http://www.guttmacher.org/media/nr/2011/11/15/index.htmlThe most common reason U.S. women use oral contraceptive pills is to prevent pregnancy, but 14% of pill users—1.5 million women—rely on them exclusively for noncontraceptive purposes. The study documenting this finding, “Beyond Birth Control: The Overlooked Benefits of Oral Contraceptive Pills,” by Rachel K. Jones of the Guttmacher Institute, also found that more than half (58%) of all pill users rely on the method, at least in part, for purposes other than pregnancy prevention—meaning that only 42% use the pill exclusively for contraceptive reasons.

The study—based on U.S government data from the National Survey of Family Growth (NSFG)—revealed that after pregnancy prevention (86%), the most common reasons women use the pill include reducing cramps or menstrual pain (31%); menstrual regulation, which for some women may help prevent migraines and other painful “side effects” of menstruation (28%); treatment of acne (14%); and treatment of endometriosis (4%). Additionally, it found that some 762,000 women who have never had sex use the pill, and they do so almost exclusively (99%) for noncontraceptive reasons.
