Summary

This trial tests whether a single injection of a GnRH agonist given around the time of embryo transfer can improve the chance of a live birth in women under 40 undergoing IVF, ICSI, or frozen embryo transfer. Participants receive either the GnRH shot or a placebo, and researchers track live birth rates, implantation, clinical pregnancy, and risk of ovarian hyperstimulation syndrome. The goal is to see if this simple hormonal boost helps the uterus support a pregnancy after embryo transfer.

What this could mean

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

Active substance
GnRH agonist (single injection)
What this could lead to
If it works, this simple additional shot could increase the chance of a live birth after IVF or frozen embryo transfer.
What could go wrong
This is a single-center Phase 4 trial; results may not apply to all IVF patients. The GnRH agonist carries a small risk of ovarian hyperstimulation syndrome (OHSS).
