms line the vagina. Both are available without a prescription at drugstores, cost $0.50 to $2 per condom, and work when ready. The catch is that they must be used every single time, and real-world failure rates are around 18 percent per year because people forget, use them incorrectly, or do not use them at all.

Diaphragms and cervical caps are dome-shaped devices that cover the cervix and must be fitted by a doctor or nurse practitioner. They require a prescription, cost $15 to $75 for the device itself, and must be used with spermicide (a chemical that kills sperm). They do not prevent infections. Real-world failure rates are similar to condoms—around 12 percent per year for diaphragms—because they must be inserted before sex and left in place for six hours afterward. Many people find them inconvenient compared to other options.

Hormonal birth control: pills, patches, shots, and implants

Hormonal methods use synthetic versions of estrogen and progestin (or progestin alone) to stop the ovaries from releasing an egg. The most common is the birth control pill, taken by mouth once a day. Pills cost $0 to $50 per month depending on insurance and the specific brand; many insurance plans and Medicaid cover them at no cost. They work well if taken consistently, but real-world failure rates are around 9 percent per year because people miss doses or take them at the wrong time.

The patch, ring, and shot are alternatives that require less frequent action. The patch sticks to skin and is changed weekly; the ring sits in the vagina and is changed monthly; the shot is injected every three months. All prevent ovulation the same way pills do. Patches and rings cost $0 to $50 per month; shots cost $0 to $60 per injection depending on insurance. The implant is a small plastic rod inserted under the skin of the upper arm by a doctor and releases progestin for three years. It costs $0 to $1,300 out of pocket but is often free or low-cost under insurance. Implants have a real-world failure rate under 1 percent because there is nothing for you to remember or do.

Hormonal methods can cause side effects including nausea, headaches, breast tenderness, mood changes, and changes in sex drive. These often improve after two or three months. Some people have no side effects; others find them intolerable. The only way to know is to try one and track how you feel for at least three months before deciding it does not work for you.

Intrauterine devices: copper and hormonal IUDs

An IUD is a small T-shaped device inserted into the uterus by a doctor or nurse practitioner. Copper IUDs (like Paragard) release copper, which is toxic to sperm. Hormonal IUDs (like Mirena, Kyleena, and Skyla) release a small amount of progestin directly into the uterus. Both prevent pregnancy without any action on your part after insertion. Real-world failure rates are under 1 percent.

Copper IUDs work for ten to twelve years; hormonal IUDs work for three to seven years depending on the brand. Insertion takes about five minutes but can be uncomfortable or painful, especially for people who have never been pregnant. Removal is quick and reversibility is when ready—you can become pregnant as soon as the device is out. Cost ranges from $0 to $1,300 out of pocket, but most insurance plans and Medicaid cover IUDs at no cost. If you pay out of pocket, the cost is high upfront but spreads to pennies per month over years of use.

Copper IUDs often cause heavier, longer, or more painful periods, especially in the first few months. Hormonal IUDs usually make periods lighter or stop them entirely. Some people experience cramping, spotting, or mood changes. These side effects often improve after three to six months.

Permanent methods: tubal ligation and vasectomy

Tubal ligation is surgery that blocks or removes the fallopian tubes so eggs cannot reach the uterus. Vasectomy is a simpler procedure that blocks the vas deferens so sperm cannot leave the testicles. Both are over 99 percent effective and are permanent—reversal is possible but expensive, difficult, and not always successful. These methods suit people who are certain they do not want children or do not want more children.

Tubal ligation is done under general anesthesia in an operating room or outpatient surgery center and costs $0 to $6,000 out of pocket depending on insurance and the method used (open surgery, laparoscopy, or hysteroscopy). Recovery takes one to two weeks. Vasectomy is done in an office under local anesthesia and costs $0 to $1,500 out of pocket. Recovery takes a few days, and the procedure is not when ready effective—semen must be tested to confirm no sperm are present, which takes eight to sixteen weeks.

How to think about cost, side effects, and what fits your life

The "best" birth control is the one you will actually use and that your body tolerates. Start by asking yourself: How often do you have sex? Do you need protection against infections? How much do you want to think about birth control—daily, monthly, yearly, or never? What side effects can you live with? What does your insurance cover?

If you have sex rarely or unpredictably, condoms or a diaphragm may make sense because you do not pay for something you are not using. If you have regular sex and want to forget about birth control, an IUD or implant is worth the upfront cost and insertion visit. If you want a method you control completely, a pill or patch gives you that. If you are certain you do not want children, permanent methods eliminate the need to choose again.

Cost matters, and it varies. Many insurance plans cover all FDA-approved birth control methods at no cost under the Affordable Care Act. Medicaid covers them in most states. If you do not have insurance or your plan does not cover your preferred method, Planned Parenthood, community health centers, and some local health departments offer birth control on a sliding fee scale based on income. Some manufacturers offer copay cards that reduce your out-of-pocket cost to $0 to $35 per month.

Where to get birth control and what to expect

You can get condoms at any drugstore without seeing anyone. For all other methods, you need to see a doctor, nurse practitioner, or physician assistant. Your primary care doctor can prescribe pills, patches, shots, and rings. Gynecologists, family medicine doctors, and nurse practitioners at community health centers can insert IUDs and implants and perform permanent procedures. Planned Parenthood offers all methods at locations across the country.

At your first visit, expect questions about your medical history, current medications, and whether you smoke (smoking with hormonal birth control raises the risk of blood clots). You may have a blood pressure check and possibly a pelvic exam, depending on the method. The visit usually takes thirty minutes to an hour. If you choose an IUD or implant, insertion happens the same day or at a follow-up appointment. If you choose a pill, patch, shot, or ring, you can start when ready or wait until your next period, depending on when you want protection to begin.

Frequently Asked Questions

Can I use birth control while breastfeeding?

Yes, but not all methods. Hormonal methods containing estrogen can reduce milk supply, so progestin-only options like the mini-pill, implant, hormonal IUD, or shot are preferred. Copper IUDs and barrier methods are safe. Talk to your doctor about timing—some methods work better if you wait a few weeks after birth.

What if I forget to take my birth control pill?

If you miss one pill, take it as soon as you remember, even if that means taking two pills in one day. If you miss two or more pills, use a backup method like condoms for seven days and continue taking one pill daily. Missing pills increases your risk of pregnancy, so consider a method that requires less frequent action.

Do I need a pap smear to get birth control?

No. A pap smear screens for cervical cancer and is separate from birth control. You may have a blood pressure check or health history review, but a pap smear is not required to start most birth control methods. Your doctor will tell you if one is needed based on your age and history.

Can birth control cause blood clots or stroke?

Hormonal birth control containing estrogen slightly raises the risk of blood clots and stroke, especially in people who smoke, are over 35, have high blood pressure, or have a personal or family history of clots. Progestin-only methods (mini-pill, implant, hormonal IUD, shot) do not carry this risk. Discuss your personal risk factors with your doctor.

What happens if I want to switch methods?

You can switch at any time. If you are moving from one hormonal method to another, you can start the new one when ready. If you are removing an IUD or implant, you can insert a new one the same day or start a different method right away. Your doctor can advise on timing to avoid gaps in protection.
