Actual (reported)Analysis our Embryo transfer data, prospectively collected during the last 6 years (2014- 2019), performed by the same operator YP, who has been doing embryo transfers since 1984. All factors that might impact the embryo transfer will be analyzed. We want to see which factors that influence the success rate are not related to the subjectivity of the operator and could be adjusted through different approaches.
