• Embryo transfer practices
• ASRM embryo transfer guidelines
• single embryo transfer
• IVF insurance coverage

Objective: To gain a better understanding of factors influencing clinicians' embryo transfer practices.
Design: Cross-sectional survey.
Setting: Web-based survey conducted in December 2008 of individuals practicing IVF in centers registered with the Society for Assisted Reproductive Technology (SART).
Patient(s): None.
Intervention(s): None.
Main Outcome Measure(s): Prevalence of clinicians reporting following embryo transfer guidelines recommended by the American Society for Reproductive Medicine (ASRM), prevalence among these clinicians to deviate from ASRM guidelines in commonly encountered clinical scenarios, and practice patterns related to single embryo transfer.
Result(s): Six percent of respondents reported following their own, independent guidelines for the number of embryos to transfer after IVF. Of the 94% of respondents who reported routinely following ASRM embryo transfer guidelines, 52% would deviate from these guidelines for patient request, 51% for cycles involving the transfer of frozen embryos, and 70% for patients with previously failed IVF cycles. All respondents reported routinely discussing the risks of multiple gestations associated with standard embryo transfer practices, whereas only 34% reported routinely discussing single embryo transfer with all patients.
Conclusion(s): Although the majority of clinicians responding to our survey reported following ASRM embryo transfer guidelines, at least half would deviate from these guidelines in a number of different situations. (Fertil Steril (R) 2010;94:1432-6.
