NCT02416687

Brief Summary

The etonogestrel (ENG) implant inserted immediately postpartum reduces the risk of pregnancy recurrence, especially in vulnerable populations. A limitation to recommending this practice universally is the low quality of evidence on the effect of the ENG implant on breastfeeding when inserted immediately postpartum. This study is the first assessing the impact of inserting the ENG implant immediately postpartum on the amount of milk using the gold standard method for this purpose.
