E-Freeze - Freezing of embryos in assisted conception: a randomised controlled trial evaluating the clinical and cost-effectiveness of a policy of freezing embryos followed by thawed frozen embryo transfer, compared with a policy of fresh embryo transfer

E-Freeze is a multi-centre randomised controlled trial that compares fresh embryo transfer with frozen thawed embryo transfer for couples undergoing their first round of fertility treatment. The main aim is to understand if there is any difference in the chances of having a healthy baby.
