One extra shot around embryo transfer may lift IVF live birth rates
NCT ID NCT02357654
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
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

- 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.
