E-Freeze is a multi-centre randomised controlled trial being conducted in the UK. It compares fresh embryo transfer with frozen thawed embryo transfer for couples undergoing their first, second or third round of fertility treatment.
The main aim of E-Freeze is to understand if having a fresh or thawed embryo transfer makes any difference in the chance of having a healthy baby.
The study protocol for E-Freeze has been published in the BioMedCentral Reproductive Health journal. You can find it here.
