▲==Methods==
===Hormonal methods===
The [[Intrauterine device|IUD (intrauterine device)]] is a T-shaped device that is inserted into the [[uterus]] by a trained medical professional. There are two different types of IUDs
[[Oral contraceptive pill|Oral contraceptives]] are another option, these are commonly known as '[[Combined oral contraceptive pill|the pill]]'. These
Some choose to get an [[Injection (medicine)|injection]] or a shot in order to prevent [[pregnancy]]. This is an option where a [[Health professional|medical professional]] will inject the hormone [[Progestogen (medication)|progestin]] into a woman's arm or [[buttocks]] every 3 months to prevent pregnancy. The [[failure rate]] is 4%.<ref name="
Women can also get an [[
The patch is another simple option, it is a skin patch containing the hormones progestin and estrogen that is absorbed into the [[Circulatory system|blood stream]] preventing [[pregnancy]]. The patch is typically worn on the lower abdomen and replaced once a week. The failure rate for this is 7%.<ref name="
The hormonal vaginal [[Contraceptive vaginal ring|contraceptive ring]] is a ring that contains the hormones [[Progestogen (medication)|progestin]] and [[estrogen]] that a woman inserts into the [[vagina]]. It is replaced once a month and has a failure rate of 7%.<ref name="
===Barrier methods ===
The [[Condom|male condom]] is typically made of [[latex]] (but other materials are available, such as [[Lambskin condom|lambskin]], if either partner has a [[latex allergy]]). The male condom is placed over the male's penis and prevents the sperm and semen from entering the partner's body. It can prevent pregnancy, and STIs such as, but not limited to, HIV if used appropriately. Male condoms are disposable (each condom can only be used once) and are easily accessible at local stores in most countries. Condoms have a failure rate of 2% when used correctly during every act of intercourse, and 13% when used 'typically', which includes cases where they are used inconsistently or incorrectly.<ref>{{Cite web |date=2020-01-23 |title=Contraceptive Effectiveness in the United States {{!}} Guttmacher Institute |url=https://www.guttmacher.org/fact-sheet/contraceptive-effectiveness-united-states |access-date=2025-07-01 |website=www.guttmacher.org |language=en}}</ref><ref name="cdc-2020" />
The [[female condom]] is worn by the woman; it is inserted into the vagina and prevents the sperm from entering her body. It can help prevent [[Sexually transmitted infection|
===Other methods===
[[Spermicide]]s come in various forms such as: gels, foams, creams, film, suppositories, or tablets. The spermicides create an environment in which sperm can no longer live
In the [[fertility awareness-based method]] a woman who has a predictable and consistent menstrual cycle tracks the days that she is fertile. The typical woman has approximately 9 [[Fertility|fertile]] days a month and either avoids intercourse on those days or uses an alternative birth control method for that period of time. The failure rate is between 2-23%.<ref name="
[[Lactational amenorrhea]] (LAM) is an option for women who have had a baby within the past 6 months and are breastfeeding. This method is only successful if it has been less than 6 months since the birth of the baby, they must be fully breastfeeding their baby, and not having any periods.<ref name="
The '[[Coitus interruptus|pull out method]]' or [[coitus interruptus]] is a method where the male will remove his penis from the vagina before ejaculating;
===Emergency contraceptives===
A [[Copper IUDs|copper IUD]] can be used as an [[Emergency contraception|emergency contraceptive]] as long as it is inserted within 5 days
There are two different types of [[Emergency contraception|emergency contraceptive pills]], one contains [[
Use of an emergency contraceptive should occur as soon as possible after unprotected sexual intercourse to reduce the chance of pregnancy.
Line 56 ⟶ 55:
===Surgical methods===
[[Tubal ligation]] is also known as 'tying tubes'. This is the surgical process
A [[vasectomy]] is a minor surgical procedure where a doctor will cut the [[vas deferens]] and seal the ends to prevent sperm from reaching the penis and ultimately the egg. The method is usually successful after 12 weeks post-procedure or
==User dependence==
Different methods require different levels of diligence by users. Methods with little or nothing to do or remember, or that require a clinic visit less than once per year are said to be ''non-user dependent'', ''forgettable,'' or ''top-tier'' methods.<ref name="Hatcher20th">{{
Many hormonal methods of birth control, and LAM require a moderate level of thoughtfulness. For many hormonal methods, clinic visits must be made every three months to a year to renew the prescription. The pill must be taken every day, the patch must be reapplied weekly, or the ring must be replaced monthly. Injections are required every 12 weeks. The rules for LAM must be followed every day. Both LAM and hormonal methods provide a reduced level of protection against pregnancy if they are occasionally used incorrectly (rarely going longer than 4–6 hours between breastfeeds, a late pill or injection, or forgetting to replace a patch or ring on time). The actual failure rates for LAM and hormonal methods are somewhat higher than the perfect-use failure rates.{{citation needed|date=September 2023}}
Higher levels of user commitment are required for other methods.<ref
==Side effects==
Different forms of birth control have different potential side effects. Not all, or even most, users will experience side effects from a method. The less effective the method, the greater the risk of pregnancy, and the side effects associated with pregnancy.
Minimal or no
Barrier methods have a risk of allergic reactions. Users sensitive to latex may use barriers made of less allergenic materials - polyurethane condoms, or silicone diaphragms, for example. Barrier methods are also often combined with spermicides, which have possible side effects of genital irritation, vaginal infection, and urinary tract infection.{{citation needed|date=April 2022}}▼
▲Minimal or no other side effects are possible with coitus interruptus, fertility awareness-based, and LAM. Some forms of periodic abstinence encourage examination of the cervix; insertion of the fingers into the vagina to perform this examination may cause changes in the vaginal environment. Following the rules for LAM may delay a woman's first post-partum menstruation beyond what would be expected from different breastfeeding practices.{{citation needed|date=April 2022}}

After IUD insertion, users may experience irregular periods in the first 3–6 months with Mirena, and sometimes heavier periods and worse menstrual cramps with ParaGard. However, continuation rates are much higher with IUDs compared to non-long-acting methods.<ref>{{Cite journal |last=Committee on Practice Bulletins-Gynecology, Long-Acting Reversible Contraception Work Group |date=November 2017 |title=Practice Bulletin No. 186: Long-Acting Reversible Contraception: Implants and Intrauterine Devices

▲===Sexually transmitted disease prevention===
{{main article|Safe sex}}
[[condom|Male]] and [[female condom]]s provide significant protection against [[sexually transmitted
Other barrier methods, such as [[Diaphragm (contraceptive)|diaphragms]] may provide limited protection against infections in the upper genital tract. Other methods provide little or no protection against sexually transmitted
==Effectiveness
Failure rates may be calculated by either the [[Pearl Index]] or a [[decrement table|life table method]]. A "perfect-use" rate is where any rules of the method are rigorously followed, and (if applicable) the method is used at every act of intercourse.▼
===Cost and cost-effectiveness===▼
Family planning is among the most cost-effective of all health interventions.<ref
During the initial five years, vasectomy is comparable in cost to the IUD. Vasectomy is much less expensive and safer than tubal ligation. Since ecological breastfeeding and fertility awareness are behavioral they cost nothing or a small amount upfront for a thermometer
Not using contraceptives is the most expensive option. While in that case there are no method related costs, it has the highest failure rate, and thus the highest failure related costs. Even if one only considers medical costs relating to preconception care and birth, any method of contraception saves money compared to using no method.{{Citation needed|date=September 2023}}▼
The most effective and the most cost-effective methods are long-acting methods. Unfortunately these methods often have significant up-front costs, and requiring the user to pay a portion of these costs prevents some from using more effective methods.<ref
===Effectiveness calculation===
▲Failure rates may be calculated by either the [[Pearl Index]] or a [[decrement table|life table method]]. A "perfect-use" rate is where
Actual failure rates are higher than perfect-use rates for a variety of reasons:
* Mistakes on the part of those providing instructions on how to use the method.
* Inconsistent use of the method
* Mistakes on the part of the method's users.
* Conscious user non-compliance with the method.
* Insurance providers sometimes impede access to medications (e.g. require prescription refills monthly).<ref>{{
For instance, someone using oral forms of hormonal birth control might be given incorrect information by a health care provider as to the frequency of intake, or for some reason does not take the pill one or several days, or not go to the pharmacy on time to renew the prescription, or the pharmacy might be unwilling to provide enough pills to cover an extended absence.
===Effectiveness comparison===
The table below color codes the '''typical use''' and '''perfect use''' [[failure rate]]s, where the failure rate is measured as the expected number of pregnancies per year per woman using the method:
:{| class="wikitable sortable"
Line 128 ⟶ 133:
In the '''user action required''' column, items that are ''non-user dependent'' (require action once per year or less) also have a blue background.
Some methods may be used simultaneously for higher effectiveness rates. For example, using condoms with spermicides the estimated perfect use failure rate would be comparable to the perfect use failure rate of the implant.<ref name="Hatcher20th" /> However, mathematically combining the rates to estimate the effectiveness of combined methods can be inaccurate, as the effectiveness of each method is not necessarily independent
If a method is known or suspected to have been ineffective, such as a condom breaking, or a method could not be used, as is the case for [[rape]] when user action is required for every act of intercourse, [[emergency contraception]] (ECP) may be taken
before making major changes to the table (e.g. adding or removing methods). -->
