Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The aim of the present study is determining if the probabilities of embryo implantation and pregnancy are associated to the operator performing the embryo transfer.
This study allows following more than 30 different operators in a global period of 20 years with almost 20,000 procedures.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The aim of the present study is determining if the probabilities of embryo implantation and pregnancy are associated to the operator performing the embryo transfer.
The database includes all the fresh embryo transfers, performed between January 1997 and December 2016 at Humanitas Fertility Center after IVF-ICSI cycles. Only embryo transfers performed by the surgeon on duty for that day ("Gynecologist of the Day") will be included.
Secondary end point is to evaluate if it is possible to draw a learning curve for transfer in terms of pregnancies for the different surgeons.
The strength of this study relies on the completeness of the preoperative factors and follow up and on the vastest dataset in literature that can permit to correct for multiple confounders and analyze a wide group of outcomes.
