Birth Control Methods: Comparing Your Contraceptive Options

LARC methods are considered the gold standard of reversible contraception by ACOG and other major medical organizations. They are the most effective reversible options available, with failure rates of less than 1%, and they require no daily, weekly, or monthly action once placed.

The hormonal IUD (such as Mirena, Liletta, Kyleena, and Skyla) is a small, T-shaped device placed in the uterus by a healthcare provider. It releases a low dose of levonorgestrel (a progestin) locally in the uterus, which thickens cervical mucus, thins the uterine lining, and in some cases suppresses ovulation. Depending on the brand, hormonal IUDs are effective for three to eight years. Many women experience lighter periods, and some stop having periods altogether, which is a safe and often welcome side effect.

The copper IUD (Paragard) is a hormone-free LARC option. It works primarily by creating an inflammatory reaction in the uterus that is toxic to sperm. The copper IUD is effective for up to 10 years and is an excellent choice for women who prefer to avoid hormonal methods. However, it may cause heavier or more painful periods, particularly in the first few months after insertion.

The contraceptive implant (Nexplanon) is a small, flexible rod about the size of a matchstick that is inserted under the skin of the upper arm. It releases etonogestrel (a progestin) and is effective for up to three years. The implant is the single most effective reversible contraceptive method available, with a failure rate of less than 0.05%. Irregular bleeding is the most common side effect, particularly in the first six to twelve months.

Short-acting hormonal methods require more active participation but offer flexibility and are widely used. The combined oral contraceptive pill contains both estrogen and progestin and is taken daily. With perfect use, the pill is over 99% effective, but with typical use (accounting for missed pills and late doses), the failure rate is approximately 7-9%. The pill offers benefits beyond contraception, including more regular and lighter periods, reduced acne, and decreased risk of ovarian and endometrial cancer.

The progestin-only pill (sometimes called the "mini-pill") contains no estrogen and must be taken at the same time every day to maintain effectiveness. It is a suitable option for women who cannot take estrogen due to medical conditions such as a history of blood clots, certain types of migraines, or during breastfeeding.

The contraceptive patch (Xulane) is applied to the skin weekly for three weeks, followed by one patch-free week. The vaginal ring (NuvaRing or Annovera) is a flexible ring inserted into the vagina that releases hormones locally; NuvaRing is used for three weeks with one week off, while Annovera can be used for up to a year with a similar three-weeks-in, one-week-out cycle. Both the patch and ring have similar effectiveness to the pill.

The Depo-Provera injection is a progestin-only method given as an intramuscular shot every three months (12 to 13 weeks). It is highly effective when injections are received on schedule. However, it is associated with a possible delay in return to fertility — it may take six to twelve months after the last injection for ovulation to resume. It can also cause weight gain and a decrease in bone mineral density with long-term use, though bone density typically recovers after discontinuation.

Barrier methods physically prevent sperm from reaching the egg. The male condom is the most widely used barrier method and, importantly, is the only contraceptive option (along with the internal/female condom) that provides significant protection against sexually transmitted infections (STIs), including HIV. When used correctly every time, male condoms are about 98% effective, but typical-use effectiveness is approximately 87% due to inconsistent or incorrect use.

The internal (female) condom is a pouch inserted into the vagina before intercourse. It provides both pregnancy and STI protection but has a higher typical-use failure rate than male condoms. The diaphragm is a dome-shaped silicone cup inserted into the vagina to cover the cervix, used with spermicide. It must be fitted by a healthcare provider and left in place for at least six hours after intercourse. Diaphragms are moderately effective, with a typical-use failure rate of about 17%.

The cervical cap (FemCap) is similar to the diaphragm but smaller. Spermicides used alone (foams, gels, films, or suppositories) have relatively high failure rates and are most effective when combined with another barrier method. Barrier methods are a reasonable choice for women who prefer non-hormonal options and are comfortable using them consistently.

For individuals and couples who are certain they do not want future pregnancies, permanent contraception (sterilization) is an option. Tubal ligation (commonly called "getting your tubes tied") is a surgical procedure that blocks or removes sections of the fallopian tubes to prevent eggs from reaching the uterus. It can be performed laparoscopically, at the time of a cesarean delivery, or shortly after a vaginal delivery. Bilateral salpingectomy (complete removal of both fallopian tubes) has become increasingly common, as evidence suggests it may reduce the risk of ovarian cancer, which often originates in the fallopian tubes.

Vasectomy is a minor surgical procedure for male partners in which the vas deferens (the tubes that carry sperm) are cut or sealed. Vasectomy is a simpler procedure than tubal ligation, with a faster recovery time, lower complication rate, and is equally effective. A semen analysis is required after the procedure to confirm that no sperm are present before relying on it for contraception.

Permanent methods should be considered irreversible. While reversal procedures exist, they are complex, expensive, not always successful, and may not be covered by insurance. Thorough counseling and careful consideration are essential before choosing sterilization.

Fertility awareness-based methods (FABMs) involve tracking your menstrual cycle, basal body temperature, and/or cervical mucus changes to identify fertile days and avoid intercourse or use barrier methods during that window. With perfect use, some FABMs can be moderately effective, but typical-use failure rates range from 12% to 24% depending on the specific method. FABMs require significant commitment, consistent tracking, and are less reliable for women with irregular cycles.

Emergency contraception is used after unprotected intercourse or contraceptive failure (such as a condom breaking) to reduce the risk of pregnancy. Levonorgestrel emergency contraception (Plan B and generics) is available over the counter and is most effective when taken within 72 hours of unprotected intercourse, though it can be used up to 120 hours (five days) with decreasing effectiveness. Ulipristal acetate (ella) is a prescription emergency contraceptive that is effective for up to 120 hours and maintains its effectiveness better than levonorgestrel throughout that window. The copper IUD can also be inserted within five days of unprotected intercourse as the most effective form of emergency contraception, with a failure rate of less than 1%, and it then provides ongoing contraception for up to 10 years.

When comparing contraceptive methods, it is important to distinguish between perfect-use and typical-use effectiveness. Perfect use reflects how well the method works when used exactly as directed every time. Typical use accounts for real-world human behavior, including missed doses, incorrect application, and inconsistent use.

LARC methods (IUDs and implant) have the highest effectiveness at over 99% for both perfect and typical use, since they do not depend on user action. The pill, patch, and ring are over 99% effective with perfect use but approximately 91-93% effective with typical use. The Depo-Provera injection is over 99% with perfect use and about 96% with typical use. Male condoms are 98% with perfect use and 87% with typical use. Fertility awareness methods range from 76% to 88% with typical use.

Side effects vary by method. Hormonal methods may cause irregular bleeding, breast tenderness, headaches, mood changes, nausea, or changes in libido. The copper IUD may increase menstrual bleeding and cramping. Most side effects improve within the first three to six months of use. Serious complications such as blood clots (with estrogen-containing methods) are rare but important to discuss with your provider, especially if you have risk factors.

One barrier to LARC adoption has been concern about pain during IUD insertion. In 2025, ACOG released updated clinical guidance on pain management for IUD insertion, recommending the use of lidocaine-based approaches, including paracervical blocks and topical anesthetic agents, to improve patient comfort during the procedure. These recommendations reflect growing evidence that adequate pain management increases patient satisfaction and willingness to choose highly effective LARC methods. Discuss pain management options with your provider before your insertion appointment.

Choosing the right contraceptive method involves weighing several factors: how effective the method needs to be, whether you prefer hormonal or non-hormonal options, how important convenience and low maintenance are to you, your plans for future pregnancies and how quickly you want fertility to return after discontinuing, any medical conditions that may limit your options (such as a history of blood clots, migraines with aura, or certain cardiovascular conditions), and whether STI protection is important (in which case condoms should be used regardless of your primary method).

Postpartum contraception deserves special mention. Many methods can be started soon after delivery, but timing depends on the specific method and whether you are breastfeeding. LARC methods can often be placed immediately after delivery or at the postpartum visit. Estrogen-containing methods are generally not recommended until at least three to four weeks postpartum (six weeks if breastfeeding) due to increased blood clot risk. Progestin-only methods, including the mini-pill, implant, and hormonal IUD, are considered safe for use during breastfeeding. Discuss your contraceptive plan with your provider during pregnancy or at your postpartum visit.
