Effect of Immediate Versus Standard Postpartum Insertion of the Contraceptive Implant on Breastfeeding Outcomes

University of New Mexico·interventional·Posted Jun 7, 2019·Updated Nov 28, 2025

In Brief

A Phase 4 clinical trial evaluating Etonogestrel and Nexplanon for Contraception. Completed, enrolled 150 participants across 2 sites.

Detailed Summary

The investigators are studying the effect of placing the etonogestrel implant (Nexplanon) in the first 24 hours after birth on breastfeeding. Women who wish to have an etonogestrel implant placed after their birth, wish to breastfeed, and are willing to participate in the study will be randomly assigned to either get the implant placed in the first 24 hours after delivery of the baby and placenta or 4-6 weeks later. The investigators do not believe there will be a difference in breastfeeding 8 weeks after delivery or time to lactogenesis between those who get the implant placed early or later.
