Recruiting at 1 site Phase 3 Infertility (IVF Patients)

Trial comparing treatments for Infertility (IVF Patients)

Official title Cleavage-stage Versus Blastocyst-stage Embryo Transfer in IVF Patients With Few Embryos

ClinicalTrials.gov ID: NCT06746129

What this study is testing

What it's testing
This study is testing whether an 8‑cell embryo transfer or a blastocyst transfer leads to better pregnancy results and satisfaction for people with few embryos.
Who it's for
You may be able to join if you are an IVF patient with five or fewer embryos and a doctor thinks you have a poor chance of success.
What's involved
You will be randomly assigned to have your embryos transferred at either the 8‑cell stage or the blastocyst stage. You will attend the usual IVF visits and follow the same care plan as other IVF patients.
Time commitment
The study lasts until the embryo transfer and the follow‑up check‑in after the transfer, usually a few weeks.
