Comparing two methods for oocyte collection in women with low ovarian reserve
Official title: Dydrogesterone Primed Ovarian Stimulation Versus Fixed Gonadotropin Releasing Hormone Antagonist Protocol for Oocyte Accumulation in Low Ovarian Reserve Patients: A Randomized Controlled Trial
Run by Tam Anh TP. Ho Chi Minh General Hospital · NCT05847283 · Data updated 2026-11-12
This study is testing two different methods for collecting eggs in women with low ovarian reserve to see which one helps gather more usable eggs for future fertility treatments.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are women aged 18 to 37 with an antral follicle count of 5 or less and/or an AMH level of 1.2 ng/ml or lower.
✕Probably not a fit
Patients who are oocyte recipients, have contraindications to ART, or have a history of repeated implantation failure may not benefit from this study.

What this trial studies
This clinical trial aims to compare the effectiveness of a Dydrogesterone-primed ovarian stimulation (DPOS) protocol against a GnRH antagonist protocol for oocyte accumulation in women with diminished ovarian reserve. Eligible participants, aged 18 to 37 with low ovarian reserve indicators, will be randomly assigned to one of the two treatment groups. Both groups will undergo a standardized ovarian stimulation regimen, followed by oocyte retrieval and cryopreservation. The study is designed to assess which protocol yields a higher number of viable oocytes for future use in assisted reproductive technology.
Why it matters
Potential benefit: If successful, this study could provide a more effective and patient-friendly approach to oocyte collection for women with diminished ovarian reserve.
How similar studies have gone: While there have been various ovarian stimulation protocols, the specific comparison of DPOS versus GnRH antagonist in this context is relatively novel.
