Summary

This study measures relaxin, a hormone linked to ovulation, in women undergoing frozen embryo transfer. Researchers want to see if natural ovulation occurs in certain preparation methods. Only 5 participants with regular cycles are being recruited, and those with ovarian issues or recent hormone use are excluded.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Progesterone or HRT medication
What this could lead to: If successful, this could clarify whether natural ovulation occurs in certain frozen embryo transfer preparations, potentially improving future treatment protocols.
What could go wrong: This is a very small observational study (5 participants) and only measures a hormone level, not pregnancy outcomes. Results may not change clinical practice.
