Summary

This study looked at whether placing the etonogestrel contraceptive implant (Nexplanon) within 24 hours of giving birth affects breastfeeding compared to waiting 4-6 weeks. 150 women who wanted the implant and planned to breastfeed were randomly assigned to one of the two groups. The main goal was to see if there was a difference in how many women were still breastfeeding 8 weeks after delivery.
