Summary

This trial tests whether a lower daily dose of the fertility drug Rekovelle can produce as many healthy embryos as a higher dose in women of advanced age undergoing IVF with genetic screening. Participants receive either 15 or 20 micrograms per day during ovarian stimulation. Researchers then compare the number of normal embryos and hormone levels between the two groups.

What this could mean

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

Active substance
Follitropin-delta (Rekovelle), a hormone injection used to stimulate the ovaries
What this could lead to
If a milder stimulation works as well as a stronger one, it could reduce side effects and costs while maintaining or improving the chance of a healthy embryo in older women.
What could go wrong
This is a phase 4 trial with 110 participants, so results may not apply to all patients. The milder dose might produce fewer eggs, and the study does not yet prove live birth outcomes.
