Could a sticky solution help IVF embryos implant?
NCT ID NCT06165367
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a substance called hyaluronan to the liquid used during embryo transfer can improve pregnancy rates in IVF. Researchers will compare live birth rates between women whose embryos are placed in a hyaluronan-rich medium versus a standard one. The trial involves 783 women using genetically normal frozen embryos.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- hyaluronan-enriched medium (EmbryoGlue)
- What this could lead to
- If it works, this could improve the chance of a live birth after IVF by using a special medium during embryo transfer.
- What could go wrong
- This is a mid-stage trial, and previous studies have not shown clear benefits. The outcome depends on many factors, so success is not guaranteed.
