Summary

The purpose of this study is to find out whether hormonal birth control increases, decreases, or does not change the risk of women becoming infected with HIV.

Sexual intercourse between men and women is the main way HIV is transmitted. About 90 percent of HIV infections in women are caused by sexual intercourse. Also, hormonal birth controls are widely used. This study hopes to find out whether hormonal birth control changes the risk of women becoming infected with HIV.
