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="cdc-2020" />
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="cdc-2020" />

===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|STIs]] and can be inserted up to 8 hours before intercourse. The failure rate is 21%.<ref name="cdc-2020" />

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}}
Sterilization procedures are generally considered to have a low risk of side effects, though some persons and organizations disagree.<ref>{{Cite web | vauthors = Bloomquist M |date=May 2000 |title=Getting Your Tubes Tied: Is this common procedure causing uncommon problems? |url=http://www.medicinenet.com/script/main/art.asp?articlekey=51216 |access-date=2006-09-25 |website=MedicineNet.com |publisher=WebMD}}</ref><ref>{{Cite web | vauthors = Hauber KC |title=If It Works, Don't Fix It! |url=http://www.dontfixit.org/ |access-date=2006-09-25}}{{MEDRS|date=September 2012}}</ref> Female sterilization is a more significant operation than vasectomy, and has greater risks; in industrialized nations, mortality is 4 per 100,000 tubal ligations, versus 0.1 per 100,000 vasectomies.<ref>{{Cite journal |vauthors=Awsare NS, Krishnan J, Boustead GB, Hanbury DC, McNicholas TA |date=November 2005 |title=Complications of vasectomy |journal=Annals of the Royal College of Surgeons of England |volume=87 |issue=6 |pages=406–10 |doi=10.1308/003588405X71054 |doi-broken-date=11 July 2025 |pmc=1964127 |pmid=16263006}}</ref>
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
Because of their systemic nature, hormonal methods have the largest number of possible side effects.<ref>{{Cite web |last=Staff |first=Healthwise. |title=Advantages and Disadvantages of Hormonal Birth Control |url=http://healthlinksbc.org/kb/content/frame/tw9513.html |access-date=2010-07-06}}</ref> Combined hormonal contraceptives contain estrogen and progestin hormones.<ref name="teal-2021">{{cite journal | vauthors = Teal S, Edelman A | title = Contraception Selection, Effectiveness, and Adverse Effects: A Review | journal =
Hormonal contraceptives can come in multiple forms including injectables. Depot medroxyprogesterone acetate (DMPA), a progestin-only injectable, has been found to cause [[amenorrhea]] (cessation of menstruation); however, the irregular bleeding pattern returns to normal over time.<ref name="teal-2021" /><ref name="barr-2020" /> DMPA has also been associated with weight gain.<ref name="barr-2020" /> Other side effects more commonly associated with progestin-only products include [[acne]] and [[hirsutism]].<ref name="barr-2020" /> Compared to combined hormonal contraceptives, progestin-only contraceptives typically produce a more regular bleeding pattern.<ref name="teal-2021" />

Other barrier methods, such as [[Diaphragm (contraceptive)|diaphragms]] may provide limited protection against infections in the upper genital tract.

Line 104 ⟶ 105:
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.
