Description

Summary

The primary purpose of this study is to assess the efficacy and safety of the etonogestrel (ENG) contraceptive implant during participants' fourth and fifth years of use when used as the only method of contraception. The ENG implant is currently approved for a 3-year duration, and this study aims to confirm available evidence suggesting that the ENG implant remains highly effective when used up to 5 years.
