Can a 3 months treatment with oral Desogestrel prior to insertion of the etonogestrel-releasing contraceptive implant improve continuation rate at 1 year? A randomized trial

BMC Res Notes. 2023 Mar 13;16(1):35. doi: 10.1186/s13104-023-06304-3.

Abstract

Objective: To evaluate if daily oral 75 µg of Desogestrel (DSG) for 3 months prior to the insertion of etonogestrel-releasing contraceptive implant (ENG-IMPLANT) might help reduce its premature discontinuation.

Results: A total of 66 women were randomized in the ENG-IMPLANT group (26) and in the DSG + ENG-IMPLANT group (40), respectively, in the Geneva University Hospitals and Basel University Hospital, from August 15th, 2016 through September 30th, 2019. In the DSG + ENG-IMPLANT group, patients were given a 3 months' supply of 75 µg of DSG before the insertion of the ENG-IMPLANT. All women were seen after 3 months for bleeding and satisfaction evaluation, and at 12 months post ENG-IMPLANT insertion. Higher levels of satisfaction at 12-months were found in the ENG-IMPLANT group compared to the DSG + ENG-IMPLANT group (8.5 ± 1.7 vs. 6.6 ± 2.9, p = 0.012). There were no statistically significant differences regarding tolerance (7.8 ± 2.5 vs 6.8 ± 2.6, p = 0.191) and contraceptive continuation (80% vs 72.4%, p = 0.544) between groups.

Conclusion: DSG prior to insertion of the ENG-IMPLANT did not improve its continuation rate neither its satisfaction at 1 year. Trial registration NCT05174195. Retrospectively registered, the 30th December 2021.
