Notes:
1. Oocyte cryopreservation cycles are not included
2. Clinical pregnancy means pregnancy confirmed by ultrasonic scan. All pregnancies reported here are clinical pregnancies. Approximately 5-10% of these pregnancies will miscarry.
3.  Frozen embryo transfer success rates based on the age the embryos are thawed and transferred (not the age in which the embryos were created and frozen).

A comparison of clinic success rates may not be meaningful because patient medical characteristics, treatment approaches and entrance criteria for ART may vary from clinic to clinic.
