Birth Control Guide

Efficacy rates in this chart are based on Contraceptive Technology (16th edition, 1994). They are yearly estimates of effectiveness in typical use, which refers to a method's reliability in real life, when people don't always use a method properly. For comparison, about 85 percent of sexually active women using no contraception would be expected to become pregnant in a year.

This chart is a summary; it is not intended to be used alone. All product labeling should be followed carefully, and a health-care professional should be consulted for some methods.

Footnotes

(a) Effectiveness rate for polyurethane condoms has not been established.

(b) Less effective for women who have had a baby because the birth process stretches the vagina and cervix, making it more difficult to achieve a proper fit.

(d) Serious medical risks from contraceptives are rare.
