NCT07736261

Brief Summary

Participants will:

  • Take either drospirenone (a daily pill) or the standard daily injection during their ovarian stimulation cycle, alongside their regular fertility hormone injections
  • Undergo egg retrieval, with all resulting embryos frozen (no fresh embryo transfer in this study)
  • Have a frozen embryo transferred in a later cycle
  • Complete two short questionnaires about their treatment experience - once before starting the injections/pills, and once after the stimulation phase ends
  • Be followed to determine if the embryo transfer results in a pregnancy

Eligibility Criteria

Age20 Years - 42 Years
Sexfemale(Gender-based eligibility)
Gender Eligibility Detailsfemale gender phenotypically and genetically
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Spontaneous menstrual cycles (21-35 days)
  • Poor ovarian response per Bologna criteria (≥2 of 3): advanced age ≥40 or risk factor for POR; previous poor response (≤3 oocytes with conventional stimulation); abnormal ovarian reserve (AFC \<7 or AMH \<1.1 ng/mL)
  • POSEIDON group recorded at enrollment (1-4) for stratified randomization and pre-specified subgroup description - corrects a known limitation of Bologna-only classification, which pools biologically distinct POR phenotypes
  • Indication for IVF/ICSI
  • Willing and able to undergo mandatory freeze-all/FET protocol
  • Signed informed consent, including explicit acknowledgment that fresh transfer is not offered in either study arm

You may not qualify if:

  • Contraindication to ovarian stimulation
  • Known müllerian anomaly
  • Uncontrolled systemic disease
  • prior failed IVF attempts
  • Known contraindication to drospirenone (per product labeling, e.g., renal impairment, adrenal insufficiency, conditions predisposing to hyperkalemia)
