Which hormone best prevents endometrioma return after surgery?
NCT ID NCT07519213
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at over 1,100 women who had surgery for ovarian endometriomas (cysts caused by endometriosis) and then took one of four hormonal treatments to prevent recurrence. The goal was to see which treatment—birth control pills, GnRH agonists, dienogest, or dydrogesterone—was most effective at stopping new cysts from forming within two years. Results could help doctors choose the best post-surgery hormone therapy.

Active substance
hormonal treatments (combined oral contraceptives, GnRH agonists, dienogest, or dydrogesterone)
What this could lead to
If this study shows one hormonal regimen works better, it could help doctors choose the best option to prevent endometriomas from coming back after surgery.
What could go wrong
This is a retrospective study, not a controlled trial, so results may be influenced by unmeasured factors. The findings need confirmation in prospective studies.
