Birth control methods compared

How to compare them

Every method has two success rates. Perfect use is how well it works when used exactly right every time. Typical use is how well it works in real life, with missed pills and mistakes. is the one to compare.1

A bar chart of pregnancies per 100 people in the first year with typical use. Implant 0.1, hormonal IUD 0.1 to 0.4, vasectomy 0.15, tubal surgery 0.5, copper IUD 0.8, shot 4, pill, patch or ring 7, external condom 13, diaphragm 17, sponge 17, fertility awareness 2 to 23, internal condom 21, spermicide 21, cervical cap 22.

The methods at the top work best because, once they're in place, there is nothing to remember.

The methods

Long-acting, reversible1

  • Implant. A thin rod under the skin of the upper arm that releases a for up to 3 years.
  • Hormonal IUD. Placed in the uterus by a clinician. Releases a progestin and lasts 3 to 8 years, depending on the device.
  • Copper IUD. No hormones. Lasts up to 10 years. It can make periods heavier, especially in the first year.2

Short-acting, hormonal1

  • Shot. A progestin injection every 3 months.
  • Pill. Taken at the same time every day. Combined pills have estrogen and progestin; progestin-only pills have just progestin.
  • Patch. A new one each week for 3 weeks, then a week off.
  • Ring. Worn in the vagina for 3 weeks, then a week off.

Barrier and other methods1

  • Condoms. External condoms go on the penis; internal condoms go in the vagina. Latex condoms also help prevent HIV and other STIs. "Natural" lambskin condoms may not.
  • Diaphragm, cervical cap and sponge. Placed in the vagina before sex, used with spermicide.
  • Fertility awareness. Tracking the cycle to avoid sex, or use a barrier, on fertile days.

Permanent1

  • Tubal surgery closes or cuts the fallopian tubes. Vasectomy blocks sperm in men; another method is needed for about 12 weeks until a test confirms it worked.

Most methods don't protect against STIs, so condoms are needed for that, alongside any other method.1

More than birth control

Hormonal methods can also treat period problems. Combined methods can make periods lighter and more regular, and the hormonal and the shot may stop bleeding altogether after a year.3 Hormonal methods are also used for painful periods.4

Myth: Birth control ruins your fertility.

It's a very common worry, and an understandable one. A review of 22 studies with nearly 15,000 women found that 83% got pregnant within a year of stopping. The rate was the same for hormonal methods and IUDs, and it didn't matter how long the pill had been used.5

Myth: You need a monthly bleed on the pill to stay healthy.

Many of us assumed the bleed was necessary. The bleed on the pill, patch or ring is a withdrawal bleed, not a true period, and it only happens because the method was designed to mimic a natural cycle. There's no medical reason to have one, and skipping it is usually safe. Talk to your doctor before you start.6

Choosing

There is no single best method. It depends on what matters to you: how effective it is, whether you'd rather not think about it, hormones or no hormones, effects on bleeding, cost and privacy. A doctor, nurse or family planning clinic can help you weigh them.

Recap

  • The implant, IUDs and sterilization fail for less than 1 in 100 people a year.
  • The shot, pill, patch and ring fail for 4 to 7 in 100 people a year with typical use, mostly because of missed doses.
  • Condoms are the only method that also helps prevent STIs.
  • Birth control doesn't harm future fertility. Most people get pregnant within a year of stopping.
  • Skipping the bleed on the pill, patch or ring is usually safe. Ask a doctor first.
