A simple twist during embryo transfer could boost IVF success
NCT ID NCT07759765
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This trial tests whether rotating the embryo transfer catheter 360° during withdrawal improves pregnancy rates in women aged 20-35 undergoing fresh day-3 embryo transfer. Participants are randomly assigned to either catheter rotation or standard withdrawal, and researchers compare clinical and chemical pregnancy rates. The goal is to see if this simple technique change can increase the chance of a successful pregnancy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Embryo transfer catheter withdrawal technique (360° rotation vs. no rotation)
- What this could lead to
- If rotation helps, it could offer a simple, low-cost tweak to embryo transfer that boosts the chance of pregnancy in IVF.
- What could go wrong
- This is a single, early-stage trial; the technique may not improve outcomes and could carry risks like embryo displacement or uterine trauma.
