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

Outcome Measures
Primary Outcomes (1)

Day 0
Secondary Outcomes (8)
Number of oocytes retrieved
Day 0
Fertilization rate 2 pronuclei (2PN)
on day 1
Quality of day-3 embryos

Patient burden score
Day 0
- +3 more secondary outcomes
Study Arms (2)
Drospirenone
EXPERIMENTAL50 cases will receive drospirenone in the form of 1 tablet / d when the leading follicle reaches 14 mm till hCG trigger day
cetrorelix
ACTIVE COMPARATOR50 cases will receive cetrorelix when the leading follicle reaches 14 mm till hCG trigger day
Interventions
A drug drospirenone in the form of 1 tablet / d from 14 mm follicle till hCG trigger day
Cetrorelix a drug injection daily sc. from 14 mm follicle till hCG trigger day
Eligibility Criteria
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)
