Conclusions of the existing survey
• In general, IVF units are comfortable with the cryopreservation techniques
• Physicians would appreciate guidelines and standardization.
• Education would be much appreciated.
• The gynecologists think that the oncologists should be more aware to fertility preservation.
• We are offering the option but the results are not yet known.
• Bias of survey – answered by units performing the procedure
