We have more birth control options than ever before (thanks, science!)—an awesome thing when it comes to preventing unwanted pregnancy and sexually transmitted infections (STIs). Given the stakes, it’s something everyone could use a primer on.

But with so many effective options readily available, where do you start? We’ll get into what each method does and how to use it; but first, a word on effectiveness.

Perfect use vs. typical use

Most of the stats you see on how well a birth control method works refer to “perfect use” or “theoretical use.” That means that in clinical trials with lab-controlled participants, that’s how effective the birth control method would be at preventing pregnancy.

But that’s not necessarily how it works in real life, says Dr. Colleen Krajewski, or Dr. K., Assistant Professor at the University of Pittsburgh in Pennsylvania and Medical Advisor to Bedsider.org, an online birth control support network operated by the National Campaign to Prevent Teen and Unplanned Pregnancy. “There’s no [sense in] discussing perfect use in clinical practice,” she says. “Typical use” stats are the ones to pay attention to—these are how effective experts estimate a given birth control method is IRL.

Part of a birth control method’s effectiveness is in your control. For example, learning the proper way to use a condom—and then making sure to follow the right steps every single time.

But sometimes it’s out of your control. “There are a lot of reasons that birth control methods can fail,” says Dr. K. Learn what can impact the pill’s effectiveness.

The bottom line? Pay attention to stats about actual effectiveness and make sure to take the proper precautions accordingly.

male condoms

Made of multiple materials, including latex or polyurethane, condoms cover the penis to block sperm from entering the vagina or anus and help prevent the spread of STIs through skin-to-skin contact.

Condoms are 82 percent effective at preventing pregnancy with typical use. They’re also effective for preventing STIs.

Almost anywhere. At the drugstore, health clinics, your student health centre, even online.

Because it protects against STIs as well as pregnancy, “you can pretty much add a condom to anything—except another condom,” says Dr. K, as the increased friction can increase the risk of tears. Note: If you opt for lambskin condoms due to a latex allergy, keep in mind that they aren’t as effective at preventing STIs.

“Use a condom each time. Make sure they’re easily accessible, stored appropriately, and not past their expiration date.” —First-year graduate student, Queen’s University, Ontario

Female condoms

The inverse of male condoms—rather than blocking sperm and STIs by covering the outside of the penis, female condoms are inserted into the vagina.

Female condoms are about 79 percent effective with typical use.

These are a lot harder to find in stores than the male versions. Check drugstores, online sites, or your nearest sexual health clinic.

Female condoms can be used just like male condoms. If you’re a heterosexual woman, they can offer more autonomy—in other words, you won’t have to rely on the guy to pack protection and be using protection properly.

Sponge

Shaped like a spongy little button with a string attached, the sponge physically blocks the cervix and also kills sperm. You can have sex multiple times while it’s in (up to 30 hours), unlike condoms, which have to be new every time.

76–88 percent effective with typical use.

While not as common as condoms, you can find birth control sponges in some drugstores or online.

Like the female condom, the sponge gives women more autonomy over their birth control. However, it doesn’t protect against STIs and isn’t the most effective for preventing pregnancy.

The pill

The birth control pill prevents pregnancy by adding a daily dose of hormones into your system that prevent the ovaries from releasing eggs.

91 percent effective at preventing pregnancy with typical use. It doesn’t protect against STIs.

Typically, the pill is prescribed by your health care provider. You can also get prescriptions from a local sexual health clinic. If cost is a barrier, explore low-cost prescription options and pharmacy savings clubs via large retailers such as Walmart or Costco. You can also try getting them online via telehealth services like Pandia Health or PRJKT RUBY.

Because it works by impacting your body’s hormone cycles, the pill needs to be taken at the same time every day for it to work. Oral contraceptive pills may provide other benefits, such as improving acne or easing painful periods.

“I keep my pills by my toothbrush—so I pair taking the pill with a lifelong habit and take it at approximately the same time every day. If I do forget to take a pill, I always use a condom as a secondary mode of protection against pregnancy.” —Third-year graduate student, University of Victoria, British Columbia

Emergency contraception pill

The emergency contraception (EC) pill, aka the “morning-after” pill, is like a super-concentrated version of the pill that blocks a pregnancy before it can start. “It’s an over-the-counter medication that’s very safe—it’s not a bad idea to keep it in your medicine cabinet just in case,” says Dr. K.

Visit SexandU for more info

95 percent effective 3­­–5 days after sex with typical use. It doesn’t protect against STIs.

Get it at your student health centre, local drugstore or health clinic, or online without a prescription.

When a condom breaks or other birth control method fails. Remember, it doesn’t protect against STIs.

Intrauterine Device (IUD)

The IUD is a tiny T-shaped device inserted into the uterus by a health care provider. It prevents pregnancy by disabling sperms’ ability to swim. There are two main types of IUDs: copper (no hormones) and progesterone (a hormone that keeps your ovaries from releasing eggs, like the pill, and helps block sperm from getting into the uterus). With the latter, you may experience lighter or even no periods.

99 percent effective against pregnancy with typical use. The IUD doesn’t protect against STIs.

You need a health care provider to get an IUD. If you don’t have a regular gynecological care provider (or aren’t comfortable going to them), check your local health clinics.

Since the IUD doesn’t pump hormones into your body (progesterone stays in the uterus), it’s a good option if you’ve experienced bad side effects from the pill. “This is a set-and-forget method. You put it in place, and it’ll be effective for 3–10 years, depending on the type,” says Dr. Wendy Norman, Assistant Professor at the University of British Columbia.

“I have a hormonal IUD. I’ve had it replaced once at a sexual health clinic and intend to have my current one replaced in a few years.” —Fourth-year undergraduate, University of Victoria, British Columbia

The ring

The ring is a flexible little circle you insert into your vagina—sort of like slipping in a tampon—which gives off hormones that prevent the ovaries from releasing eggs and thickens cervical mucus to help prevent sperm from entering the uterus.

91 percent effective with typical use. It also doesn’t protect against STIs.

You need a prescription. Talk to your provider.

The ring is a great middle ground between the IUD and the pill.

Depo-Provera (the shot)

Like the pill and the ring, the shot prevents pregnancy via progesterone, which keeps your ovaries from releasing eggs. Once you get the shot, you’re protected for three months.

Visit SexandU for more info

94 percent effective with typical use. The shot doesn’t prevent STIs.

After an initial exam, a health care provider can administer the shot. Ask your provider or see your local health clinic.

If you struggle to remember to take your birth control, or don’t want to have to think about your birth control every day, the shot is a great alternative. One caveat: It does have potential side effects associated with weight gain. “If you’re someone who struggles with your weight and with your appetite, the shot is probably not for you,” says Dr. K.

"Not right now" or abstinence

You don’t engage in any type of sexual activity 100 percent of the time.

There’s only one way that’s 100 percent effective at preventing both pregnancy and STIs—when practiced 100 percent of the time, abstinence is 100 percent effective.

If anything other than having a zero percent chance of an unwanted pregnancy or STI worries you, it’s an option to consider. At the end of the day, do what’s right for you.

1. Identify your priorities

  • Each method has pluses and minuses.
  • There isn’t one best method in the world for everyone.
  • Preventing pregnancy and STIs should be an ongoing discussion with your partner and health care provider. Know what your priorities are and what you’d be willing to compromise on. For example:
    • Is pregnancy prevention your number-one priority?
    • Do you care about regulating your period?

2. Be ready, whatever your relationship status

  • Even if you’re not in a long-term relationship, it can still make sense to think about long-term birth control.
  • Being protected and safe, and taking control of your body, is empowering.
  • The IUD is a great long-term birth control option for many people.
  • Keeping emergency contraception on hand at all times can save you a whole lot of stress and inconvenience later.

3. Make conversation, not assumptions

  • Conversations with your partner, not assumptions, are key to healthy sexual and nonsexual relationships.
  • For example, if your partner observes a particular religion, you still need to talk about birth control, sexuality, boundaries, and other topics. Everyone is different.

4. Make sure you get the facts

  • There’s a lot of misleading info out there so make sure you’re only getting your info from reliable sources.
  • Great websites with reliable info include SexandU.ca and Bedsider.org.
