Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The primary objective is to determine the impact of the biologist performing the embryo transfer on the pregnancy probability, in terms of ongoing pregnancy rate (OPR), defined as the number of viable pregnancies that had completed at least 12 weeks of gestation on the total number of ET performed.
Secondary end point is to evaluate whether the biologists improve their performances as their experience increases, allowing the drawing of an ET learning curve in term of pregnancies for the different biologists.
The biologist's experience was assessed in terms of number of previous interventions performed prior to the day of ET. A total of 28 operators were eligible to participate in the study. Any biologists who performed less than 100 ETs was excluded from the analysis.
