The three types of family planning are natural (fertility awareness-based) methods, temporary methods (which include barrier devices, hormonal options, and long-acting reversible contraception), and permanent methods (surgical sterilization). Each type works differently, lasts for a different length of time, and suits different life situations. Here’s what you need to know about all three.
Natural and Fertility Awareness Methods
Natural family planning relies on tracking your body’s fertility signals to identify the days each cycle when pregnancy is possible. You can become pregnant if you have sex anywhere from five days before ovulation until one day after ovulation, so these methods focus on pinpointing that window and either avoiding sex or using a barrier method during it.
Several specific approaches fall under this umbrella:
- Standard Days method: If your cycle is between 26 and 32 days long, days 8 through 19 are treated as fertile. You avoid unprotected sex during that stretch.
- Cervical mucus method: You check the consistency and presence of cervical mucus daily. A variation called the TwoDay method simplifies this by asking two questions: Did I notice secretions today? Did I notice them yesterday? A “yes” to either means you’re likely fertile.
- Basal body temperature method: You take your temperature each morning before getting out of bed. A small, sustained rise signals that ovulation has occurred.
- Symptothermal method: This combines temperature tracking with cervical mucus observation for a more complete picture.
With perfect use, meaning you follow the method correctly every single cycle, fewer than 1 to 5 out of 100 women become pregnant in the first year. In practice, most people aren’t perfectly consistent. With typical use, 12 to 24 out of 100 women become pregnant in the first year. That gap between perfect and typical use is the largest trade-off with natural methods: they require daily attention and discipline, and they offer no protection against sexually transmitted infections.
Withdrawal (pulling out before ejaculation) is sometimes grouped here as well. It’s the least reliable behavioral method because it depends entirely on timing and self-control, and pre-ejaculate fluid can contain sperm.
Temporary Methods: Barriers, Hormones, and Long-Acting Devices
Temporary methods are the broadest category. They range from something you use once and throw away to devices that stay in place for years, but they all share one feature: fertility returns once you stop using them.
Barrier Methods
Barrier methods physically block sperm from reaching the egg. The most common options are external (male) condoms, internal (female) condoms, diaphragms, cervical caps, and spermicide. They are less effective at preventing pregnancy than hormonal options or long-acting devices, but condoms carry a unique advantage: latex and polyurethane condoms are the best widely available protection against STIs, including HIV. Internal condoms also provide some STI protection, though less reliably.
Spermicide used alone is one of the least effective contraceptive options. Products containing nonoxynol-9 do not protect against STIs and, with frequent daily use, may actually increase the risk of HIV transmission from an infected partner. Spermicide works best as a backup paired with a diaphragm or cervical cap.
Hormonal Methods
Hormonal contraception prevents pregnancy by stopping ovulation, thinning the uterine lining, or thickening cervical mucus so sperm can’t pass through easily. Common forms include the daily pill, the patch (changed weekly), the vaginal ring (replaced monthly), and the injection (given every three months). All are significantly more effective than barrier methods when used consistently.
Commonly reported side effects include headaches, nausea, mood changes, breast tenderness, weight gain, and acne, though evidence linking all of these directly to the hormones is still limited. If side effects do appear, they usually improve within about three months. Hormonal contraception can also change your periods, often making them lighter or less frequent. On the risk side, hormonal methods slightly raise the chance of blood clots and breast cancer, though both remain rare for most users.
Long-Acting Reversible Contraception (LARC)
Long-acting reversible contraception includes intrauterine devices (IUDs) and the hormonal arm implant. These are the most effective temporary methods available, rivaling the success rates of permanent sterilization, and they require no daily or weekly effort once placed.
The copper IUD contains no hormones. Instead, it creates an environment inside the uterus that is toxic to sperm. It’s approved for up to 10 continuous years and has a first-year failure rate of just 0.8 per 100 women. Over 10 years, its cumulative failure rate (1.9 per 100 women) is comparable to surgical sterilization.
Hormonal IUDs release a small amount of progestin locally into the uterus. Several versions exist, approved for anywhere from 4 to 5 years depending on the specific device. They tend to make periods lighter and, for some users, stop them altogether. The hormonal arm implant is a small rod placed under the skin of the upper arm. It releases progestin steadily and is effective for up to three years.
Because LARCs work without you having to remember anything, the gap between perfect use and typical use is nearly zero. That’s the main reason they outperform pills, patches, and condoms in real-world effectiveness.
Permanent Methods: Surgical Sterilization
Permanent family planning means surgical sterilization: tubal surgery for women or vasectomy for men. Both are intended to be irreversible, so they’re best suited for people who are certain they don’t want future pregnancies.
Tubal surgery (sometimes called “getting your tubes tied”) is performed laparoscopically or through a small abdominal incision. It blocks or removes a section of the fallopian tubes so eggs can no longer reach the uterus. About 0.5 out of 100 women become pregnant in the first year after the procedure. Pregnancies can occur years later, and the risk is slightly higher for women who were younger at the time of surgery.
Vasectomy involves cutting or sealing the tubes that carry sperm from the testicles. It has a first-year failure rate of just 0.15 per 100 users, making it one of the most effective contraceptive methods in existence. After the procedure, you need to avoid ejaculation for about a week while the surgical site heals, then use condoms or abstain until a semen analysis at 8 to 16 weeks confirms the vasectomy was successful. Once a post-vasectomy semen analysis shows no sperm, the chance of pregnancy drops to roughly one in 2,000.
Neither tubal surgery nor vasectomy protects against STIs. If STI risk is a concern, condoms are still necessary.
Emergency Contraception as a Backup
Emergency contraception doesn’t fit neatly into the three main categories because it’s not an ongoing method. It’s a backup option used after unprotected sex or contraceptive failure. Four options are available in the United States: the copper IUD (placed within five days of unprotected sex), and three types of emergency contraceptive pills. All emergency pills should be taken as soon as possible within five days of unprotected intercourse, though effectiveness drops with each passing day. The copper IUD is the most effective emergency option and doubles as long-term contraception once placed.
Choosing the Right Type
The best method depends on your health, your plans for future pregnancies, how much daily effort you’re willing to put in, and whether STI protection matters. Someone with a regular 26-to-32-day cycle who is comfortable tracking fertility signs might do well with a natural method. Someone who wants years of protection with minimal upkeep is a strong candidate for an IUD or implant. Someone who is done having children may prefer the finality of sterilization.
Health factors also play a role. The CDC’s medical eligibility criteria for contraceptive use are designed to remove unnecessary barriers while accounting for conditions like high blood pressure, a history of blood clots, or migraine with aura, all of which can affect which hormonal methods are safe. A provider can help match the method to your specific medical profile, but the core decision starts with understanding these three types and what each one asks of you in return.
