Summary

This study tested whether a two-shot hormone schedule works as well as the usual longer schedule for women freezing their eggs for non-medical reasons. 194 healthy women aged 18-40 received either two injections of corifollitropin alfa or one injection followed by daily shots of another hormone. The goal was to see if both methods collected a similar number of mature eggs.

What this could mean

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

Active substance: Corifollitropin alfa (Elonva) and recombinant FSH
What this could lead to: If successful, this could offer a simpler, shorter hormone injection schedule for women freezing their eggs, reducing the number of shots needed.
What could go wrong: This is a completed trial, but results are not yet published. The simpler schedule may not collect as many mature eggs as the standard approach, and individual responses vary.
