- To study and compare acceptability and tolerance between breast-feeding post-partum woman, who receive contraceptive implant 48-72 hours after giving birth or at 5-7 weeks after giving birth, using either Levonorgestrel or Etonogestrel contraceptive implant.
- Participants who wish to attend the study will be invited to choose between Levonorgestrel and Etonogestrel contraceptive implant, then they will be randomized into immediate postpartum or delay postpartum group. They will be follow-up at 6 and 12 weeks after receive contraceptive implant.
- Information about side effects, breastfeeding status, child growth, acceptability and tolerance will be noted using medical records and interviewing, gathering on paper case record forms.
- Sample size N = 60 (30 in each group (Immediate and delay postpartum group, 15 in each subgroup (Levonogestrel and Etonogestrel group)) This number of sample size is already counted with 10% data loss

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of participants with treatment-related adverse events (time frame: immediately after contraceptive implant use until 12 weeks after use). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03353012, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
