===Surgical methods===
Line 53:
[[Tubal ligation]] is also known as 'tying tubes', this is the surgical process that a medical professional performs. This is done by closing or tying the fallopian tubes in order to prevent sperm from reaching the eggs. This is often done as an [[outpatient surgical procedure]] and is effective immediately after it is performed. The failure rate is 0.5%.<ref name=":04" />
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
==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">{{cite book |editor1-last=Hatcher |editor1-first=Robert A. |editor2-first=James |editor2-last=Trussell |editor3-first=Anita L. |editor3-last=Nelson | name-list-style = vanc |title=Contraceptive Technology |publisher=Ardent Media |___location=New York |year=2011 |edition=20th |isbn=978-1-59708-004-0}}{{page needed|date=June 2012}}</ref> Intrauterine methods, implants, and sterilization fall into this category.<ref name="Hatcher20th" /> For methods that are not user dependent, the actual and perfect-use failure rates are very similar.
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.
Higher levels of user commitment are required for other methods.<ref name=WHOTable>{{cite report|title = Helping women understand contraceptive effectiveness | first1 = Kathleen Henry | last1 = Shears | first2 = Kerry Wright | last2 = Aradhya | name-list-style = vanc | url = http://www.fhi.org/NR/rdonlyres/eoabicg5w53xarcybsiefba5ruvr6r2dnkws7vj2hr3ndzv225gkvw2oxtkdlxzcl5yr3q3iok4kid/Mera08091.pdf | date = July 2008 | publisher = Family Health International}}</ref> Barrier methods, coitus interruptus, and spermicides must be used at every act of intercourse.
