***Patient characteristics vary among programs; therefore, these data should not be used for comparing clinics success rates.


*A comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic.

FET = all Frozen Embryo Transfer Cycles
DOR = all Donor oocyte (egg) recipient cycles


The above charts reflect Clinical Pregnancy Rates. Not all of these patients will deliver a term infant. The rates are a sum for all patients treated and may not reflect the actual chance that a couple has to conceive. The chance to conceive must be determined for each couple individually, based upon their own clinical situation as determined by their physician.
