Answers
Birth control methods include barrier methods, hormonal birth control, intrauterine devices (IUDs), sterilization, and behavioral methods. They are used before or during sex while emergency contraceptives are effective for up to five days after sex. Effectiveness is generally expressed as the percentage of women who become pregnant using a given method during the first year and sometimes as a lifetime failure rate among methods with high effectiveness, such as tubal ligation. The most effective methods are those that are long acting and do not require ongoing health care visits.
Surgical sterilization, implantable hormones, and intrauterine devices all have first-year failure rates of less than 1%. Hormonal contraceptive pills, patches or vaginal rings, and the lactational amenorrhea method (LAM), if adhered to strictly, can also have first-year (or for LAM, first-6-month) failure rates of less than 1%.
With typical use, first-year failure rates are considerably high, at 9%, due to inconsistent use. Other methods such as condoms, diaphragms, and spermicides have higher first-year failure rates even with perfect usage.
Hormonal contraception is available in a number of different forms, including oral pills, implants under the skin, injections, patches, IUDs and a vaginal ring.
