In plain words
The etonogestrel implant is a small, flexible rod. A provider places it under the skin of the upper arm. It releases a progestin hormone slowly and is labeled for about three years of use. It is one of the most effective forms of birth control, and it does not depend on daily action. It is a common choice after birth, and it can be placed in the hospital or at a . Some mothers notice irregular bleeding or spotting. Bleeding patterns vary from person to person. A provider can remove the implant at any point.
The deeper version
The etonogestrel implant (Nexplanon) is a single-rod subdermal device containing etonogestrel, releasing progestin at rates that suppress ovulation in most users. The CDC U.S. Medical Eligibility Criteria for Contraceptive Use (2024) lists the implant as appropriate for postpartum use, including during breastfeeding. Pregnancy rates are below 1 per 100 women per year in trials. Bleeding changes are the most common adverse effect and the leading reason for discontinuation. Evidence on postpartum initiation and bleeding patterns comes from randomized trials and cohort studies, with a consistent safety profile.
