NCT ID NCT03978598
First seen Sep 30, 2025 · Last updated Jun 23, 2026 · Updated 35 times
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. Researchers enrolled 150 women who planned to breastfeed and wanted the implant. They tracked breastfeeding rates at 8 weeks and beyond to see if early insertion makes a difference.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Etonogestrel implant (Nexplanon)
What this could lead to
If successful, this could show that getting the implant right after birth does not harm breastfeeding, giving women more flexibility in contraception timing.
What could go wrong
This is a small, single-center study (150 participants) and results may not apply to all women. The implant's hormone could still affect milk supply in some cases.
