Injectable Contraceptive Study

The purpose of this study is to investigate levonorgestrel butanoate (LB) as a possible long-acting and reversible injectable for contraception. 

This study is being done in order to investigate levonorgestrel butanoate (LB) as a possible long-acting and reversible injectable for contraception. Injectable contraception is a long-acting and reversible method of birth control. An experimental injectable contraceptive containing levonorgestrel butanoate (also called LB) has been developed by the NICHD. An experimental use is one that is not approved by the United States Food and Drug Administration (FDA).

WHRU - Injection Contraceptive Study

LB is a type of hormone called a progestin. The hormone is intended to keep or delay women from releasing an egg, so they do not get pregnant and also may work by thickening the cervical mucus to prevent the passage of sperm and by preventing sperm from fertilizing an egg. Approved levonorgestrel birth control pills work the same way.  It is not known how well the new LB injection will work in preventing a woman from becoming pregnant. This study is intended to help find out what effects the hormones will have on women who receive the injection.
