A pill instead of a needle? new IVF trial tests drospirenone for women with low ovarian reserve
NCT ID NCT07736261
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This pilot trial tests whether a daily drospirenone pill can replace standard daily injections during ovarian stimulation for women with poor ovarian reserve undergoing IVF. Participants take either drospirenone or the usual injection alongside their fertility hormones, then have all embryos frozen for later transfer. The study compares the number of mature eggs retrieved and tracks treatment experience through questionnaires.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a daily pill called drospirenone, compared with a standard daily injection called cetrorelix
- What this could lead to
- If drospirenone works as well as the standard injection, it could offer a simpler, needle-free option for ovarian stimulation in women with low egg reserve.
- What could go wrong
- This is a small pilot trial, so results may not be definitive. Drospirenone may not prevent premature ovulation as effectively as the standard injection, and its effects on pregnancy rates are unknown.

Inclusion Criteria: * 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 Exclusion Criteria: * Contraindication to ovarian stimulation * Known müllerian anomaly * Uncontrolled systemic disease * 5 prior failed IVF attempts * Known contraindication to drospirenone (per product labeling, e.g., renal impairment, adrenal insufficiency, conditions predisposing to hyperkalemia)
