Smart and Safe Birth Control Options

A smart birth control plan factors in your age, health, life stage, relationship status and personality—and evolves over time.

As your body and life circumstances change, so may your birth control needs.

The most important thing to remember about birth control is to use it—and use it properly—every time you have sex. While even the most effective methods can fail, your chances of getting pregnant are lower when you use birth control correctly every time you have sex. Almost 50 percent of all pregnancies in the U.S. are unintended. Unintended or closely spaced pregnancies are linked to negative health consequences for mother and child. Plus, research suggests that unintended pregnancy can negatively affect a woman's physical, emotional and economic well-being.

Many birth control methods do more for you than just prevent pregnancy. For instance, the pill and other hormonal methods may reduce the risk for developing certain cancers and improve menopausal and premenstrual syndrome (PMS) symptoms, such as heavy bleeding and mood swings.

Keep in mind that, with the exception of latex male condoms and female condoms, birth control will not protect you against sexually transmitted infections (STIs), like chlamydia, gonorrhea and human immunodeficiency virus (HIV).

Birth Control Options

Note that for birth control to work, you must use it correctly. With perfect use, hormonal birth control, such as the birth control pill, patch or implant, hormonal intrauterine device (IUD) or vaginal ring, are about 99% effective. But with typical use, these methods are closer to 90% effective. If you don't take your pill on time or receive the shot as often as directed, for instance, this can increase your chances of unintended pregnancy. Here's an overview of different birth control methods in order of effectiveness:

Type Abstinence
How It Works Abstinence is refraining from any sexual activity that could result in pregnancy.
Effectiveness
  • 100% effective.
  • Note that pregnancy is still possible if semen touches the vulva and gets into the vagina
Considerations
  • Not recommended for people who find it difficult to abstain from intercourse.
  • It can be beneficial to have a backup method of birth control available, such as condoms.
Type Surgery/ Permanent Birth Control
How It Works

Tubal ligation:
A woman can have her fallopian tubes tied as a means of permanent birth control. In this surgery, a doctor cuts, ties or seals the fallopian tubes to block eggs from reaching the uterus.

Vasectomy:
This surgery is done to keep a man's sperm from entering his penis, so when he ejaculates there is no sperm to fertilize the egg. It involves closing or blocking the tubes in men that carry sperm.

Effectiveness
  • Nearly 100% effective for both men and women.
  • After a vasectomy, it takes about 12 weeks before sperm are completely cleared from a man's ejaculate. The man will visit his doctor after the procedure for tests to check sperm count. Use a backup form of birth control until the sperm count reaches zero.
Considerations
  • Not recommended for people who may want to have biological children in the future. Surgery can be difficult to reverse.
Type IUD
How It Works

There are two types of IUDs:

Copper IUDs:
A small, plastic device containing copper is inserted into the uterus by a health care provider. Copper acts as a natural spermicide, disrupting the sperm's path to the egg.

Hormonal IUDs:
Hormonal IUDs, which are also inserted into the uterus by a health care provider, release the hormone progestin, which disrupts the sperm's path to the egg, helps to thicken cervical mucus, and may also prevent the egg from leaving the ovary.

Effectiveness
  • 99% effective with perfect use
  • 90% effective with typical use
Considerations
  • The copper IUD may work for up to 10 years. The hormonal IUD may be effective for 3–5 years.
  • Recommended for women who know they do not want to become pregnant for several years.
Type Birth Control Implant
How It Works A small rod implanted by a health care provider in a woman's arm releases the hormone progestin, which can suppress ovulation and thicken cervical mucus to block sperm.
Effectiveness
  • 99% effective with perfect use
  • 90% effective with typical use
Considerations
  • Surgery is required to insert the rod. Once it's in place for a week, it can be effective for up to five years.
Type Birth Control Shot or Injection
How It Works A hormonal injection of progestin that prevents pregnancy by stopping eggs from leaving the uterus and by thickening the cervical mucus to block sperm. The shot is typically given in the upper arm and lasts for 12 weeks.
Effectiveness
  • 99% effective with perfect use
  • 90% effective with typical use
Considerations
  • Can be a good option for women who don't want to take a daily pill.
  • The chance of pregnancy is lower in women who receive the shot on time every 12 weeks.
Type Birth Control Patch
How It Works A skin patch worn on the buttocks, lower abdomen, upper, outer arm or upper body for 3 consecutive weeks at a time. The patch releases progestin and estrogen to prevent ovulation and thickens cervical mucus to block sperm from reaching the egg.
Effectiveness
  • 99% effective with perfect use
  • 90% effective with typical use
Considerations
  • Can be used by women who are eligible for hormonal birth control but do not want to take a daily pill.
  • Not recommended for women with certain health conditions (such as a history of heart problems, high blood pressure, blood clots, certain cancers, and more) or women over the age of 35 years who smoke.
Type Birth Control Pills/ Oral Contraception
How It Works A daily hormonal pill to prevent pregnancy. The combination pill contains progestin and estrogen to suppress ovulation. The progestin-only “mini pill” helps to prevent pregnancy by thickening cervical mucus to block sperm.
Effectiveness
  • 99% effective with perfect use
  • 90% effective with typical use
Considerations
  • May be recommended for women who want benefits not related to birth control, such as more regular and lighter periods and reduced menstrual cramps.
  • Progestin-only pills may be recommended for breastfeeding women, or those who are unable or choose not to take estrogen.
  • Combination pills should not be taken by women over 35 years who smoke or those with certain health conditions, such as heart problems, high blood pressure, a history of blood clots or certain cancers.
Type Birth Control Ring/Vaginal Ring
How It Works A small, flexible, plastic ring is inserted into the vagina once a month, releasing estrogen and progestin to suppress ovulation and thicken cervical mucus to block sperm.
Effectiveness
  • 99% effective with perfect use
  • 90% effective with typical use
Considerations
  • You'll leave the ring in place for three weeks, remove it and then insert a new ring exactly one week later. The ring is most effective when you follow these directions exactly.
Type Exclusive Breastfeeding/ Lactational Amenorrhea
How It Works

Breastfeeding can be a short-term effective form of birth control when all three of these considerations are met:

  • The baby you're breastfeeding is younger than 6 months old.
  • You exclusively breastfeed your baby. This means you only give them breast milk and no formula or solid foods.
  • You have not had a menstrual period since giving birth.
Effectiveness
  • 98% effective with perfect use
  • Is not effective if all three criteria aren't met
Considerations
  • Only an effective option for new moms who breastfeed exclusively.
  • New moms who breastfeed but sometimes supplement with formula may have a higher risk of ovulating, and a higher chance of becoming pregnant.
Type Diaphragm or Cervical Cap with Spermicide
How It Works These devices prevent pregnancy by blocking the cervix and are used with spermicide—a chemical that stops sperm from moving so it can't reach the egg. The cap is a thimble-shaped cup, and the diaphragm is a shallow cup. Before having sex, place about 1 teaspoon of spermicide into the cap or diaphragm (you can also put spermicide directly into the vagina), then you insert the cap or diaphragm into the vagina and over the cervix. If you have sex more than once, apply more spermicide. Remove it at least six hours later.
Effectiveness
  • Diaphragm:
    • 94% effective with perfect use
    • 88% effective with typical use
  • Cervical cap:
    • 84–87% effective with typical use in women who have never been pregnant or given birth vaginally
    • 68–77% effective with typical use in women who have given birth vaginally
Considerations
  • Both methods are only effective when used with spermicide.
  • Cervical caps and diaphragms are available in different sizes. Your health care provider can help determine the size you need.
Type Birth Control Sponge with Spermicide
How It Works The sponge covers the cervix so that sperm cannot reach any eggs in the uterus, and releases a spermicide. Before sex, insert the sponge deep inside the vagina so it covers the cervix.
Effectiveness

In women who have never given birth:

  • 91% effective with perfect use
  • 88% effective with typical use

In women who have given birth:

  • 80% effective
  • 76% effective with typical use in women who have given birth
Considerations
  • Not recommended for women who have recently given birth or been pregnant
Type Male Condom and Female Condom
How It Works The male condom is a thin cover that is placed onto an erect penis and worn during sex. The female condom is a lubricated plastic tube with a ring at each end to help it stay in place inside the vagina during sex. Both types of condoms block sperm from entering the vagina.
Effectiveness
  • Male condom:
    • 98% effective with perfect use
    • 87% effective with typical use
  • Female condom:
    • 95% effective with perfect use
    • 79% effective with typical use
Considerations
  • Consistently and correctly using male latex condoms can protect both men and women against STIs.
  • Male condoms made from materials other than latex, such as polyurethane, polyisoprene or lambskin, do not protect against STIs or HIV.
  • There are only a few studies that show female condoms may help protect against STIs, but more research is needed for this to be confirmed. It is unknown if female condoms protect against HIV.
Type Withdrawal
How It Works A man withdraws his penis from the vagina (or "pulls out") before ejaculation to stop sperm from entering.
Effectiveness
  • Only works if semen (including pre-ejaculate fluid or sperm remaining in the urethra from previous ejaculation) stays out of the vagina.
  • 96% effective with perfect use
  • 78% effective with typical use
Considerations
  • Sperm can be released before the man pulls out, so it's often not an effective form of birth control.
Type Fertility Awareness Methods (FAM)/ Natural Family Planning
How It Works Fertility awareness methods require charting or tracking cycles and avoiding unprotected sex during peak fertile times.
Effectiveness
  • Several different types of FAM exist; effectiveness varies between each type.
  • FAM is less effective than many other methods of birth control.
Considerations
  • Not recommended for women with irregular menstrual cycles.
  • These methods can be useful for couples who are trying to get pregnant. In these cases, they have unprotected sex during peak fertile times.

 

 

Emergency Birth Control

Emergency contraception is not a regular form of birth control, but it can be an option to prevent pregnancy after you've had unprotected sex. If used within five days of unprotected sex, emergency contraceptive pills (morning after pills) or the emergency insertion of a copper-T IUD can significantly reduce the risk of pregnancy by preventing fertilization. The copper-T IUD reduces the risk of pregnancy by 99%, and the sooner you take the pills after having unprotected sex, the better they work.

Have a Backup Plan

Even the most effective birth control methods can fail. To make sure you are truly covered (and to enjoy peace of mind), consider using a backup birth control method in addition to your regular one. You can combine one or more methods, such as using condoms in conjunction with the pill, to reduce the risk of unintended pregnancy. Make sure to read labels and instructions carefully, and be especially aware of any situation (like missing a pill) that would require the use of a second birth control method.

Work with Your Health Care Provider

Before you try a new method of birth control, be sure to understand how to use it properly, as well as what it does—and doesn't—protect against. Discuss the risks, benefits, potential side effects and possible drug interactions with your health care provider to ensure your birth control method is a good match for you. For example, women with certain health conditions shouldn't use some forms of hormonal birth control due to increased side effects. In addition, taking certain medications or being pregnant recently can make some types of birth control less effective. Your health care provider can make birth control recommendations based on your needs and preferences.
