Are there specific concerns about mosaicism, outcome data, etc., and decisions patients might be making? We are very comfortable with this literature, and focus on evidence-based patient decision-making. But it is also good to know how the physicians would like us to represent their philosophies and their willingness to transfer embryos at risk for mosaicism and embryos with aneuploidies. If the physician has a specific practice policy on these issues, we'd love to know about it in advance.
