Background and study aims
There is a lot of debates about the best area in the endometrial cavity in which to transfer embryos. The aim of the study is to compare two areas and assess the impact on implantation and pregnancy rates.
Who can participate?
Female adults going for embryo transfers at the CHA Fertility Center of Bundang CHA General Hospital
What does the study involve?
Participants are randomly allocated to one of two groups: group A = embryo transfer 2cm from fundal endometrium (DFE) or group B = at the midpoint of the endometrial cavity length (ECL)
What are the possible benefits and risks of participating?
Not provided at time of registration
Where is the study run from?
CHA Fertility Center of Bundang CHA General Hospital (South Korea)
When is the study starting and how long is it expected to run for?
From July 2012 to December 2014.
